Hi! 👋 My name is Luís, welcome to my website! I am a Brazilian cybersecurity analyst currently living in Lisbon, Portugal. I enjoy solving problems and working with modern defensive computer security technologies, but have always been interested in other areas of computer engineering as well, including devops, cloud, data analysis, and blockchain. In my spare time, I'm usually either running, cooking, reading and writing, enjoying the beach, or going to music concerts (mostly Metal and Samba). I'm always up to date with the latest tech news and papers, and constantly looking out for new technologies to explore and projects to take on. I aspire to one day return to my home city of Rio and help improve its information and communications technology infrastructure. Thank you for visiting my website!
Technoland
A personal project
If we could rebuild all of our institutions, infrastructures, and information systems today from scratch, with modern technologies, knowing what we know now, could we do it better? Would we do it differently? I give one interpretation of how everything could be different in this book.
Career projects
BUPi 2.0
A project for Avanade
An DevSecOps project for a client in the public services sector - Portugal's Institute of Registrars and Notaries (IRN), part of the Ministry of Justice. Contributed as the primary cloud security engineer. My role involved setting up several key security components of the infrastructure, in addition to managing vulnerabilities, managing identities and accesses, and managing compliance within the environment.
Technologies used:
Internship projects
BUPi
A project for Avanade
An DevOps project for a client in the public services sector - Portugal's Institute of Registrars and Notaries (IRN), part of the Ministry of Justice. Contributed as the primary cloud infrastructure operator. My role involved managing users, servers, networks, automations, dashboards, and security controls.
Technologies used:
SNIRH21
A project for NTT Data
A DevOps project for a client in the public services sector - Portugal's Environmental Protection Agency (APA), part of the Ministry of the Environment. Contributed as an intern web developer. My role involved developing the front-end of the platform for aggregating data from an IoT sensor networks in the Tagus river for a unified monitoring portal.
Technologies used:
University projects
My Cardio
Final project
The final project of my bachelor's degree: a health tracking mobile application for patients in the cardiac health wing of one of Lisbon's hospitals, with data visualization and risk alert features. Accompanied by a web application made for nurses to visualize and tag patient health data with risk patterns. Built using Flutter, Node.js + Express, PostgreSQL. Built in collaboration with Hugo Duarte (programming), and Teresa Mesquita and Mayra Duarte (design, UI/UX).
Technologies used:
Machine Learning lab
An Artificial Intelligence project
A project for my Artificial Intelligence class: an experiment on the efficiency of two machine learning techniques applied to a dataset regarding the survival rate of breast cancer patients following their surgeries. Both techniques achieved an accuracy of ~85%, the first one being a decision tree calculated by hand in Excel, and the second one being an artificial neural network implemented in Tensorflow. For more information, see the report.
Technologies used:
Highly Available App with MFA
A Distributed Systems project
A project for my Distributed Systems class: a highly available (dummy) application running on replicated servers and databases, with automatic failover and strong user authentication via an authenticator app with TOTPs. The servers were configured in a master-slave system using Node.js + Express, while the databases were configured in a master-master system using Postgres + Bucardo. VMs and VNets implemented in Azure. For more information, see the code.
Technologies used:
Get Out There
A Web Development project
A project for my Web Develoment class: a fitness web application that lets you plan your runs across the city, save circuits, join teams, score points, and compete! Built with JS, HTML, CSS + Bootstrap, Mapquest, Node.js, and PostgreSQL. Built in collaboration with Felipe Gomes, and William Santana.

Summaries
Summaries of CS textbooks
A personal project
Having developed a taste for reading computer science textbooks over the course of my CS degree, I decided to compile the most important parts of some of the ones I read, in order to quickly refer to their knowledge, and help me retain their information over the years. I now share theses summaries with you. Please buy the books if you find them useful!
General Notes on Enterprise IT
A personal project
Having learned tremendously about enterprise information technology at the start of my professional career, I decided to write down the most important ideas around DevOps and Cybersecurity in the corporate environment. With Windows and Linux being the dominant operating systems at the time, I decided to learn a little bit more about how they worked as well. I now share theses summaries with you. Hope you find them useful!
Games
Pull Prizes
A university project
A computer game developed in my artificial intelligence class where the board is a graph (made of nodes and edges), and you must pull prizes in the board towards your home node to win. You can play against your computer running the minimax algorithm. You can also play against another human if you want. Written in p5.js.
Processing
A personal project
A trio of computer games I wrote up over the summer after a creative programming class in 9th grade. First time I ever programmed anything. Enjoy the games at will but look at the code at you own risk :D
Art projects
Among Other Nodes
A personal project
A short poem about the dangers of technology misuse.
