Backend engineer with 9+ years building distributed systems, API platforms, and high‑throughput data pipelines. Passionate about observability, reducing latency, and shipping resilient services. Recently led a team that cut p99 latency by 40% for a SaaS serving 3M+ daily requests.
Experience
Senior Backend Engineer 2021 – present
Logixal Inc. · Pune, India
  • Designed and implemented a gRPC‑based event‑sourcing layer for a real‑time analytics platform, reducing data staleness from 5s to under 300ms.
  • Led migration of 12 microservices from monolithic CI to Kubernetes with automated canary deployments; cut deployment time by 60%.
  • Built a custom rate‑limiter in Go (token bucket + sliding window) that reduced API abuse incidents by 80%.
  • Owned observability stack (Prometheus, Grafana, OpenTelemetry), creating dashboards that reduced MTTR from 45min to 12min.
Backend Engineer II 2018 – 2021
Streamliner Technologies · Bangalore, India
  • Redesigned the core billing pipeline (Kafka + PostgreSQL) to support 10x scale; processed 2M+ transactions/day with 99.99% uptime.
  • Created an internal developer platform (IDP) using Backstage and Terraform, adopted by 8 teams across the org.
  • Optimized slow GraphQL resolvers — introduced dataloader pattern and Redis caching, improving p95 response from 1.2s to 180ms.
Backend Engineer 2015 – 2018
CodeBase Systems · Mumbai, India
  • Built RESTful APIs for a B2B logistics platform using Python (Django) and PostgreSQL, handling 500K+ requests/day.
  • Introduced Celery task queues for async ETL, reducing report generation time from 20min to under 2min.
  • Wrote integration tests and load tests (Locust); achieved 95% code coverage and zero critical production incidents for 18 months.
