About

I build backend and infrastructure systems that move real product and cost metrics. At Flash AI — used by 10M shoppers — I've driven ~$240K/year in cloud savings, built hybrid search over ~1M products at ~100K searches/day, and shipped the in-app conversational shopping assistant. Before that, at RootQuotient, I modernised a healthcare data platform for cancer-registry workflows — moving legacy database logic into maintainable TypeScript services, building a reliable HL7 ingestion pipeline with distributed locking and worker-level scaling, and raising backend quality through stronger test coverage and CI/CD. I'm strongest in backend, distributed systems, infrastructure cost engineering, and AI agents at the application layer. Core stack: Java, Go, Python, TypeScript, SQL, Spring Boot, FastAPI, Gin, Node.js, PostgreSQL, Redis, Elasticsearch, Typesense, pgvector, AWS, Docker, OpenTelemetry. I'm most interested in SDE-2 / L4 / E4 / IC3 roles in backend, platform, and distributed systems, based in Bengaluru and open to relocation across India, the EU, or the UK. If you're hiring for high-ownership engineering roles where scale, system design, and business impact all matter, feel free to message me.

Work experience

Software Engineer at Flash AI, Dec 2024 - Present · 1 yr 10 mos, Bengaluru, • Architected and shipped Flash AI's in-app conversational shopping assistant end-to-end — a Google ADK multi-agent backend with autonomous tool use, SSE-streamed narration, and a prompt-caching tier — scaling to 1.4M monthly active users with a 20% retention lift. • Designed and built a hybrid Typesense search layer over ~1M products, lists, and categories, now serving ~100K searches/day. • Built Flash's catalogue-ingestion pipeline with multi-stage deduplication, reaching 95% merge accuracy across discovery surfaces. • Re-engineered email storage from the ground up — moved MIME bodies out of RDS into tiered S3 with lifecycle policies, re-partitioned core tables with nested keys, and purged ~2B legacy records — cutting storage 66% and halving S3 write spend. • Cut Flash's monthly cloud spend from ~$38K to ~$18K (~$240K/year) by re-architecting the AWS footprint: RDS rightsizing, ECS autoscaling, VPC subnet redesign, S3 Glacier tiering, and DB cluster consolidation. • Led an organisation-wide OpenTelemetry rollout across 28 services, migrating off CloudWatch to Last9 — cutting observability spend 30% while improving system visibility.

Software Engineer at RootQuotient, Jun 2023 - Nov 2024 · 1 yr 6 mos, Chennai, • Modernised a hospital cancer-registry platform via a strangler-fig migration from PL/SQL stored procedures and triggers to TypeScript services on SQL Server with Prisma — re-platforming the REST API layer across 102 normalised tables in two phases. • Replaced Oracle's time-based DB scheduler with an HL7 ingestion pipeline running no-overlap consumption on the cluster master — with database-driven schedules, hold-and-retry semantics, and IPC-propagated cron interval updates. • Reimplemented the legacy .NET SOAP webservices in Node.js using WSDL XML contracts and edge-js .NET interop. • Drove the test suite to 85% coverage, ran k6 load tests for on-prem capacity planning, and owned the Azure DevOps CI/CD pipeline.

Software Development Engineer Intern at Amazon, May 2022 - Jul 2022 · 3 mos, Bengaluru, • Designed UUID-based dashboard versioning on an EMR Spark job, lifting publish cadence from weekly to every second. • Re-architected an internal audit-logging system: built a diff algorithm to surface row-level changes between versions, and moved dashboard serving directly to S3, eliminating the need to maintain a million-row DynamoDB table.
