What I'm looking for

I seek backend/API roles where I can build scalable systems, automate CI/CD, optimize databases, mentor small teams, and deliver measurable performance and engagement improvements.

I am a Backend Software Engineer with 2+ years of hands-on experience designing, developing, and deploying scalable APIs and microservices that improved customer flow and system performance. I build data-driven applications using SQL and NoSQL databases and integrate external services to deliver reliable solutions.

I have implemented CI/CD automation with GitHub Actions, reducing deployment time by up to 80%, and optimized database queries to achieve fast API responses (~300 ms). I have integrated services such as Firebase Cloud Messaging to boost engagement and collaborated closely with UI teams to deliver SPA-compatible APIs.

I lead backend efforts on projects like school management and asset tracking, have experience with ASP.NET Core, Dapper, EF Core, PostgreSQL, MSSQL, MongoDB, Docker, and AWS, and I enjoy solving performance and automation challenges while mentoring and coordinating small teams.
