About Renan W. Spatin

Technology Strategist, AI-First Architect, and Bachelor of Laws focused on resilient systems, distributed architecture, and disciplined leadership.

Technology Strategist · AI-First Architect · Bachelor of Laws

I'm a Technology Strategist, AI-First Architect, and Bachelor of Laws with 7+ years shipping systems that solve real-world complexity.

My practice is centered on Systemic Efficiency: using AI and deep engineering to optimize operations in high-precision sectors like Law, Medicine, Finance, and Engineering.

Having worked with major institutions and developed my own products, I've gained a cross-industry vision that allows me to identify where technology and AI create immediate and sustainable value.

I am driven by discipline and systemic thinking. I hold a Law degree, I'm a BJJ blue belt, and I look to philosophy for the clarity to lead projects where technology serves as a mean for human excellence.

I believe systems should be intelligent by design and robust by nature. I operate independent projects and pursue an MBA at FGV to continuously refine business strategy applied to technology.

off the keyboard§ 02

Off the keyboard: I train jiu-jitsu (blue belt), play guitar, and play tennis as an honest beginner. I'm Catholic - comexaltai.com isn't a client project, it's community.

Two cats at home. An NFC biochip I've had implanted in my hand for a few years (works better than you'd think). And photography when time allows - the photos end up at @rwinterlens.
