“Luis is the best data engineer I've hired — and I've hired many. He understood our domain quickly, asked the right questions, delivered clean code with real tests, and wrote documentation that our team can actually maintain.”

“Luis built our entire data infrastructure from scratch in 10 weeks. He was transparent throughout, flagged risks early, and delivered something far more robust than we expected.”
