Online application for posting educational content and providing users with access for study purposes. Sergey took the lead in setting up and launching a test server, undertaking the test of the payment acceptance service (Robokassa), and connecting the Yandex cloud file storage. He also took part in developing the following functionalities: registration, authorization, entry, and exit from the platform, the functionality of mail confirmation and access restoration, users’ personal account feature, and developing a subsystem of roles for access to the project, management of project employees, and the interface for creating/editing "content".
Application for Aviation School. Sergey was required to help to create an admin panel that allowed users to work with books. The main feature of the project was the encryption and decryption of books during and after downloading. This was the main requirement of the client, i.e. all books must be strictly confidential and can only be decrypted in the PadPilot Pro mobile app. Sergey fully implemented the admin panel, the frontend for the mobile application, as well as the logic for storing and encrypting/decrypting books.
Application to provide sales distribution channels for service providers. Sergey implemented a range of functions on the platform including registration of buyers via a confirmation email, a provider profile within the platform, a service request form, a bidding system (auction for the providing of services), request for the service of a specific provider, system of categories, geolocation service, online payment system, reviews and ratings, and a system to manage profiles.
NDA (Healthcare Application)
A system for automating the work of clinic staff (keeping a history of patients, appointments, diagnoses, studies, appointments, etc.). Sergey worked on the backend (Node.js). His main tasks included the implementation of query processing logic, working with the database and the logic, code refactoring, parsing and inserting system directory data (which required a lot of work with RegExp), and directory updates when a new version is released (implemented the incremental version algorithm). Also, due to the fact that Sergey was the strongest developer, he reviewed all the code written by the team.
