Pink lines. Red team.

I work the space between a weak technical signal and a defensible finding — research, applied methodology and the tooling that supports both.

Three surfaces. One methodology.

workstation is where the methodology lives. academy is where it's taught. labs is where it's practised.

about

Offensive security with research, tooling and execution.

I work across bug bounty, offensive research, open-source tooling and cybersecurity education with a strong bias toward execution. The goal is simple: cut noise, move faster and make technical judgment something you can write down and reuse.

Most of the day-to-day sits between the obvious finding and the report — triaging weak signals, validating ownership and authority, and turning a hunch into something a reviewer can act on.

The structured methodology lives in workstation — a research surface I built and use actively. The study program lives in academy.

I also teach offensive security at master's and vocational training level — hacking ético, bastionado de redes y sistemas, and puesta en producción.

what I do

Built around signal, speed and validation.

Four threads. Same posture: practical, methodology-first, no theatre.

🎯

Bug Bounty

Attack-surface mapping, hypothesis-driven testing and validation focused on impact, not noise. Active on HackerOne.

🔬

Security Research

Turning weak technical signals into reproducible findings with clear security value. Methodology-first, always.

🛠

Tool Development

Building tooling that removes repetitive friction from recon, triage and validation work. Open source, on GitHub.

📐

Cybersecurity Education

Teaching offensive security through execution, workflow and applied reasoning. Master's and FP level.

teaching

Cybersecurity education through execution.

I teach offensive security at master's and vocational training level. Methodology-first, not slideware.

Hacking Ético

Web application security from first principles — HTTP semantics, same-origin, auth flows, triage methodology.

FP / Máster

Bastionado de Redes y Sistemas

Network and system hardening: attack surface reduction, configuration review, detection and response fundamentals.

FP / Máster

Puesta en Producción

Secure deployment, CI/CD security posture, infrastructure hardening and operational security for practitioners.

FP / Máster

Online Course (coming)

A structured offensive methodology course. Practical, execution-driven. Follow updates on academy.

writing

Writeups and methodology notes.

Long-form offensive research writeups. Technical, methodology-first, no fluff.

Writeups are in progress. The methodology behind them already lives in workstation — signals, workflows, edge cases, playbooks. The writeups will document the real cases behind those artifacts.

Publishing via Substack. Subscribe to get notified when the first writeup drops.
