What I'm looking for

I'm looking to build secure, scalable backend systems and reliable data pipelines, with opportunities to work on API design, concurrency, payments, real-time infrastructure, and repeatable CI/CD deployments.

I've built secure backend systems at Techbank, including merchant API key authentication in Laravel that replaced reversible encryption with SHA-256 one-way hashing and supported high-throughput traffic. I also deployed real-time platform health, uptime, and incident-reporting dashboards.

Across Node.js projects, I've prevented flash-sale inventory overselling with Redis Lua scripts, built idempotent order pipelines with BullMQ and PostgreSQL locking, and created crash-safe data ingestion and webhook-processing systems with retries, dead-letter queues, and live dashboards.
