About

I've been coding commercially since 2022 — mostly online stores, but also CRMs and backends. Self-taught, with a slight preference for backend over frontend.

Who I am

Despite my young age I already have several years of experience building websites and web apps. Commercially I focus on e-commerce — from taking over broken WooCommerce stores, through years of growing a custom CMS, to maintaining Magento and PrestaShop. I'm comfortable on both frontend and backend, but I prefer logic, integrations and performance over pure styling.

Outside commercial work I build open-source projects: Wiki Scraper Newsletter (Go + Nuxt), a Symfony webhook engine, MoodJournal with a mobile app. Go is my favorite language — I'm currently building a business app with a partner.
