I'm Florin, from Motril, in the south of Spain. I've just finished a Double Degree in Computer Engineering and Business Administration at the University of Granada. I work mostly with Linux systems, cybersecurity and applied AI.
I studied a Double Degree in Computer Engineering and Business Administration: five years split between programming subjects and business ones. I wasn't sure about it at first, but over time I've come to see the point. On top of the technical side I understand how a company works from the inside, and that helps when the time comes to justify a decision.
Where I work best is Linux and Docker. I have built an eight-server web farm comparing four different load balancers, put a ModSecurity WAF in front of a deliberately vulnerable application to see what it really blocked, and set up HTTPS and iptables firewalls on containers. Beyond that I have worked on fairly different things: an e-commerce site with Node and MongoDB, a Flutter app with a Rails backend, augmented reality with OpenCV and several C++ projects.
I'm now looking for a first job in something to do with systems, security or artificial intelligence. I'm also working on my English, which is the part I find hardest. If something here fits what you need, drop me a line.
Every project has its own page with the demo, the link to the repository (except the ones marked private) and the written report where there is one. The demos are recordings of real runs, not screenshots or mock-ups: this site is static and there is no server behind it. The recordings themselves are in Spanish.
interactive demo An Android app and pipeline that pull steps, sleep, body composition and workouts out of Health Connect, Samsung Health, FitDays and Hevy, and carry them into Notion and a web dashboard on their own, without the subscription those export apps charge for.
Bachelor's thesis: an engine that, given a company profile and a legislative control, deterministically infers which technical requirements ENS, NIS2 and DORA impose on it, and runs a conversational audit that issues a traceable, scored verdict.
An assistant that lets you handle your finances by voice or in writing: check your balance, send a Bizum (the Spanish instant transfer system), analyse transactions in plain language and produce charts that the model itself designs.
prototype A full case study, from user research to a working prototype. We started by auditing Goiko's website, and the redesign flips the work asked of anyone with food allergies: instead of hunting through a separate PDF for what they cannot eat, they filter on arrival and the menu shows only what they can.
A complete e-commerce site with an Express + MongoDB backend, an authenticated REST API, a React frontend and a containerised deployment with Caddy as the reverse proxy.
A Web Application Firewall sitting between the client and a farm of web servers, with OWASP CRS rules and a measurement of what it costs in performance.
Design, deployment and evaluation of a scalable web farm: load balancing compared across five technologies, TLS, firewalling and benchmarking.
A turn-based maze game implemented in full in two languages, comparing how each one solves the same object-oriented design.
A Flutter application with a Ruby on Rails backend for managing academic events organised in a hierarchical tree of months, weeks, days and events.
A C++ system that models each language by the frequency of its character pairs and classifies an unknown text by measuring its distance to the known models.
The full Python course from the Networking Academy. I also took Introduction to Cybersecurity and, later, Python Essentials 1.
Two open courses from the University of Granada: one on free software, the other on machine learning applied to biomedical data.
CEFR level B1 in the four skills: listening, reading, speaking and writing.
