This is my temporary cartoon face. Real face available upon coffee.

Who is this guy?

I'm Alejandro, a fourth-year Dual Degree student in Data Science and Telecommunication Engineering who thought one degree wasn’t stressful enough.

I like turning math, code, and wires into projects that actually work (most of the time). I’ve played with machine learning models for business optimization, tested security on real systems, and built hardware tools using STM32 – basically, if it can crash, I’ve probably crashed it at least once.

When I’m not debugging, I co-run QRsume, where we help people turn boring PDFs into living, breathing resumes with QR magic.

What I bring to the party
  • Adaptability & flexibility – I survive changing syllabuses and group projects.
  • Problem-solving – I break things until they start working.
  • Leadership – co-founder vibes and group-project damage control expert.
  • Time management – 2 degrees, 1 startup, 24 hours (still the same for everyone).
  • Teamwork – I speak human, not only Python.

Toolbox & Superpowers

Languages I speak: Spanish (Native), English (C1), and occasionally C when the compiler behaves.

Java · Python · C
JavaScript · PHP · MySQL
R · SQL · Spark · Hadoop

Side Quests & Main Storyline

2020–2022
Dual Diploma & Early Web Adventures

Finished high school with a Dual Diploma and took an online course in JavaScript, PHP and MySQL. Realized the web is basically one giant playground (with a lot of broken CSS).

2022–Present
Double Degree Mode Activated

Started a Dual Degree in Data Science and Telecommunication Engineering at UC3M. Also began building websites for small businesses and co-founded QRsume to fight boring resumes.

2024–2025
Purdue, UCF & Global Side Quests

Flew to Purdue University for Computer Science & Electrical and Computer Engineering courses, after summer English studies at UCF. Discovered that debugging is a universal language.

Internships & Real-World Boss Fights

On the hunt for internships where I can mix data, hardware, and web tech to solve real problems (and maybe break production… just a little).

Projects & Other Experiments

QRsume – CVs with Superpowers

Co-founded QRsume, a platform that turns static resumes into interactive portals using dynamic links and QR codes. Because PDFs deserve a glow-up too.

Snake Game on STM32

Implemented a Snake-style game using buttons, LED matrix, TFT display and SD card on an STM32 microcontroller. Proof that retro games never die, they just move to smaller screens.

C Assembly Embedded

Cybersecurity: Buffer Chaos

Explored stack, heap and side-channel vulnerabilities in C. Learned how to both break things with buffer overflows and then pretend to be responsible by implementing mitigations.
