“Working with Paulo on Vellonti's e-commerce website was a very smooth experience. As a founder without a deep technical background, I often had complex ideas around the product and user experience that weren't always easy to translate into technical requirements. Paulo had a real ability to break those concepts down into clear, practical solutions and guide the implementation in a way that made everything easy to understand and iterate on.”
Simão Carvalho
Founder, Vellonti
“Paulo and I met back in college, and later we ended up working together at Noesis. We've been in the same professional journey since then, growing side by side as Full Stack Developers. Throughout that time, I've always found him easy to work with, he has a structured way of thinking, makes solid technical decisions, and communicates in a very clear and practical way.”
