PadPilot Pro

Developer

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.

Healthcare Application

Developer

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.
