About Francesc

Senior Back End Web Developer | Ruby on Rails | Elixir/Phoenix | Former Startup CTO

Experienced back end developer with a strong foundation in Ruby on Rails, Elixir/Phoenix but also worked with Scala, PHP, and Python. Over the years, I’ve worked in both freelance and full-time roles, delivering robust and scalable solutions across a variety of industries.

While my current focus is on back-end development, I also have past experience working on the front end, which helps me better understand full stack architecture—even though it’s no longer my main area of expertise.

I’ve held CTO roles at small startups, leading product development, defining technical direction, and driving projects from concept to deployment.

I'm especially interested in finance, investments, e-commerce, sustainability, green energy, travel, pets, and music. Open to collaborations (permanent jobs & contracts) and meaningful projects that merge technology with positive impact.
