Online stores from design to deployment.

About

I've been working as a full-stack developer since 2015. These days that mostly means WooCommerce and PrestaShop stores, plus integrations with ERP systems. I run the entire technical process myself, from design to deployment, so I'm accountable for the end result, not just a slice of it. For the visual layer, I team up with trusted designers.

I solve problems that cost real money in e-commerce: manually re-typing stock levels and orders between a store and an ERP, slow product pages, platforms nobody wants to touch. Over the years I've worked across different systems and integrations - I know where these connections tend to break, and how to build them so they don't.

Day to day, I work on client projects, and after hours - my own tools and AI-based automations.

    Clear communication

    Concrete agreements, hard deadlines, no ambiguity and no "someday, maybe".
