About Me

I am a Senior Full-Stack Engineer based in Trivandrum, India, with over 14 years of experience in the software industry. I specialize in building production-grade web applications, bridging complex back-end logic with modern, responsive front-end interfaces.

My core expertise lies in Ruby on Rails (ROR), Go (Golang), and React. I have a proven track record of developing Cloud-Native SaaS platforms and high-performance APIs. I am also deeply interested in data-driven technologies, currently expanding my skills in Python, Data Analytics, and Machine Learning/AI.

Beyond code, I am an active open-source contributor and enjoy reading, cricket, and badminton.
