Gurugram

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+ transactions/day (200K+ daily bookings), 11% attach rate, 15% conversion uplift. Premio Award — highest internal engineering award. Owned and drove cross-team platform unification (ixigo + confirmTkt): migrated 200+ APIs via 3-phase zero-downtime rollout; response times −40%, infrastructure costs −25%. Drove structured hiring, mentored engineers 1:1, authored RFCs and design docs adopted as org-wide standards; presented technical direction to senior leadership.

Bangkok

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 global production on-call rotations; high-velocity CI/CD (10+ daily releases, feature flags, canary deployments).
Arcesium (D.E. Shaw & Co.)

Gurugram

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; reduced production incidents 35%.

Gurugram

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 enterprise clients on unreliable networks.
