Experience

1. Senior Software Engineer

   Veeva Systems

   Aug 2020 — Present · Pleasanton, CA, US

   Architected and scaled Spring Boot and Node.js/TypeScript microservices for Vault workflow execution (approvals, lifecycle states, audit events) backed by PostgreSQL, boosting peak throughput 2.4× and cutting p95 latency 680ms → 310ms through query tuning, caching, and tighter service boundaries.* Led a reliability + release overhaul by standardizing Docker images and deploying services to AWS EKS (Kubernetes) with HPA autoscaling, health probes, and zero-downtime rollouts; improved release cadence biweekly → daily and reduced rollback incidents 45%.* Built compliance-grade traceability across a mixed stack (Spring AOP + Node.js middleware) for audit logging, security, and transaction context propagation, enabling end-to-end event lineage across 12+ services and passing validation reviews with 0 critical findings.* Deep-optimized PostgreSQL reporting and metadata queries (indexes, window functions, aggregation strategies), shrinking a key workflow dashboard query 9.2s → 1.1s (88% faster) and reducing peak DB load by ~30%.* Designed and shipped versioned REST APIs across Spring MVC and Node.js/TypeScript services with consistent error contracts, pagination, and idempotency keys; lowered integration defects 38% and accelerated partner onboarding by ~3 weeks.* Refactored admin UI workflows using React + TypeScript for grid-heavy operational screens, improving render performance 20% and reducing time-to-first-interaction by ~400ms, cutting “slow screen” support tickets by ~25%.* Implemented production observability and operational dashboards using AWS CloudWatch (SLIs/SLOs, alarms, log correlation, trace IDs), cutting MTTR 32% and identifying overprovisioned capacity savings of ~$180K/year.
