A bit about me.
I'm a computer science student at AIUB who builds full-stack web applications across the MERN and MEAN stacks — services, APIs, and the interfaces wrapped around them.
A lot of my time goes into AI & ML: LLMs, prompt engineering, RAG pipelines, and small agents that do something genuinely useful. I care about turning models into tools people can actually use.
On the side I keep the fundamentals sharp — networking (TCP/IP, OSI), cloud (AWS), and 2000+ solved problems across LeetCode, Codeforces and HackerRank. Open to software roles and collaboration.
