about

Backend engineer with 3 years at Zoho Corporation, building reliable, scalable systems in Java — strong in low-latency optimisation, zero-downtime migrations of 10M+ records, API framework design and database schemas that scale. Currently moving deeper into distributed systems and performance engineering through independent projects: Redis-backed job queues, provider-agnostic AI gateways. Occasionally I win hackathons too.
