About this Gig
I develop scalable backend systems using languages such as JavaScript, TypeScript, Python, Java, C#, Go, Rust, PHP, and Ruby, running on Node.js, Deno, and Bun. My experience includes frameworks like Express.js, NestJS, FastAPI, Django, Spring Boot, ASP.NET Core, Laravel, and Ruby on Rails. I design and implement APIs (REST, GraphQL, gRPC, WebSockets) with secure authentication methods (JWT, OAuth 2.0, OpenID Connect, Session Authentication). I apply architectural principles (MVC, Clean Architecture, Hexagonal, Monolithic, Microservices) and conduct thorough testing (Unit, Integration, End-to-End).
