Madrid, Community of Madrid, Spain
Hey, I'm Felipe, a French/German Computer Science student at IE University in Madrid, and currently Co-Founder and CTO at cutting-edge startups. I bring more than half a decade of intensive experience spanning software architecture, technical leadership, and pioneering research R&D.I first worked in industrial-scale software reverse engineering - focusing on platforms like TikTok, Snapchat, and Instagra. Today, my role has evolved from hands-on coding to strategic technology leadership, team management, and innovation-driven R&D. I'm best known for founding g4f (gp4free), a non-profit initiative dedicated to democratizing access to frontier AI language models. Since its inception in March 2023, g4f rapidly scaled to over 2 million downloads and 63k+ stars on GitHub, earning recognition from major media like TechCrunch and Yahoo News, and garnering substantial strategic interest, including investment offers from industry leaders such as Baidu.I’ve co-founded multiple ventures, including ONLP Labs - a holding enterprise committed to developing, acquiring, and managing diverse SaaS projects - and Auwra, my previous CTO role. Currently, I’m leading technology for a stealth startup focused on reshaping AI-driven content creation systems, heavily reliant on innovative technical performance.Technically fluent in Python, JavaScript/Typescript, and Go - and proficient in Java, C, C++, and Assembly. I excel in full-stack infrastructure development, API design, and deployment at scale. My toolkit encompasses technologies like React.js, Next.js, Tailwind CSS, Redis, SQL, TensorFlow, and NLP fine-tuning (e.g., Llama 3.8), complemented by deep proficiency in platforms such as Vercel and Git for CI/CD automation. My reverse-engineering background involves expertise in IDA Pro, Ghidra, and Frida.As CTO, I prioritize rapidly building effective teams, quickly adapting to existing frameworks, and strategically optimizing technology infrastructures, routinely assessing teams with detailed technical audits, restructuring personnel when necessary, and filling skillset gaps through targeted hiring. My daily routine encompasses managing teams, shaping strategy, coordinating research activities, and maintaining strong communication.My career is fueled by a passion to start the next big „thing“. I approach challenges head-on, blending rigorous technical expertise with a never-give-up mindset. Whether I'm architecting APIs, reverse engineering complex systems, or leading start-up teams, I’m committed to building solutions that are as innovative as they are impactful.

Received the Academic Excellence Scholarship.
New SaaS. 10k€ MRR. AI/ML engineer. Reimagining content creation. As CTO, I built and managed a full team of around 10 engineers. I also created the architectural foundation of our tech stack, and focused on r&d of the product we are offering, as well as training our machine learning models.
Humera raised 1m € to reinvent the captcha, an industry currently monopolised by mediocre solutions. I'm taking my 5 years of experience in reverse engineering and anti-bot solutions to create the perfect scoring engine, rivaling hcapcha, recaptcha, turnstile, geetest and funcaptcha.
I wanted to decentralise the access to frontier models. I founded the non-profit software project g4f, also known as "gp4free", in march 2023, it has since then accumulated over 2 million downloads, and 63k stars. Also seen on Techcrunch and yahoo news.
