About me

Over the past 15+ years, I’ve been building and maintaining web platforms across a wide range of technologies. I’ve worked on everything from TYPO3 and WordPress projects to modern applications deployed on Vercel, AWS, and GCP.

I’ve shipped end-to-end products, including e-commerce platforms like a Shopify merch store with custom blockchain-based payments. I enjoy combining proven tools with emerging technologies to build scalable, practical solutions.

My focus is on designing systems that perform well, scale reliably, and are built to evolve.
