What I'm looking for

I seek roles building secure, scalable backend systems on Azure, with strong engineering practices, mentorship opportunities, and measurable impact on reliability and performance.

I am a Senior Software Engineer with 9+ years building scalable, secure enterprise applications across fintech and education sectors, focused on C# and .NET Core MVC, WebAPI design, and Azure cloud infrastructure. I have a proven track record delivering high-availability systems (99.99% uptime), architecting OAuth2/JWT security solutions, and optimizing performance to reduce latency and operational costs.

I led cross-functional teams, mentored junior engineers, and instituted department-wide development practices including CI/CD, unit-test automation, and Git/Azure DevOps workflows that measurably improved code quality, deployment cadence, and incident reduction. I prioritize secure, production-ready solutions that protect user data and scale with business needs.
