Paul Gressier

You may call me a Geek! I have been writing code since college both for PCs and smartphones and soon became the savior of family and friends who had lost their data or got their gear infected. Thus, I naturally oriented my studies and my career on this domain with a strong prevalence for security. As presented in the dedicated sections, I perform development missions as well as security missions. Web pentests, network, assistance, crises interventions, development of a network recon app... in depth presentation is done in the respective sections. Thereby, I will be happy to assist you in your projects as a consultant or developer for short or longer missions.
