About Stéphane

Founder of Genesis RetroTech, I support industrial companies facing electronic boards without documentation: I reconstruct schematics, bills of materials (BOM), and manufacturing files (Gerber) from existing hardware — to maintain, requalify, or remanufacture obsolete equipment.
My approach is strictly documentary (no manufacturing or repair): you keep control, I deliver an exploitable technical file in your tools (KiCad, standard PLM/ERP formats), under systematic NDA.
This positioning is based on 7 years of reverse engineering and component, board, and system cost analysis at Yole SystemPlus (RF division), expertise in electronics (RF, EMC, signal/power integrity), and a PhD in materials science. From schematic reconstruction to obsolescence audits, I transform a "black box" board into clear, usable documentation.
Typical needs: lost schematic to reconstruct · BOM to recreate · obsolete component to source or replace · definition file to produce · PCB design or review using KiCad.
