Hi, my name is

Diogo Serra.

Delivery leader with over a decade of experience scaling teams and complex operations, now building deep technical expertise in software and systems engineering. I work primarily with C, Python, and Bash, focusing on Linux, infrastructure automation, DevOps, AI, and machine learning. Currently at 42 Lisbon, I develop low-level engineering foundations through its peer-to-peer, project-based methodology, combining technical depth with business context to build reliable, production-grade systems and grow toward a career in DevOps engineering with an increasing focus on AI and machine learning.

01. About me

I'm a software developer with a passion for systems programming, AI, and machine learning. Currently sharpening my craft at 42 Lisbon, a peer-to-peer, project-based engineering programme where complex challenges are solved through collaboration, experimentation, and hands-on code.

I work primarily with C, Python, and Bash, exploring low-level development, Linux, infrastructure automation, DevOps, and intelligent systems. I care about understanding how technology works beneath the surface and building solutions that are reliable, production-ready, and secure by design.

After more than a decade in delivery and management roles within technology services and outsourcing, I'm moving into hands-on engineering with a strong foundation in people, processes, operations, and the business side of technology. My goal is to bring that experience to DevOps and systems engineering while developing deeper expertise in AI and machine learning.

Outside of code: cat person, longtime gamer, Souls games, Baldur's Gate, Path of Exile, survival games, and a Magic: The Gathering player since a young age.

Passed

Piscine

42 School · Admission

Four weeks of survival-mode coding. No teachers, no tutorials, just daily exercises, group projects and exams in C, all peer-evaluated. One of the hardest admission processes in tech education.

C Shell Peer Review Problem Solving

Passed

Piscina Reloaded

42 School · Refresher

A second dive, same intensity, sharper focus. Revisits Piscine fundamentals with harder challenges, reinforcing core C skills and the mindset that carries you through the rest of the 42 cursus.
