Having entered the world of computers at the tender age of 5, with a TIMEX 2048, I began programming in BASIC at 7 and I have since then developed my knowledge in several areas of IT.

I have several years of experience in various programming languages, like Python, PHP, C++, Javascript, HTML, CSS and others I use less often, like Assembly.

Nowadays I spend most of my time with Python, with a fair amount of Javascript thrown in, and tools like Docker, Redis, Terraform, Vagrant, Gulp, AWS, Google Cloud Platform, MySQL, PostgreSQL, etc.

Django is my favourite generic web framework. Rails is great too, and if I have to use PHP, then I choose Laravel.

I am a pragmatic perfectionist. I always strive to do the best thing while trying to maintain a healthy balance between perfect and practical. Well built software, with organised, clean and tested code, making use of best practices and proven methodologies is a beautiful thing.

Being also an environmentalist at heart, I always strive to do what's best for the environment and I constantly try to spread awareness of "little big" things that anyone can do and can make a huge difference for everyone on the planet.

I have also always been connected to sports since I was young. Besides bodyboard, surf and MTB, which I do regularly, I practised swimming for 9 years, rowing for 4 years (including a national championship and lots of smaller regional races), and Kung Fu and Tai Chi since 1998.

I am cheerful, sociable, easy going and a person of principles, greatly appreciating values such as honesty, humility, righteousness, patience and loyalty.

External Consultant


Wall-i is a digital signage solution that aims to be easier and cheaper than the vast majority of competing solutions by using low-cost hardware like Raspberry-Pis and other mini-computers.

I was brought on board to help create a minimum viable product to install on a few select retail chains as a test. This included re-creating from scratch all the Python code for the media player and media synchronisation on the Raspberry-Pi, improving the operating system configuration, and fixing existing functionalities on the web application (written in Laravel 5).

There were also features with which the previous team was struggling and asked me to take over, like a queue management system implemented entirely by me from scratch using Django, and an alarm scheduling solution for scenarios such as factories where a bell rings to signal beginning and end of workers' shifts.

This was a part-time job, taking up around 4 hours per day, 5 days per week.

Led the recruiting efforts for the development team.

The product had a micro-services architecture, with parts written in Python, Go and Java. On the hardware side, it deployed various brands of equipment and a custom hardware solution was being developed with Raspberry Pis, Ubuntu Core and Salt.

This started as a part-time job taking up around 4 hours per day, 5 days per week, until August 2015, when I joined the company full time.

Web developer, systems administrator, trainer

Fernão Mendes Pinto Secondary School

My main responsibility was to maintain the school's website, which at first was based on a very simple Content Management System created by myself with PHP and MySQL. As time passed and the needs increased, the CMS was moved to Drupal, which, although no longer maintained by me, is still the CMS in use.

In 2006 Moodle was added as an online resource for students and teachers, and the site was moved to a Virtual Private Server, the maintenance of which was also my responsibility.

Google Apps was also used to provide email accounts for all the school's staff, as well as all the other online tools Google Apps offers. Students were supposed to also have email accounts and the solution to manage the accounts was already in place but the school board never decided to go ahead with it.

I also provided training for teachers about the online tools they had available, as well as several workshops about various computer-related subjects, including linux and open source software.

This was a part-time job, taking up around 4 hours per day, 5 days per week.
