Projects

Things I've built from scratch, each one solving a specific problem with deliberate trade-offs.

Throttle

A standalone rate-limiting service in Go with three algorithms (Token Bucket, Sliding Window and Fixed Window), letting any application rate limit through a single API call.
Redis Lua scripts make rate-limit checks atomic, preventing race conditions when multiple servers check the same limit at once.
Deployed to Kubernetes with Prometheus and Grafana driving KEDA autoscaling on p95 latency. Load testing surfaced a Postgres connection-pool bug causing failures during scale-up; fixing it raised throughput 12%.

A RAG-based legal rights advisor for India. Users describe a situation in plain language and get their rights, remedies and law citations across eight central Indian acts.
Hybrid retrieval combines vector similarity search with keyword matching over 1,420 ingested law sections, and responses stream back over server-sent events.
In-memory caching skips redundant LLM calls, and a confidence scoring system falls back gracefully when retrieval scores are too low.

A code judge that checks whether you understand your own solution, not just whether the output matches.
Python submissions run in a fresh Docker container per test case: no network, 128 MB of memory, read-only filesystem, hard time limit. A 202-plus-polling architecture over Sidekiq keeps the web process non-blocking.
On acceptance, Gemini generates three follow-up questions specific to the submitted code and grades the answers.
