Computer Engineering student at UCM, focused on low-level systems, cybersecurity and cryptography.
About
I am a Computer Engineering student at Universidad Complutense de Madrid (UCM).
I care about security, cryptography, and low-level systems. I hold the ISC2 Certified in Cybersecurity (CC) credential. I approach problems with a research mindset: measure, explain, and ship systems that hold up.
Recent work includes a VGC decision engine in beta with community testers, a native student dashboard used by classmates, and crypto tools from scratch (C++ to WASM).
Projects
-
CharmeleonProject
Decision engine for competitive Pokemon VGC: imperfect-information solvers, offline replay review, and a local bot. 13 beta testers from the VGC community. Public beta landing; core still private while in development.
Python · game theory · CFR+ / ISMCTS · offline review
-
Trayectoria
Game inspired by GraphWar, but where the level design helps you understand the International Baccalaureate maths functions syllabus. Hand-written math parser and engine, zero dependencies, and a serverless site to play in the browser.
TypeScript · Vite · canvas · Pratt parser · Vitest
-
Pass
Native desktop dashboard for students: calendar, Markdown notes, study sessions, and multi-device sync. Used day to day by classmates at UCM.
C++20 · Qt 6 · SQLite · Google Calendar · Git sync
-
PassPort
Turns voice or text into PASS tasks, events, and notes on device. Local LLM and STT so content stays on the phone; syncs over a private GitHub repo.
