You never build something great by doing it the same way that other people have done it.
Some business owners consider quick briefing a pretty simple formula when creating new
products. They often either overlook or skip careful planning in their development model.
But it is not as easy as it seems. What’s happening when one chooses bad briefs? What's
happening is that reality doesn't meet expectations. What's happening is that you face the
risk of idles, skips, delays, undefined budget.
The reality is that competent planning is no longer a matter of debate. It is a
The planning phase allows you to check your project—how it will work, how it will look, how
long it will take to develop a product, and how much it will cost.
Based on our experience, we have created our approach that ensures getting
things done. Our
goal is to understand your problem and identify your business targets to develop a
forward-looking, business-focused, user-centered, and result-oriented go-to-market plan. So
what it’s all about?
Planning phase allows you to:
Explore the international market as rapidly as possible
Receive a detailed tech spec, a long list of features and metrics
Identify risks in advance
and avoid them
Work without idles, skips, and delays
Get the visual design of the entire application
Plan the whole budget up to the cent
Release all stages accurately by timeline
Plan scaling, extension, and further releases
First of all, we sign an agreement considering intellectual property rights,
ownership of an app’s source code, design, and content. We define
the responsibilities, deliverables, payment structure, workflow, and deadlines. To
your business idea, we can sign a confidentiality agreement (NDA) as a promise that all
conveyed will be maintained in secrecy.
After that, we analyze your business niche, explore current market trends,
forecast the future outlook. We evaluate current and potential competitors’ success
and failures, identify all other relevant aspects. After gathering all the findings and
opportunities, we determine your product course—project goals, what is the problem we
solve, target audience we solve this problem for, timeline, players, and what solutions
are to deliver.
Based on your business needs, tech requirements, and other details
clarification, we define a project architecture—what functionality and customer
be implemented, what languages, frameworks, libraries, servers, UI/UX solutions, QA and
DevOps services to be combined to guarantee fast and easy-to-use final product. We
you with architecture that is built to last and can ensure your system quality and
Once the architecture is ready, we start crafting visual solutions. We apply
design thinking and user-centric principles to understand, validate, test, and visualize
ideas and primary user flows via static wireframes and clickable dynamic prototype.
wireframes display interactions between screens, the same as they are in the working
clickable prototype, in turn, fits the final user interface as far as possible by
the real app or website functionality and visual solutions. After reviewing all the
wireframes, receiving feedback from you, and specifying the details, we start creating
initial visual treatment.
At this phase, we write a tech spec, which allows appropriately thinking
through, avoiding wasting time on dead-end solutions, or building the wrong
Tech spec includes a set of actionable use cases and user stories, which
describe user interactions that the software must provide. It details the software
be developed, functional, and non-functional requirements so as performance, operational
requirements, constraints to be met, performance risks, business logic. Depending on a
project, a blueprint may include such options as big data processing (applying big data
algorithms), performing a large number of operations, multilevel computing, scalability,
extendibility, application modes (online or offline), parts reuse, B2B interaction
mechanisms, multilingual data and/or interfaces, data logging or versioning, interaction
with external resources, security issues, applying automated testing, unit tests, UI
After finalizing a tech spec, we provide you with a project estimation based
the initial product backlog, and answers three crucial questions—what needs to be done,
how long, and at what cost. Project estimation is broken down into high-level elements,
workforce, and timeframes and visualized via a Gantt chart, which allows defining each
of development and managing the sprints and epics with high accuracy. Every phase
a detailed workflow, with the low- and high-range estimates.
Clear goals, clear results. Immersive planning of your project is a solid
for your project success. Efforts and time spent on planning allow eliminating delays,
minimizing overhead costs, and delivering on time.
Who Is on Our Team?
Each project is matched with vetted experts, working in close cooperation
capable of solving complex large-scale tasks:

Good design is good business.
Design is no longer merely a fad, a wow factor, or just a beautiful picture. Robust design
is thoroughly planned, right down to the last detail, to provide personalization,
simplicity, convenience, care, accuracy, equal and comfortable experiences for all audience
Design is about personal responsibility. That is why we create a human-centered
design combined with inclusive mindset to find real people’s pain points to build a real
product that solves real needs.
If done correctly, good design sells, since your brand becomes a friend and
advisor people are eager to rely on and follow, not just a firm that tries only to sell some
services or stuff.
Research & Analysis
Meeting with You
First, we hold a meeting with you to ensure that we have a shared vision and a clear
idea of the future project—what it must become. Sometimes, clients come to us at
different stages of the development process. In this case, we define what has been done
already on your project to build a visual roadmap considering features to be
During a meeting, we will ask you to clarify:
Your answers are the basis for us to frame the problems
and find specific solutions.
Your product must solve real problems of real people. That is why, we start
our design workflow by figuring out who are your end-users and what they really want.
For that, we do these things:
observing user behaviors, needs, and motivations to understand what the user
experience is really like and feel what your users feel identifying a problem space for
which we are to propose solutions establishing business targets and scope of your
project setting up design strategy according to user needs, and project goals defined to
convert it into the user flows
Next, we will perform a competitive analysis to define and evaluate similar apps created
in the same niche by competitors as well as determine success stories and failures. All
that will help us figure out the right visual strategy to follow and identify specific
opportunities so that you could step ahead of competitors.
We provide UX design workflow in such a way as to ensure an effective and comprehensive
solution to your users’ problems, create a product that is easy to understand and use,
increase brand awareness, build strong relationships with your target audience. To make
something so great that keeps users coming back to, again and again. We continually
change and modify UX design to meet the fast-paced market requirements.
After completing user research and competitive analysis, we outline user
persona—a blueprint that showcases who your ideal customer is, and identifies what he or
she needs to get from your product. We build a user persona upon a clear problem
statement, user behaviors, needs, and motivations.
To discover your user persona, we will ask you
to respond to these questions:
Building empathy with your target audience allow us to build a successful
strategy, focus efforts, define specific functionality and smart design solutions that
perfectly fit your business case.
After outlining user persona, we start crafting user flow charts. These visual
representations help us demonstrate the core steps end users must take to achieve
targets set by mapping out each step. Flow charts help you, as a client, and our team
gain a shared understanding of the product as a whole. And that’s how:
outlining all the application or website screens and components requirements defining
features to be implemented and how they will work validating expected outcomes and
overall effectiveness to tackle usability issues and create an intuitive interface
iterating faster through ideas improving communication across the entire team and
determining development requirements beforehand
At this stage, we create low-fidelity wireframes to primary views of the future app.
Wireframes are not about the final design. End-users will never see them. Wireframes are
about platforms that ensure UI/UX designers and coders share the same vision as a client
and act as a basis from which experts create a real product.
Low-fidelity wireframes allow:
After finalizing UX wireframing, we move to the user interface to craft style concepts,
brand style guide, and mockups.
Style concepts showcase various variations of the entire app look and feel. We usually
offer two or three style concepts, each of which has a unique look and feel, so that you
could choose the best suitable one.
Brand Style Guide
Based on the chosen style concept, we start creating a brand style guide. This blueprint
details the visual expression of your brand. It combines standards for grid system,
layout, color palette, typography, iconography, logos, imagery, accessibility, as well
as other visual solutions to be applied to the app.
Our UI/UX design department also works within the existing brand style guide.
If needed, we can create a living brand style guide to combine your brand visual style
with the requirements of application development guidelines for iOs or/and Android. This
blueprint is synched to the current front-end code.
A brand style guide remains relevant for the years to come, or until you make
Now, we create high-fidelity mockups that represent how the app is going to look like
after its launch. Mockups help us make final arrangements concerning design elements by
combining different options of visual side and choose the one that looks the best. We
show the mockups to other team members to get feedback on what changes to make to ensure
the best possible result.
Prototype & Estimation
Once mockups are finalized, we start crafting high-fidelity clickable prototype(s) to
use it (them) for further development estimation.
High-Fidelity Clickable Prototype(s)
High-fidelity clickable prototypes showcase how the application will
function once developed. Prototypes allow testing the app long before its development,
as well as gather findings and deliverables that would otherwise be missed. With
prototypes, we gain more accurate estimates. And you, as a business owner, receive a
powerful tool for getting budgets approved or pitching investors.
Clickable prototypes help gain a shared understanding of what is to be built. Based on
it, we create an ultimate development estimate—how the app will work, how it will look,
how long it will take to develop it, how much it will cost. We outline planned releases
with defined timelines and expected costs.
Testing, Design Validation
& Delivery to Development
Before the launch, our QA engineers test clickable prototype(s) to identify and correct
potential design flaws to ensure everything goes right. After a thorough review, our Q&A
team validates the design and gives the green light to delivery to development.
Sending final prototype(s) to development.
Discipline is the best tool.
Design first, then code.
Don't patch bugs out, rewrite them out.
Don't test bugs out, design them out.
The modern digital market is continuously developing and extending. Apple and Google alone
offer about 2 million apps each, so it becomes hard to compete. That’s why you, as a
progressive business owner, should not only follow the trends and elaborate unique app
concepts but follow its progress and adjust to the audience’s needs.
Advanced web and mobile solutions guarantee superior, fast, seamless, flexible, and
easy-to-use final product.
We help improve and bring your business online through end to end custom software solutions
so that you can smoothly run your business everywhere, with no worries, without any
barriers. We create not just apps. We deliver solutions that everyone will always long to
The development process is broken down by milestones. They allow keeping a project on
track, managing deliverables, minimizing risks, and keeping within a clear time frame.
Each milestone lasts a month and implies specific tasks that our team must complete by
Based on the scheduled milestones, we plan one- or two-week sprints. We determine the
sprint goal and the project backlog items we are to work on during the sprint and define
how to complete them. For each sprint, developers are assigned a number of tasks from
the project backlog with estimated hours. Tasks contain what to build, relevant assets,
Sprint execution starts after sprint planning and ends with sprint retrospective. For
instance, sprint execution for a two-week sprint takes up from eight to ten working
days. Sprint execution covers planning tasks, performing and managing tasks, daily
stand-up meetings, weekly client meetings, hours reporting, collaboration via
appropriate project management software. Our team defines what way to meet the sprint
goal will be supreme.
After completing a sprint, we provide you with a sprint demo or several ones to ensure
that we are on the right track. Sprint demo allows you to be up to speed with the
progress of the software development process, provide feedback, as well as outline
amendments to the project backlog for planning further sprints.
Developers conduct local testing by running automated unit tests, checking code quality,
or processing manual checks. Automated testing eliminates the risk of the application
performance gap, bugs, errors, freezes, crashes in the long run.
Unit testing is about testing the smallest testable parts of an application to ensure
that every unit/component performs precisely as it was designed.
End-to-end testing is about testing the app performance and an interface flow, from
start to finish, via real user simulation testing, validating component integration, and
ensuring successful data integrity.
CI/CD testing methodology performs an integration function, including various types of
automated testing at every stage, simplifying merging newly committed code into the main
codebase. CI/CD platforms ensure regular automatic build and testing of the current
project version to identify defects and solve integration issues quickly.
In a typical, cascade-type, development model, where coders work independently on
various parts of the system, the integration stage is the final phase. It errors are
detected, it can unpredictably cause unforeseen project delays. Continuous integration
allows reducing labor-intensity and making software development workflow more
predictable due to early and constant detection and elimination of errors and
inconsistencies, minimizing risks for each build and speeding up features launch.
We follow GitHub flow to manage branch-based workflow. Each project is divided into
specific parts, which are assigned to responsible developers who complete tasks
separately. Once a developer writes code, he or she pushes it into a separate branch and
creates a pull or a merge request to the main one. A team lead reviews a code quality
and efficiency. If something goes wrong, a team lead leaves comments on what to rewrite.
If everything is okay, he or she merges a branch into the master branch, and the task is
At the end of each sprint, we conduct sprint retrospective. During sprint retrospective,
we evaluate what tasks we completed and what items we did not manage to achieve. We also
take into account other indicators to assess productivity. We discuss what we did right
and what went wrong, and consider any output to identify what we need to do, adapt, or
improve to avoid past mistakes when planning the upcoming sprint.
QA/QC engineers are responsible for maintaining product quality, regardless of the
software development life cycle. It means that they come into play throughout the entire
software development process. Quality assurance engineers review functions as they are
performed, and introduce end-to-end features/acceptance tests to ensure that your end
users receive a bug-free product that runs smoothly. QA/QC engineers are responsible for
the user flow integrity and record tests to reduce the risk of broken features or
missing components in user flows/user stories. The testing process is iterative, as once
one defect is fixed, it can disclose other hidden ones or even create new bugs. If the
task passes quality assurance, then it is sent to the project manager for review. If the
task fails quality assurance, then it is sent back to the developer for further revision
Quality assurance covers:
