About me

I'm a Computer Science graduate (B.Tech '25) who likes connecting complex backend logic to interfaces that feel simple. I start with the problem, then pick the tools. Right now I'm deepening my full-stack skills and exploring data science, so I can build software that is smarter as well as faster.

Based in: Kolkata, West Bengal

Now: Full-stack Developer at Accutai

Focus: Next.js, Flask, deployment, LLMs

Degree: B.Tech CSE, GMIT
