At LLC FastPay, I built a .NET Core API supporting utility payments for 100+ providers through web and cashier apps. I also implemented payment services for Paysera, Keepz, and TBC.
I integrated Veriff for client identity verification and implemented a system to analyze transactions and detect suspicious patterns. I improved SQL queries and APIs, boosting performance by up to 40%.
On SmartCafe, I built a Blazor-based café management system with QR table recognition and online ordering, and integrated TBC Bank payments. I also developed its admin panel and database using Entity Framework.
For the Warehouse Management System project, I developed core backend features using .NET and built inventory and sales functionality. I also participated in designing and developing the database with the team.
