With over 14 years in the software industry, I design and ship production-grade web applications that scale — bridging complex back-end systems with polished, performant front-end experiences. Based in Trivandrum, India, I collaborate with remote-first teams across the US, UK, and Europe.
My core stack is Ruby on Rails, Go (Golang), and React, with deep experience in Cloud-Native SaaS platforms, RESTful and GraphQL APIs, and microservices architecture. I actively apply Python, Data Analytics, and ML/AI to build intelligent, data-driven features in production.
Outside of engineering, I contribute to open-source projects, stay current with emerging AI tooling, and unwind with reading, cricket, and badminton.
