What I'm looking for

I seek roles building scalable backend systems and APIs, with opportunities to optimize performance, work with .NET and cloud services, and contribute to product improvements in collaborative teams.

I am a backend and full-stack web developer with strong expertise in .NET technologies, RESTful APIs, scalable system design, and production deployments on Linux. I build production-ready applications, optimize performance, and deliver clean, maintainable code across web and mobile platforms.

My experience includes designing and maintaining scalable .NET Core APIs, implementing secure authentication (JWT, OTP), integrating Elasticsearch and Cloudflare, creating Blazor components and dashboards, and automating tasks with background workers and AI integrations to improve translations and content generation.
