On-Demand Delivery Service
Today, the world is undergoing a significant shift in the way people choose to live, buy and consume. The current emphasis on convenience has created a strong and growing demand for various types of on-demand services.
Delivery, rides, transportation/logistics, education, children/senior caregiving, household, rental properties and lounging, healthcare, fitness, beauty, staffing, dating… All these on-demand solutions have become the new normal.
Businesses now need to be value-oriented and offer more innovative ways to save consumers’ time and effort. What’s more, an ideal service has to aim at giving customers freedom of choice, adapting to routines for those with tight schedules, ensuring the greatest of ease.
Here is where Lezzoo comes into play as a lifesaver for consumers. Thanks to the app, people can get food, market supplies, pharmacy/cosmetics, groceries, flowers, laundry, gas. Even dog walking services!
Lezzoo was planned to act as an aggregator, uniting a wide variety of suppliers and offering consumers to pick out needed stuff at their fingertips in a matter of seconds to be delivered to the door.
The platform had to serve three distinct groups: customers, couriers and service operators. Our team was not engaged in this project at a fresh start, as the customer version of the app has already been completed.
This way, we had to create a new system that would help manage couriers, while at the same time integrating it with an already existing one, which is responsible for serving end-users. More than that, our task was to build an admin section of the system along with its UI/UX design.
This project is ongoing. The development has been going on for seven months. We work with two-week sprints, conduct daily dev team meetups and have calls with a client two times per week for making updates. After each sprint, we provide our client with a sprint demo to ensure we are on the right track. On top of that, we have personal meetings with a client.
We use individual solutions for each feature to ensure the seamless experience for all parties.
A client has an existing customer system we must integrate with. End-users can log in to make and view their orders, save their favorite suppliers/products, chat with a customer service, along with many more features that come with an on-demand delivery service.
For the admin section, we applied a role-based access control (RBAC). It means that service managers are able to dynamically create roles by type: Admin, Super Admin, Supervisor, Dispatcher. Accordingly, a client can structure his team, assign different roles, give a set of permissions regarding respective areas of responsibilities.
Features we implemented for service managers:
Сreating and filtering cities by country.
Breaking down each city into subzones with custom pricing.
Creating and editing courier and admin teams.
Selecting vehicles (car, bike, etc.) and assigning them to courier staff, grouping drivers by pick-up points.
Tracking orders in real time—both regular ones and courier delivery service by taxi drivers.
Order history split by completed tasks and earning history calculated via an app.
Actionable ranking system/rating leaderboard for couriers.
We developed a mobile version for courier staff and provided these functions:
Picking suitable orders.
Setting order status: accepted/rejected, on its way, picked-up, dropped-off, completed.
Tracking personal stats and rank rating.
For each order there is a chat with a team of dispatchers to report any issue.
We applied the following tech stack to serve our client’s business needs.
For the project, we have built a microservices architecture with NATS and bull-queue.
Microservice architecture allows maximizing deployment velocity and application reliability. It ensures an app scalability, integration with third-party services, reusability plus efficiency.
Microservices ensure fault isolation. That is, if an error occurs in one service, an entire application does not stop functioning. This is so because all components can be developed, deployed and maintained independently, being spread across multiple servers/data centers. Accordingly, an error can be fixed and deployed to respective service without redeploying the whole app.
CI/CD is configured for both frontend and backend so that a client can instantly see the result. All changes are deployed to AWS.
Also, we applied CQRS which allowed maximizing the app performance, scalability and security too.
Eight people were engaged in the project—a project manager, a designer, six developers.

Our client’s revenue strategy is built upon charging delivery fees regarding time/distance/services.
