About ›

" HELLO.

I'm Sagar Gupta, a results-driven CS Engineering student (CGPA: 9.18) currently working as a Web Developer at Flewny, maintaining production apps built with Node.js, React, Next.js & PHP. I love building real-world solutions that create impact — from scalable full-stack platforms to intelligent AI chatbot systems.

I also explore Prompt Engineering — crafting precise, effective prompts to unlock the full potential of LLMs. Hackathon 2nd Place winner for "The Silent Voice", a real-time AI recognition system. For me, code is about connecting ideas with people seamlessly.
