What I'm looking for

I’m seeking senior full-stack, frontend engineering, or technical lead opportunities where I can architect secure services, build responsive React/Angular UI, integrate global payments, and collaborate with cross-functional Agile teams.

I’m a Full-Stack Developer with 5+ years architecting and delivering scalable web applications across fintech, e-commerce, logistics, and service marketplace domains. I specialize in React.js, Angular, Node.js, and TypeScript, with deep expertise in RESTful API design, OAuth 2.0/JWT authentication, RBAC, and multi-regional payment gateway integrations.

I’ve shipped four end-to-end production platforms (Zaha Vacation Homes, Bogo, Daily2You, and Traydi) and improved performance and reliability—optimizing database schemas to reduce API response latency by 50% during peak traffic and delivering enterprise-grade authentication systems that reduced unauthorized access incidents to zero. I also bring hands-on IT management experience, maintaining 100% uptime on ORP servers over a 12-month tenure while hardening security and updating a WordPress platform.
