  • React Native app for 'Mapster' travel service

    Hybrid Mobile Apps
    The goal was to create a project that accommodates the complex creation of tours, which can be composed of car rental, accommodation, booking airline tickets, cabs, excursions, transfers on the part of the client. We also created the ability to place all these services on the part of our partners. At the same time, the project contains a global admin panel that covers all of the above functions.

    The most challenging part was to create the architecture of the project, which consists of 9 different services that unite into one complex system. We had to create the most suitable UI library, create custom components and make many identical services in a short period of time. The original goal was that all these 9 services had to be created within 3 months. They all had to be multi-currency, multi-lingual, with complex pricing systems for different types of goods. In essence, all these services are marketplaces, but with a much more complex and larger functionality for adding goods. On ordinary marketplaces, goods are added and realized according to a certain template. In our case, all these goods are very different from each other and cannot be fitted to a certain template.

    Currently, there are 2 most popular frameworks for creating cross-platform applications: React Native and Flutter. There was also a choice to create native applications for each mobile OS separately, using the Kotlin and Swift programming languages, but we decided to abandon this idea in favor of cross-platform development, since such development covers all the needs that arose during the creation of the project. In addition, such development takes much less time than native development, which also corresponded to our plans to create an MVP version of the project in 3 months. Then we had to choose between React Native and Flutter, where we initially chose Flutter and implemented the MVP version using it. We then developed and scaled this version, but the optimization of the application deteriorated quite significantly. We conducted our own research, in which we created an identical application using React Native and received a significant increase in the application loading speed from 4 to 10 times, so we continued to develop the application created using React Native. We also noticed that a React Native application takes up much less storage space compared to Flutter. We managed to reduce the size of the application from approximately 250MB to 20MB.

    In this project, we decided to use Vue.js, as it is a very flexible and rapidly evolving framework that fits almost any project.

    When the project started, the version of the framework was at the peak of its relevance. Vue allows you to develop and build a project much faster than React for example. Vue is very easy to learn and therefore popular, so there should be no problems with project support in the future.

    For the back-end we chose Django Rest Framework because this is a fairly universal web framework with serialization capabilities that reliably protects user data and conveniently organizes data migration. This framework provides its own authentication and authorization mechanisms such as token authentication, OAuth and JWT. It has excellent documentation and a large, responsive community. It also provides more flexible and powerful tools for managing API access rights.

  • '1Mobile' online tech store

    Online Stores & E-commerce
    A custom store from scratch, including design, logic, technical specifications, front-end and back-end. The service is quite large-scale and includes unique modifications that were required for the comfortable running of the business by its owner. The store needed to be fully synchronized with the current database, product and user management system and modified. The result is a full-fledged store based on the React + Django Rest Framework stack, which contains all the functionality of a modern online store, comparable to Rozetka, Cytrus, Foxtrot or Allo, as well as full SEO optimization.

  • 'CookMe' AI assistance service

    Web Programming
    The project is a recipe recommendation system based on ChatGPT and Dall-E. It offers a capability to select recipes based on the products that are available. There is an opportunity to save, share, and discuss recipes similar to a social network. There is a tariff system with various functionality and accesses inside.

    The biggest challenge was deducing appropriate prompts and constraints for the AI to produce answers in a specific, predictable format. Another interesting solution is the streaming generation of responses, which are displayed similarly to the output in ChatGPT itself.

  • 'Small Lithuania' travel game

    Web Programming
    The goal of the project was to show all the sights in an accessible and understandable form for tourists, as well as to give them the opportunity to download and find out additional information, and find it directly on the map of Lithuania.

    The map was imported from Google Maps and implemented with the Vue.js framework using svg animation, onto which points from the backend created on WordPress are displayed via the API.

    Since this project is only a continuation of a large project that was created on WordPress, it was decided to continue its creation on the same platform. Here it is needed only as an API source for displaying points on the map and a feedback form on the website.
