Building robust solutions
with precision and purpose.

I'm a Freelance Full-Stack Developer and Computer Science student at Karunya Institute, Coimbatore. I specialize in building real, working software — from high-performance web apps to intelligent, AI-powered tools that solve business problems.

Currently focused on engineering production-grade applications, custom automation scripts, and RAG search systems. I help clients turn their concepts into robust, scalable MVPs while maintaining clean codebases.

Open to freelance projects & contract work
