About Joaquim
I am an engineer specializing in artificial intelligence, signal processing, and Python development. My professional journey includes:
‣ AI Engineering & Python Development (Current)
— Providing Python development services.
— Offering AI engineering services.
‣ AI/IT Consulting (Current)
— Assisting businesses in integrating AI into their operations.
— Conducting independent, tech-focused assessments to identify system-wide challenges and implement effective solutions.
‣ Academia
— Conducted research in deep learning, learning theory, and video compression, resulting in the publication of seven works with over 400 citations.
‣ Startups
— Co-founded Radiobooks, a project that leverages AI text-to-speech technology to make more books accessible in audio format.
Outside the scope of my scientific expertise, I dedicate my time to exploring philosophy, psychology, meditation, and ethics. I find joy in tackling problems holistically, drawing inspiration from both ancient and modern wisdom, and considering the entire pipeline from philosophical and scientific inquiry to practical application. I appreciate engaging in thoughtful discussions, being exposed to different points of view, and—when suitable—sharing the little I know with others.
