I’m a Full Stack Software Engineer who takes end-to-end ownership—from architecture to production hardening—building real user value with clean, scalable systems. As one of 4 founding engineers, I’ve driven framework selection, data modeling, and infrastructure decisions while shipping a hyperlocal service marketplace.

I designed and built RESTful APIs in Node.js with a JWT authentication system (refresh token rotation, Redis-backed blocklist, and replay-attack detection), and I secured 100% of endpoints with zero security incidents post-launch. On the data side, I optimized PostgreSQL schemas (10+ models, composite indexes, soft deletes, and encrypted PII), and I migrated from MongoDB—reducing average query response time by 45% while improving integrity and scalability.

Earlier, as a Full Stack Developer Intern at Tedekstra, I migrated legacy UI to React.js and Next.js, cutting codebase complexity by 40% and establishing a reusable component system. I also integrated React UIs with Node.js backend services via NestJS—using DTO validation, global exception filters, and request interceptors—reducing redundant network calls by 30% and improving error traceability.

In my projects, I enjoy event-driven and distributed problem-solving: I architected TriggerHub, an event-driven workflow automation platform using Kafka and the Transactional Outbox Pattern (processing 100K+ events/day). I also built MoneyTxn, a scalable P2P digital wallet with ACID-compliant transfers, idempotent webhook processing, HMAC-SHA256 signing, and BullMQ reconciliation, stress-tested at 5,000+ concurrent transactions with zero data inconsistency.
