What I'm looking for

I’m looking for a role where I can build secure, scalable web apps and cloud-ready APIs, modernize legacy systems into modular architectures, and improve performance and reliability through strong CI/CD, monitoring, and OWASP-aligned practices.

I’m a Full Stack Developer with over 10 years delivering scalable, secure, high-performance web applications across fintech, telecom, and technology. I specialize in ASP.NET Core and modern JavaScript frameworks, and I’m especially strong in API development, database optimization, and CI/CD automation.

I’ve modernized legacy platforms into modular architectures, improved operational efficiency, and enhanced user experience through secure SDLC practices and performance-focused engineering. In my recent work, I’ve built REST APIs integrated with SQL Server, improved responsiveness with Angular, automated deployments with GitHub Actions and Docker, and strengthened security with OAuth2/OpenID Connect aligned to OWASP standards—while mentoring teammates and raising code quality through reviews.
