About Me

I'm a backend-focused full-stack engineer with 3+ years building enterprise airline SaaS at taSki Technologies in Bengaluru. My work spans distributed systems, event-driven architecture with Apache Kafka, financial reconciliation engines, and LLM-powered automation pipelines.

I believe in end-to-end ownership — from low-level design and database modeling through to production deployment, observability, and on-call monitoring. I care about the details that matter at scale: composite indexing that turns 7-second queries into 200ms, idempotent event handlers, dead-letter queues, and dashboards that catch anomalies before users do.

I'm now looking outward — actively pursuing senior backend and full-stack opportunities across Europe, the UAE, and remote-first teams where deep systems work meets real product impact.
