About

I'm Jani Kowalski.

A full-stack developer and Codeable Certified Expert. I build and maintain WordPress, PrestaShop and Astro sites, and I build nuvols.app.

I came to web development from business, and it still shapes how I work: I start with what a site has to achieve, then choose the technology.

Since 2021 I have completed 530 projects for 55 clients on Codeable, with a 5.0 rating. Beyond WordPress, WooCommerce and LearnDash, I work on PrestaShop stores and, more recently, Astro sites on Cloudflare.

AI changed what one engineer can deliver, so I changed how I work. I write my own MCP servers, contribute to open-source tooling such as wp-devdocs-mcp, and keep every change behind review gates. nuvols.app is built the same way.

Where I work

I am based in Spain and work with clients worldwide, in English and Polish.
