/03How I work

A four-step process, calibrated to your pace.

/01Wk 1–2

Diagnosis

Two weeks listening — every flow, every spreadsheet, every workaround.

/02Wk 3

Architecture

Mapping product decisions. What is critical vs. cosmetic.

/03Wk 4–8

Prototype

Real React, real data, real constraints. Tested with end users.

/04Wk 9+

Ship & mentoring

I build alongside your team. I leave them a system they can scale.

/04Technical expertise

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.

/05Live lab
Interactive demo · security

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.

Enter the labEphemeral · no PII · rooms are wiped after 2h

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.
