Product engineering with full ownership.
Product Engineer · Full Stack
8+
years in production
I've spent 8+ years building digital products end-to-end: headless storefronts, payment platforms, point-of-sale systems, B2B portals and editorial sites.
I work with Next.js, React and TypeScript on the frontend; PHP, WordPress and WooCommerce when the project calls for it; and databases, APIs and cloud infrastructure to keep it all running in production.
My difference isn't a list of technologies, it's ownership: one person accountable for the product looking good, loading fast and being operable.
