Erik V. · DataRoute BV

February 2026

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.

Nadia F. · ClearLedger Co.

December 2025

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.

Sam T. · Stacklane Ltd.

October 2025

Solid data engineer with great technical knowledge. He was very thorough — maybe more thorough than our timeline required at times — but the quality of the output was excellent.
