Professional skills

NodeJS / JavaScript



Will find the right tools and technologies for your project. I'm an eager reader on latest tech and dev stuff.


Will design background tasks & services that scale from day one. And make sure you get the most from AWS and others.


Will build your new rest API or realtime backend to let you build new features or fix old ones without final users impact.


I'm a big fan of automating everything on life. That includes deploying and running your code on production automatically.


Will get your application to notify you in case of unexpected behaviours so you can have quicker fixes.

Plan ahead

As with most of my customers, I help companies documenting and planning features and priorities to aim reaching goals.

Open Source

Fask: files analysis starter kit, based on NodeJS

This NodeJs library searches for all files within an specific folder – recursively – and sends each file info to your processing library. It takes care of multithreading, queuing and managing database connections.

Acio.js is an open source JavaScript distributed computing system for browsers. It allows run JavaScript tasks (i.e. mathematical calculations, 3d calculations, etc) across multiple browsers – in private and public networks – via its library. The jobs run securely on the users browser, in multiple processors, and goes unnoticeable for the final user in terms of performance and user experience.

auto-repos: Git, npm and bower automation


auto-repos is a group of aliases – originally designed as a zsh plugin – to help you don’t using repetitive commands across multiple directories.

It was originally made to help mitigate the pain of installing all the nodejs dependencies for a large project – ~20 directories – with a lot of dependencies between each other, so with just 2 commands all npm links and dependencies got resolved.
