Hi, I'mRahul Kumar Mall

FullStack Developer

Frontend that feels right, backends that hold up, and the LLM plumbing in between.

I enjoy creating elegant solutions to complex problems, and I keep learning whatever the next problem needs — retrieval pipelines for language models, the APIs and data behind a product, or an interface that simply has to feel right.

Off the clock I'm a PC gamer — which is partly why I care about frame budgets and things that feel smooth.
