About Me

Generalist developer with a strong focus on web API development, and experience with frontends, team management, devops, and product. Increasingly involved in the transformation of teams and architectures.

Main domains: transport (rail, mostly), finance, ecommerce, education and publishing.

Some clients: Apple, JPMorgan, Bluecode, Trainline and Rail Europe.

Consultancies: Mainmatter and Dockyard.

I work in the US and European markets.

I’ve worked on several large-scale, high traffic applications.

I have been coding in Ruby for well over a decade, on several projects with long-lived Rails monoliths. Lately doing a lot of performance tuning.

Also delivered a couple of commercial projects in Elixir, dabbled with Elm and Java, did a few years of PHP and Javascript.

I am currently working on open source Rust projects.

What else…

In a past life I was a History major at the University of São Paulo (Brazil), and studied photography at the International Center of Photography in New York.

I am Brazilian/American, binational.

Besides native English and Portuguese, I speak (passable) Catalan, Spanish, French and Italian.

For a couple of years I worked on an open source Liquid Democracy API for democratic decision-making platforms like Decidim with a few friends and colleagues. The project didn’t quite take off, but I learned a lot about this ecosystem that shows promise amidst the current dystopia of social-networks rage politics and surveillance. And about open source in general while at it.
