About me

Who am I

Hi! I'm Rafał, a programmer from Poland 🇵🇱. Online I go by @rafalohaki. I build websites, web apps, APIs and backends.

On the frontend I work with Astro, Svelte, and React. On the backend with Go, Java, and Python. I also take freelance gigs from clients abroad, for example I recently built a site for a company in Paris.

I like code that's simple and won't be a headache six months later. I have hundreds of repos on GitHub, contribute to open source, and outside of coding I'm into AI, homelabbing and cybersecurity.
