Eric PERRET

Engineer first, language second.

I design algorithms and simulations. Then I choose the right tool.
For universal deployment — PC, tablet, smartphone — the browser is the runtime.

HTML5 CSS3 JavaScript

Zero dependencies. Runs everywhere.

What I build

Signal Processing — Acoustic localization, TDOA, Doppler tracking, DVB-S transmission chains
Cryptanalysis — Classical cipher breaking, frequency analysis, dictionary attacks
Structural Engineering — Seismic simulations, TMD systems, base isolation
Healthcare Tools — Medical training, triage systems, music therapy applications

Live Demos

Project Description
code Classical cipher cryptanalysis — Vigenère, Beaufort, Caesar, XOR
photo Perspective correction for OCR/AI preprocessing
Sismic Seismic building response — TMD, base isolation
sstv Slow Scan TV encoder/decoder — Martin, Scottie
quizz Mental health training & pediatric triage
JPEG2DVB DVB-S transmission tutorial — DCT to QPSK
One-Page-One-Mission Acoustic drone tracking — TDOA, Kalman, Doppler

Philosophy

Analysis → Design → Algorithm → Then choose the language.
Not the other way around.

Portable. Autonomous. No framework. No build step.
Open the file. It works.
