petfinder
joxe
A four-step process, calibrated to your pace.
Diagnosis
Two weeks listening - every flow, every spreadsheet, every workaround.
Architecture
Mapping product decisions. What is critical vs. cosmetic.
Prototype
Real React, real data, real constraints. Tested with end users.
Ship & mentoring
I build alongside your team. I leave them a system they can scale.
Scalable Architecture
I design distributed, modular systems built to grow. Monorepos, robust APIs, and solid design patterns.
Performance First
Speed is a feature. I optimize Core Web Vitals, API response times, and database efficiency.
Code Quality
Rigorous testing (Unit, E2E), strict static typing, and clear documentation. Maintainable code is profitable code.
Hall of mirrors:
I recognize you without cookies.
I built a device fingerprinting lab to make visible something almost no one sees: your browser exposes dozens of signals (canvas, GPU, fonts, audio) that together form an almost unique fingerprint. Scan a QR code, join a room, and a live board identifies you without login and without cookies.
The goal? To make you feel it: go incognito, clear your cookies, and come back. It recognizes you all the same. And it ends by teaching you how to defend yourself. A demo that explains privacy and tracking without slides.
Scan and join
Several devices link to the same room via a QR code - like a classroom or a live event.
It recognizes you, it does not log you in
A custom collector cross-checked against FingerprintJS. Come back incognito and the revisit counter still goes up.
Learn to defend yourself
Ends by explaining why incognito isn't enough and what actually works: Tor, resistFingerprinting, and more.
