How I work with AI

Wait, what?

What people say
about me

George A. Bolea

Lead Product Designer at Pago App

September 16, 2026, George worked with Robert on the same team

I worked with Robert at Pago across several of our web products in different domains, different levels of complexity and Robert came through every time. Features arrived complete and thought through, including the unglamorous details that decide whether something feels finished. What stood out most was how easy Robert was to work with: clear communication, feedback taken without ego and returned improved, and work delivered when promised. Robert is also one of the more effective people I've seen at using AI tools as a real part of a delivery workflow and not as a gimmick, but with the judgement to know when the output is right and when it isn't. Any team would be lucky to have Robert.

He brings a thoughtful, quality-first mindset to development, and he raises the bar for the team through both execution and attention to detail. Robert is also an AI enthusiast and a real advocate for using AI in practical, value-adding ways.

Robert was my teammate at Cloud Innovations. We worked together on two big projects in the company. I ended getting a lot of information from Robert because he was always there to help. He has a lot of patience and is very skilled in the frontend development department. He's a master of the CSS and works really really good with JS and JS related frameworks. He accomplished to learn React on a very short period and now I can say he's proficient with React. The best asset of Robert is that he's very friendly and made the work more enjoyable. His strengths: - coding - mentorship - friendliness
