What I'm looking for

I'm looking for backend .NET work on scalable APIs, integrations, fintech products, or distributed systems, ideally with remote international opportunities.

I've built backend functionality for Access Softek's digital banking platform, integrating services with banking core systems and supporting fintech workflows. Previously at Qoden Technologies, I developed .NET microservices for crypto wallet and exchange operations, including Fireblocks sweeper services and ADA and DOT blockchain integrations.

At Business Booster Platform, I delivered Google Calendar synchronization, weekly planning logic, approval workflows, statistics, and REST APIs. I work with C#, .NET, ASP.NET Core, PostgreSQL, Docker, Redis, gRPC, and cloud-ready CI/CD practices to build maintainable backend systems.
