About

I'm a Staff Backend Engineer with 10+ years of experience building distributed systems, high-throughput APIs, and backend services at scale — across fintech (CoinDCX), e-commerce (Wayfair), and enterprise (Walmart, Deloitte, BT).My core work is designing and shipping backend systems in Go and Python that handle real load, real failures, and real complexity. That means API design with proper auth (OAuth2, OIDC, JWT), data pipelines that aggregate and serve at volume, event-driven architectures on Kafka, and services built to stay up — 99.95% SLO isn't a target on a slide, it's something I've had to engineer and defend.A few things I've built that I'm proud of: • A distributed telemetry ingestion service in Go that processes traces across 30+ microservices — replacing a $40k/year vendor with an in-house system that gave us full control over the data pipeline• A multi-cloud billing aggregation API serving 15+ teams at 1K–100K req/day, with a Redis caching layer keeping p99 latency under 120ms• An OAuth2/OIDC auth backend with RBAC and SSO integration, built from scratch for internal developer APIs at CoinDCX• A disaster recovery orchestration backend that automated multi-region failover at Walmart, cutting DR execution time by 80% I work across the full backend stack — Go, Python, Django REST, PostgreSQL, Redis, Kafka, AWS/GCP/Azure, Kubernetes, OpenTelemetry — but I'm not a stack loyalist. I care about whether the system is well-designed, observable, and doesn't wake someone up at 3am.Currently based in Bengaluru. Open to backend engineering roles — product companies, fintech, high-scale consumer systems, or B2B SaaS.

Work experience

Staff Backend Engineer at CoinDCX, Nov 2025 - Present · 11 mos, Bengaluru, Karnataka, India, • I lead backend engineering for CoinDCX's internal developer platform — designing and building the core APIs, auth systems, and data pipelines that power engineering productivity across 100+ engineers in a high-throughput fintech environment. • Key work includes architecting an OAuth2/OIDC authentication and authorization backend from scratch, building a distributed telemetry ingestion service in Go that replaced a $40k/year vendor, and designing self-service REST APIs that cut service onboarding time by ~60%. I also built a fault-injection backend service that runs automated failure simulation loops against our trading systems, helping us maintain a 99.95% uptime SLO.

Senior Backend Engineer at Wayfair, Aug 2024 - Nov 2025 · 1 yr 4 mos, Bengaluru, Karnataka, India, • Built backend services and APIs that accelerated developer workflows at one of the world's largest e-commerce platforms. My work sat at the intersection of backend systems and developer tooling — designing the APIs and services that engineering teams depended on daily. • I designed a suite of RESTful environment provisioning APIs in Python/Django REST that dynamically spun up and tore down isolated dev environments on demand, reducing setup time by 70%. I also built a privacy-safe synthetic data generation service that masked PII from production snapshots and synthesized realistic test data — cutting provisioning time by 80% while maintaining compliance. Separately, I wrote a Go-based workload validation service that intercepted 100% of incoming Kubernetes workloads and enforced security policy programmatically.

Senior Backend Engineer at Walmart Global Tech India, Jun 2021 - Aug 2024 · 3 yrs 3 mos, Bangalore Urban, Karnataka, India, • Designed and built high-throughput backend services and APIs serving 15+ engineering teams across Walmart's global multi-cloud infrastructure (GCP, Azure). • My most significant project was a multi-cloud Cost Insights API in Go — a billing aggregation service handling 1K–100K requests/day, with a Redis caching layer that kept p99 latency under 120ms and reduced DB load by ~70%. I also co-architected a disaster recovery orchestration backend that automated multi-region failover sequencing and verification, cutting DR execution time by 80%. Additionally, I built a PKI certificate lifecycle management service in Go integrated with HashiCorp Vault, fully eliminating manual certificate rotation incidents across the org.

Backend Engineer at Deloitte, Apr 2020 - Mar 2021 · 1 yr, Bengaluru, Karnataka, India, Built Python microservices and internal REST APIs for capacity planning and resource forecasting across 50+ hybrid cloud deployments. Also developed custom Prometheus exporter backends and automated incident remediation webhooks that reduced MTTR by 40%.

Backend Engineer at British Telecom Global Services India Limited, Mar 2019 - Apr 2020 · 1 yr 2 mos, bangalore, Designed and built a centralized release orchestration API in Python/Flask that abstracted Jenkins CI/CD pipelines behind a clean REST interface, accelerating release cycles by 3x. Re-engineered manual deployment workflows into Python-driven automation services, saving 20+ engineering hours per week.
