Resume - Javier Lorenzo

Projects

I’m listing a variety of projects here. They encompass more than just IT, as I believe we are defined by what we create and accomplish.

Banana'sCraft

2012-2016

With my friend Chusca, we developed a Minecraft network that lasted around four years. It motivated me to continue learning computer science as I had to work in Recinet. It was a significant project, and our community reached many people worldwide, including notable Spanish personalities like Auronplay.

I will always remember this project fondly; it supported my learning and helped me navigate many personal and family challenges.

3D Printing and STEM enthusiast

2016-Present

I got my first 3D printer, a second-hand model that Álvaro from Makergal used for exhibitions and workshops. This opened up a new world for me.

I joined the maker community and learned a lot, collaborating on projects such as creating PPE for Cunqueiro Hospital during the COVID pandemic.

Sysadmin Galicia

2017

Sysadmin Galicia was a group of passionate system administrators dedicated to sharing their knowledge with the community. We organized talks about tools and best practices.

Thanks to this project, I overcame much of my fear of public speaking and gave a few talks. One was about my past project, Banana'sCraft, and how we orchestrated the container cloud, and another was about the Bareos tool.

PlátanoBarco

2018-2022

Marine Instruments is a prominent engineering company that organizes the Regata Solar event. In this event, participants are given the same solar panel and each team designs their own hull and electronics. It’s an event that combines technology and naval design, and it has been incredibly rewarding for me.

Thanks to Teltek for providing us with their facilities to build the boat for several editions.

FPV Drones

2018-2020

After the Regata Solar, my colleagues and I were eager to continue learning about RC hobby electronics, so we dived into the world of FPV and racing drones. We built several drones, continually improving them by swapping parts and testing new components.

Tutivillus

2020-2023

Tutivillus was a project that emerged from a coffee shop conversation. As a parody of the words accepted in the Real Academia Española dictionary, we created a clothing brand that reached many of our idols, such as Héctor de Miguel, Facu Díaz, and the hosts of the podcast Todopoderosos.

Marevento Náutica

2022

Designed and developed the corporate website with WordPress, including deployment and going live in production.

Peregrina

2022-Present

In September 2022, I rescued a traditional Galician sailboat, a dorna, from abandonment. The reconstruction process was arduous and lengthy, during which I learned a great deal and make some new friends such as Álvaro and to discover and appreciate Galician maritime culture. I documented this process on Instagram

Clube Mariño Salnés

2023-Present

Always seeking new adventures and people to share them with, I decided to collaborate with the Clube Mariño Salnés association, where I am now a board member. By promoting Galician maritime heritage, I manage the association’s administrative tasks and oversee its social media presence, ensuring that our documentation stands the test of time.
