    Hello! Thank you for viewing my profile, I introduce myself, my name is Thomas and I am a young man with a vocation for computers since my childhood. At the age of 14 I started doing research and small projects by consuming a lot of online content about the languages and technologies that caught my attention. My first personal project was a proxy server publishing website. In which I used PHP, HTML/CSS/JS (bootstrap) and Python. Being used PHP and HTML/CSS/JSS for the UI of the clients and Python for the scraping and checking of the proxy servers. After 2 years doing small projects for pure self-interest, at the age of 16 I discovered FiveM, a modification of the popular video game GTA V, which allowed to program modifications to the game experience. Thanks to this discovery I learned Lua and the importance of optimization. I also discovered netfilter and the power of iptables after creating FiveM servers and being a victim of numerous DDoS attacks. At the age of 18, I started with a friend an Anti-DDoS hosting service in the face of a wave of massive attacks on FiveM servers. Since then I have been fascinated by computer security and related applications such as: NGINX, HaProxy, etc... Which aim to create resilient, scalable and highly available systems. I also discovered several flaws in FiveM source code, reporting them and helping to fix them. Of course during all these years I have been studying in my home country, Spain. Thanks for reading this far! And last but not least, here I list the languages and technologies I know along with the level of knowledge I have of them. Languages: * Python (High) * JavaScript/TypeScript (High) * Lua (High) * PHP (Medium-High) * GoLang (Medium-High) * C/C++ (Medium) Technologies: * NGINX (Medium-High) - I consider myself pretty skilled with NGINX but I haven't gotten to use their enterprise version so I wouldn't want to overqualify myself. I have also used Lua alongside NGINX. * HaProxy (Medium) * Docker (Medium-High) * Kubernetes (Medium) * MongoDB (High) * RedisDB (High) * pfSense/OPNsense (High) * PostgreSQL (Medium-High) * MySQL (High) * Let's Encrypt (SSL) I also understand that the absence of associated projects may generate mistrust and I understand that. Most of my projects are not public for personal reasons or for use in private systems.
