A committed team-builder, Rafa taught me (and many other teammates) how to engage successfully with technical customers and deliver a top-class experience with every interaction. He consistently employs his broad technical expertise across backend and web technologies to troubleshoot, understand, and resolve the deepest cross-platform bugs. This dogged determination to identify and obviate complex technical challenges is matched by an empathetic approach to communication for internal and external stakeholders. Rafa is a master of defusing tense situations and conveying critical information calmly as he moves the situation towards resolution. Countless times I have watched Rafa turn a frustrated customer into a dedicated advocate; I could not recommend Rafa more highly.

I worked with Rafa during my early days at Mapbox. In a fast pace environment, he shined as an emphatic leader. Always ready to pair with teammate or experiment with a new process to improve the team's workflow, Rafa leads by example. I have always appreciated how Rafa handles a new challenge with a level head and optimism. I am grateful for all that I've learned from Rafa.

Rafa and I have worked side-by-side helping Mapbox customers understand our product and work through technical problems. The nature of the work has changed, but Rafa's approach hasn't. He's one of the most empathetic, encouraging, and relentlessly helpful people I've ever worked with. Helping people succeed is the north star of everything he does, and it shows in the work he does ever day at Mapbox. I will forever be grateful for the careful, thoughtful, and thorough help Rafa provided me when I was getting started. And I know the dozens of customers he helps every day feel the same.

- Dan Swick, Frontend Platform Engineer at Mapbox

Not a day passes during which I'm not amazed by Rafa's institutional knowledge of the Mapbox universe. He's a walking encyclopedia of our products and the history behind them - why where they built, what was unique about them, and which challenges did they help users solve? Rafa dives deep to troubleshoot technical bugs and can succinctly communicate customer needs back to product teams. I'm honored to work alongside @geografa to ensure a positive experience for all 800,000 Mapbox users - thanks Rafa!
