I build scalable distributed backend systems from 0→1 for high-volume platforms.
IndiaWhat I'm looking for
I'm building scalable distributed systems at PhonePe after leading ixigo’s event-driven backend platform, serving 10M+ daily requests at 99.9% uptime with p99 latency below 100ms.
At ixigo, I built Alternate Travel Plan from 0→1, scaling it to 22K+ transactions a day and contributing to an 11% attach rate and 15% conversion uplift. I also led a zero-downtime migration of 200+ APIs across ixigo and confirmTkt, reducing response times by 40% and infrastructure costs by 25%.
Previously at Agoda, I owned Java and Scala services for global accommodation search across 200+ countries, improving page loads by 30%. At Arcesium, I built reconciliation microservices for $100B+ AUM and helped move processing from batch workflows to Kafka pipelines.
I enjoy defining technical direction through RFCs, designing reliable event-driven systems, and helping engineers grow through structured hiring and 1:1 mentorship.

Work history, roles, and key accomplishments
Senior Software Engineer at PhonePe, building scalable distributed systems.
Defined technical direction for ixigo’s event-driven backend platform (Kafka + Kubernetes) — authored RFC, made tradeoff decisions on async/sync boundaries, partition strategy, and failure recovery; owned production rollout serving 10M+ daily requests at 99.9% uptime, p99 <100ms.
Built Alternate Travel Plan 0→1 — Kafka event processing, idempotent refunds, DLQ-backed retry; scaled to 22K+ transac
Owned Java/Scala backend services for global accommodation search, resolving distributed performance bottlenecks and reducing page load by 30%.
Owned Java/Scala backend services for global accommodation search — multi-region active-active, 200+ countries, 80M+ monthly visitors, $21B+ revenue; designed foundational marketplace-scale services across geographic regions.
Resolved distributed performance bottlenecks (Redis caching, query plan optimisation, N+1 elimination) — 30% page load reduction, validated via A/B experiments. Active in gl
Built financial reconciliation micro-services (Java/Spring Boot) for $100B+ AUM — exactly-once semantics (idempotency keys, transactional outbox, pessimistic locking), real-time validation, zero data loss across distributed transaction processing.
Drove Kafka pipeline adoption over legacy batch processing — authored tradeoff RFC, 99.9% data accuracy, DLQ retry topology, Datadog SLO alerting; redu
Built financial reconciliation micro-services with exactly-once semantics, driving Kafka pipeline adoption and reducing production incidents by 35%.
Built Java/C#/.NET backend for enterprise workflow management — 60% case processing time reduction, REST APIs with Redis caching sustaining 200+ concurrent users, 50% DB load reduction via query optimisation.
Designed fault-tolerant large-payload ingestion pipeline with resumable chunked streaming, retry semantics, and idempotent processing — 90% reduction in transfer failures, unblocking enterpr
