Backend engineering, with AI built in.

I'm a Computer Science undergrad at IIIT Nagpur, focused on the server side: APIs, queues, workers and databases, with LLMs as a core part of the system.

I've moved backtests onto Celery and Redis workers, sandboxed user code in Python, and generated quiz questions with an LLM API. Alongside that I build agentic systems with RAG and tool calling, and practise DSA on LeetCode and CodeChef.

60%Faster backtests with async workers
80%Fewer API calls with a PostgreSQL cache
1,000+API requests a day on LearnSphere
600+DSA problems solved
