About Me

Engineering Story

I am a Full Stack Software Engineer building web applications, REST APIs, and database-driven business tools. My strongest work is in Python and FastAPI backend development, JavaScript and React interfaces, and practical delivery with PostgreSQL, MongoDB, Docker, and cloud fundamentals. At PyGenicArc, I reduced average API response latency by ~25% through query and pipeline optimization.

I work across Python, JavaScript, SQL, React, FastAPI, REST API design, input validation, exception handling, PostgreSQL, MongoDB, Git, GitHub, Docker, AWS, and Azure. I care about secure coding, observable systems, clean Git workflows, and shipping reliable features from implementation through deployment.

What I Bring

✓Production backend optimization (25% latency improvement)
✓Real-time AI infrastructure (Ollama, LangChain)
✓API security & input validation best practices
✓Full-stack project delivery
✓Problem-solving mindset
✓Continuous learning & growth
