Based in Lausanne, I came to software development through Fine Arts (**MFA, ENSBA Paris**) and hands-on technical coaching in a makerspace. That path shaped how I think about products and the people who use them.

### What I'm working on

My core stack is **Ruby on Rails** and **Vue.js** . I have been working as a **Senior Fullstack Engineer** for 6 years, currently at **Wemind** where I maintain a Rails 8 app and a Vue.js/TypeScript member space used by **11,000 members**.

### Teaching & speaking

I taught **700+ students** at **Le Wagon Paris** between 2020 and 2023, which sharpened my ability to explain complex systems to non-technical people. I also presented **GitBar**, a macOS plugin I built in Ruby, at the **Geneva.rb** meetup in January 2026.

### Open source

I recently launched **[MeridianWay](https://meridian-way.ch)**, a pedestrian navigation app that calculates two walking routes based on sun exposure : one in the sun, one in the shade, using **Leaflet** and **OpenStreetMap** building shadow data. I also published **[mark-don](https://github.com/paultursuru/mark-don)**, a Rails gem that serves any view as Markdown by appending .md to any URL, and **[astro-mark-don](https://github.com/paultursuru/astro-mark-don)**, its Astro counterpart. This portfolio uses astro-mark-don. I also built **[NuTrack](https://github.com/paultursuru/nutrack)**, a nutrition tracker using **Rails 8**, **Turbo Streams** and **RubyLLM** with the **Mistral API**.

### Beyond engineering

Outside of engineering, I keep a more personal space for my visual and artistic work at [art.paul-lahana.com](https://art.paul-lahana.com), and [paul-lahana.com](https://www.paul-lahana.com) is the little hub where you can pick which side to explore, art or dev. I also run my own brand, [hottter.ch](https://hottter.ch).

This portfolio is built with **Astro** . Some things I built: [MeridianWay](/projects/meridian-way), [mark-don](/projects/mark-don) and [GitBar](/projects/gitbar-macos-plugin). See all of them on the [Projects](/projects) page.
