Thomas H is a security-minded software engineer with 10 years of experience based in Strasbourg, France, holding an OSCP certification and a background in web development and pentesting. He has worked as a pentester at SecuLabs and as a web developer at Malt, and trained through intensive programs at The Hacking Project and 42. A consistent open-source contributor, Thomas focuses on back-end engineering for offensive security tools—leading fixes and feature work on projects like GHunt and holehe and enabling hash-cracking workflows in Google Colab with penglab. His work blends practical tooling (chromedriver fixes, Google Photos bypasses, module refactors) with automation and performance improvements, reflecting a hands-on, defensive-offensive skill set. Always learning and documenting through the hideandsec team blog, he brings a pragmatic approach to security engineering that surfaces subtle operational issues before they become incidents.
