What I'm looking for

I'm looking to build secure, scalable systems, contribute to architectural excellence, and support business growth through business-driven technical solutions.

I've delivered backend and full-stack systems for Gradion Vietnam, ZINIO, Hybrid Technologies, and Transcosmos Technologic Arts across e-commerce, fintech, travel tech, and crypto. My work includes RaiffeisenNetworld, where I reduced PHPUnit test runtime from one hour to five minutes, and Verso, where I helped launch the VSO altcoin and blockchain-based payments.

I translate customer requirements into clear delivery plans, lead technical problem-solving and code reviews, and collaborate closely across backend and frontend teams. I build secure, scalable systems with PHP, Symfony, Laravel, JavaScript/TypeScript, cloud infrastructure, databases, testing, and DevOps tooling.
