My name is Juan de Souza, a 25-year-old entrepreneur, investor, blogger, and streamer. My journey in business began at the age of 10, leveraging a dial-up internet connection in Brazil to start my first venture. Currently, I reside in Porto, Portugal, where I have been based since 2025.
Founded on January 23, 2016, at the age of 16 when I was still in high school in Brazil, TFX emerged from a vision of turning technological challenges into opportunities. The company quickly stood out for delivering high-quality, strategically designed technological solutions that meet the specific needs of each client through efficient segmentation. Today, headquartered in the state of Florida, USA, TFX has significantly expanded its reach and now serves clients in North America, Latin America, and Europe.
ArcaneByte Games was born from a lifelong passion for video games and a desire to contribute something unique to the world of interactive entertainment. My journey began with a love for storytelling, art, and technology. Inspired by the games that shaped my childhood, from classic platformers to deep, narrative-driven RPGs, I decided to merge my skills and dreams to create a game studio that would blend innovative gameplay.
QuickDevTools is a complete solution offering a vast array of tools that cater to both basic tasks, such as code formatting and validation, and more advanced functionalities, including performance analysis, security checks, and data conversion. All of this is accessible from a single online platform, eliminating the need for local software. It's 100% free and doesn't store any data.
Coliseu Geek was born from my enduring passion for these fascinating fields and my conviction that relevant information about technology, games, and cinema. Our commitment is to deliver content that informs, entertains, and inspires audiences around the world, regardless of the language they speak. The website was discontinued in August 2024.
I discontinued some projects such as Sonia Ideias - which was a blog with the objective of sharing insights, Vanna AI - which was my artificial intelligence with limitations that later became TFX AI and a TFX product, Blenner - a dedicated server in cloud computing when it was still something new and restricted, which later became TFX Cloud, and some other projects.
Instead of focusing on preparing for university entrance exams, I chose to take a step forward in building my professional future. During my last year of high school, I started developing my first UX/UI prototypes and worked hard on preparing my company's Business Plan during my free time in the classroom. This decision represented a paradigm shift in my trajectory, directing all my focus to my dream since I was 10 years old.
Colégio Stockler was known for its dedication to educational excellence and the holistic development of students, and this reputation was fully confirmed during my time there. Furthermore, it was in my second year of high school that I discovered a security flaw in the student grade entry system, an incident that provided me with a valuable learning opportunity.
Colégio ICT has an educational proposal focused on Technical Education, which turned out to be an approach that did not align with my profile at the time. My difficulty in adapting to the school's methodology and structure ended up negatively impacting my involvement and grades at school.
Colégio Themis de Almeida Vieira is a public school that, despite the challenges that many public institutions face, offered me a very positive educational experience. During this time, I have benefited from a dedicated team of educators who have strived to provide an enriching learning environment.
Escola Municipal Bahia is a notable example of how the quality of education is not necessarily linked to the status of an institution, but rather to the commitment of its educators and the dedication of students. My experience at this public school was truly incredible and one of the best possible.
The Renarice Educational Institute not only gave me a solid start in my education but also contributed significantly to my personal development. From an early age, I learned core values that shaped my worldview and approach to life. The values of respect, empathy, and responsibility were emphasized at Instituto Educacional Renarice, and these principles have been essential pillars in my life ever since.
