What people who have worked with me say
We worked with Rubén on the evolution and maintenance of critical applications in the automotive sector. He has an uncommon ability to step into complex legacy code without breaking what already works. He has shipped on active codebases for several premium brands with the same rigor and without a single last-minute escalation. He's the kind of profile you bring in when you cannot afford to fail.
Rubén is highly committed to every project he takes on. Worth highlighting is his proactivity in spotting areas for improvement and identifying the best technical options when designing a solution.
Rubén built the shipment and consumption tracking applications for Heineken on a very tight schedule. The challenge was integrating data from multiple systems without degrading performance on the closing reports. He delivered on time, the client signed off with no issues, and it has been running in production for months without a single support intervention. Exactly what you expect from a senior contractor: he walks in, understands the context, and ships.
