Final-year engineering student at BIT Mesra, Ranchi, who ended up falling in love with backend systems — APIs, caching, queues, the stuff that keeps things running when nobody's watching. Two backend internships in: shipped 10+ production REST APIs at Rookus Ventures LLP, and scaled a library platform from 20 to 600+ users at Stedzo. 350+ LeetCode problems deep and still counting.

🔭 Latest build: ClickPipe — a real-time click analytics pipeline (Redpanda → Python → ClickHouse → Grafana) that sustains 20,000 events/s with p99 397 ms and loses nothing under kill -9. 🎬 Watch the demo

🩺 Also built: a full-stack pneumonia detection platform (CNN, ~94% accuracy), written up as an IEEE-format paper.

⚡ Known for: shaving 25% off API response times and then immediately looking for the next thing to optimize.

Redpanda (Kafka) Python ClickHouse Prometheus Grafana Docker

Streams every URL-shortener click through Redpanda into ClickHouse with idempotent writes, a dead-letter queue and live Grafana dashboards.

• ⚡ 20,000 events/s for 5 minutes on a single 4-vCPU machine, p99 397 ms end-to-end
• 🔁 1M-event replay with 50K duplicates → every event stored exactly once
• 💥 kill -9 mid-stream → zero data loss; 100% of bad records routed to a DLQ
