TypeScript, Node.js, Redis, PostgreSQL, Docker, Express.
Specialized in backend infrastructure — SDK reliability,
rate limiting, webhook delivery, and distributed state.

Distributed systems patterns — idempotency, backpressure,
and failure handling. Going deeper into Redis internals
and how production infra handles scale.

Rate Limiter SDK — Redis sliding window, fail-open error
handling, async logging. Also built WebhookDrop — webhook
delivery engine with BullMQ retries and HMAC signing.

Discussions on backend infra, SDK design, and distributed
systems. Also open to remote backend/infra roles —
especially at OSS-first companies.
