Launching software and AI products
for Founders and Teams
Tell me what you're buildingAbout Me
Hi there! I'm João, a Product Engineer with 8+ years of experience helping businesses solve real problems through technology. Originally from Portugal and based in the Netherlands, I specialize in Ruby on Rails, Next.js, React, AWS, and practical AI/LLM integrations.
I work with founders and teams who want to shape an idea into a real product. Whether the challenge is a new SaaS, product improvements, or AI features that actually help users, I bring the technical judgment and hands-on implementation to move it forward.
