Engineering that delivers. Modern tools, measurable results.
Florianopolis, Brazil
Modern craft.
Reliable delivery.
I build and automate — turning complex technical challenges into clean, reliable systems. Over 13 years of hands-on engineering means I already know the pitfalls, the shortcuts that don't hold, and the approaches that scale. I work with precision and move fast without introducing technical debt.
Businesses that work with me get a technical partner who communicates clearly, thinks ahead, and delivers. Whether that means modernizing a legacy stack, integrating AI to cut manual overhead, or architecting a new product from scratch — I bring the experience and discipline that quality-focused teams rely on.
