About
Full-stack engineer who built and operated a data-driven analytics platform using Next.js App Router/Server Components and TypeScript, owning post-launch monitoring and performance/stability work. Demonstrated measurable wins in analytics performance (e.g., cutting query latency from ~1s to ~200ms) through indexing, query-plan analysis, and precomputation/caching, and has experience designing durable multi-step backend workflows with retries, idempotency, DLQ, and time-correct ordering.

Key Strengths
- End-to-end full-stack delivery with Next.js App Router + TypeScript in production
- Performance tuning under high concurrency by mixing SSR/CSR/Server Components/ISR and caching
- Database performance optimization using slow logs + EXPLAIN, indexing, and query rewrites
- Reduced complex analytics query latency from ~1s to ~200ms via composite indexes and precomputation
- Designed relational data models with constraints (PK/FK/NOT NULL/UNIQUE) and query-driven indexing
- Built durable multi-step backend workflows with retries, idempotency, DLQ, timeouts, and ordering guarantees
- Balances speed vs quality in high-growth environments by shipping MVPs with monitoring and core-path tests
- Strong ownership across design, implementation, monitoring, and cross-team coordination
