Key Strengths

  • Shipped full-stack Next.js feature end-to-end using Server Components and Server Actions with direct DB access
  • Database performance tuning with measurable improvement (indexing reduced query time ~100ms to ~30ms)
  • Scalability-minded data access patterns (cursor pagination, payload reduction, avoiding unnecessary re-renders)
  • Strong Postgres schema design (normalized tables, constraints, composite/partial indexes) aligned to query patterns
  • Validates DB optimizations with EXPLAIN ANALYZE and production monitoring
  • Built durable multi-step workflows with Temporal (retries, idempotency via constraints/keys/upserts, deterministic execution, versioning/replay)
  • Production-quality practices: risk-based testing strategy plus logging/metrics/tracing/alerts tied to user impact
  • UX/perceived-performance improvements (instant UI updates, loading/disabled states to prevent duplicate writes, clear empty states)
