I'm the guy who had the guts to walk away, in 2024, from a 10-year career in software engineering — working for companies in Brazil, the United States and Portugal — to study LLMs and AI, and to build a business out of my own projects.
You might be thinking:
Hmm, so you failed and now you're looking for a job?
Yes, that's true. I coded too much and did too little marketing. But I learned a lot.
If that caught your attention, great! It's the honest truth. My name is Marcus Vinícius de Vasconcelos Filho, and I want to get back into the software development market.
I hold a degree in Systems Analysis and Development (ADS) from IFPB, and I recently passed a public examination at IFPB for a teaching position in Basic, Technical and Technological Education (EBTT). I didn't land one of the 8 openings, but I'm on the reserve list (18th place), and I'll possibly be called up in 2028 or later. To brag a little: I came in first on the objective exam! What sank me was the lack of academic career credentials — hence the 18th spot.
Until then, I want to make the most of my time in the market, especially building solutions with AI models, and with the development technologies and infrastructure I already have plenty of experience in: Node.js, Docker, Python, Angular, React, Cloudflare, AWS, MongoDB, PostgreSQL, etc, etc.
(Just to be clear, I'm open to new technologies — I'm an advanced Claude Code user and I pick up quickly any technology I don't know or haven't worked with yet.)
A webapp that's a free tool for recording and downloading X Twitter Spaces. It uses the OpenAI Whisper and Qwen3.8 27B models for voice-to-text, summarization and metadata creation for the Rexpaces channel on YouTube.
Every video on the channel was generated by the tools I built.
A short-form video editor webapp (shorts, reels) for content creators who want an app that's fast, easy and flexible to use. No installation required.
I compiled all the dozens of UFO release PDFs declassified by the US government and extracted organized information using OCR techniques with Python. The site is a hobby; the goal is to present the information in an organized way for ufology researchers. I used AI prompting to summarize the documents and extract keywords.
