Experience
Proof of✦Work✦
A look at the skills I've built and the technical tools I rely on to break down hard problems.
soft
skills
Strategic Logic
When something breaks I don't stop at the symptom — I keep pulling the thread until I find where it actually went wrong. CTFs taught me that the hard way.
Leadership
Somebody has to make the call when a CTF final is falling apart with twenty minutes on the clock. I've gotten comfortable being that person.
Collaboration
I've learned to trust teammates who are better than me at the things I'm not, and to speak up the second I notice something they've missed.
Translation
I can explain a vulnerability to a security engineer and to my mom, and neither conversation loses the point.
Resilience
New tool, new stack, deadline in six hours — I've stopped being precious about doing it "my way" and just learn the thing.
Observation
The bug that matters is usually the one nobody flagged. I've gotten weirdly good at noticing what's just slightly off.

✦What I Learned
That 'this is boring' doesn't mean skip it — the theory I side-eyed freshman year is the stuff I now reach for the most.
Started College
Entered the Faculty of Engineering. The moment curiosity turned into formal discipline. Started building the foundation of logic, algorithms, and structural thinking.

What I Learned
That security is a mindset before it's a toolset. I learned to ask 'how would I break this' before 'does this work.'
Joined Puma Hat Cybersecurity Team
Selected for the cybersecurity student group of the Faculty of Engineering. Shifted focus from passive learning to active offense. First exposure to real-world CTF dynamics and collaborative hacking.
2iterated, not finished
What I Learned
That this industry runs on who you actually talk to, not just what you can do. Showing up mattered more than I expected.
Networking events w/ Puma Hat
Attended various cybersecurity networking events and CTFs in Mexico City and Guadalajara. Connected with industry leaders and expanded my understanding of the Mexican cybersecurity landscape.

What I Learned
That a real client's infrastructure is nothing like a CTF box — you move carefully, document everything, and explain risk in plain language, not just 'critical/high/medium.'
Pentesting internship
Executed my first professional Pentesting Service, validating vulnerabilities for the Sports Study Center at UNAM as part of an agreement with Puma Hat.
4iterated, not finished
What I Learned
That placing well is about triaging fast, not knowing everything. Half the battle is knowing when to abandon your first idea.
HackMex CTF
Competed and classified in the CTF HackMex finale, landing a 7th place (R00tk1t) nationally.

What I Learned
That being the least experienced person in an unfamiliar system forces better questions than being the most comfortable one.
Student Mobility Program
Accepted into the Pisa university for a winter semester abroad as a part of the student mobility program at my college.
6iterated, not finished
What I Learned
That a good idea dies fast if you can't explain it in two minutes to someone who isn't technical.
Road to START Mexico City
Top 3 finalist in the START Hackathon Mexico City. We built a platform that automates the scientific Climate Action Roadmap, helping mexican small and medium business.
7iterated, not finished
What I Learned
That automating a manual audit process is mostly understanding why humans did it that way first — the scripting part is the easy 20%.
Internal Audit & Information Security Intern - BMV Group
Gained hands-on experience in internal audits and information security practices at the Mexican Stocks Group where I developed various scripts for automating security tasks.
8iterated, not finished
What I Learned
That shipping something people at a real company depend on every day hits different than shipping a personal project.
Software Development Intern - S&P
Worked on various software development projects, focusing on adding features in existing internal tools and creating full report pipelines for business intelligence.

NEXTWAVE Hackathon 2026 — Yuno × Nauta
Built with a team of four. Savvy watches live payment traffic, tells a genuine conversion drop apart from normal noise, and instead of just firing an alert, gathers the evidence and recommends what to investigate first — then reports it to a dashboard and Slack.
View RepositoryMexico City Transit Graph
Personal Project
Modeled almost the entire public transportation system of Mexico City — metro, metrobús, and more — as a graph, so a route between any two stations can actually be computed instead of guessed from memory.

Structure & Computer Programming Coursework
Built with two classmates for our computer architecture class — steps through Z80 assembly instruction by instruction and shows what's actually happening in memory and registers as it runs.
View RepositoryAI Battleship
Artificial Intelligence Coursework
Battleship with a graphical interface, built with a classmate for our AI course — you can play against an AI, or set two differently-trained models against each other and pull statistics on which strategy actually wins more.

Artificial Intelligence Coursework
Third lab for our AI course — search algorithms applied to solving a scrambled Rubik's cube. Group project, splitting the state representation and the search logic between the three of us.
