Built internal admin/analytics and operations dashboards in React/TypeScript with typed contracts and scalable Node.js REST APIs, and has deep microservices experience with Kafka/RabbitMQ (idempotency, retries/DLQs, partitioning, consumer tuning, and observability).

Key Strengths

  • Owned end-to-end delivery of notification and recommendation services used by millions of users
  • Rapid iteration using metrics-driven experimentation (CTR/conversion), feature flags, A/B tests, and incremental rollouts
  • Strong reliability practices: CI/CD, monitoring, and fast rollback when metrics dip
  • Designed scalable, strongly-typed React/TypeScript + Node.js systems with domain-based modular architecture
  • Handled scale challenges in event-driven microservices (Kafka/RabbitMQ) with idempotency, retries, DLQs, and observability
  • Performance optimization across stack (API response shaping, caching, React memoization/lazy loading)
  • Built and drove adoption of internal tools for non-engineering teams via shadowing, weekly feedback loops, and clear time-savings
  • Owned end-to-end production feature (frontend, backend, AWS deployment/ops) for high-scale notifications/engagement
  • Performance tuning under peak traffic: DB contention fixes (profiling, indexing, join optimization, reduced writes)
  • Scalability via async processing with Kafka consumers, Redis caching, and batching
  • Operational excellence on AWS: monitoring, alarms, tracing, and autoscaling for traffic spikes
  • Zero-downtime migration strategy (backward-compatible changes, dual writes/reads, rolling deploys, batched backfills)
  • Reliable integrations/pipelines: idempotency, retries with exponential backoff, reconciliation/backfills, alerting
  • High-ambiguity startup execution: shipped MVP payment integration with evolving requirements and iterated post-launch
  • Maintainability improvements in microservices: standardized API contracts, shared modules, cleaner layering; reduced bugs and improved onboarding
