“Data is the new oil. It’s valuable, but if unrefined, it cannot really be used.”

Clive Humby, British mathematician and co-founder of dunnhumby


I can not stress this enough: on top of being an excellent professional and an expert on his field, he is an incredible kind and respectful person. He was always committed to perform at his best and always proposing beyond expectations, offering an alternative view for every piece of work delivered. Although sometimes (if not always) clients can be undecided, he managed situations respectfully, crafting with finesse the deliverables to match their expectations. I would definitely work with Leonel again.

Leonel redefined my concept of willingness. I have never before seen such a drive and passion to pursue results, regardless of the circumstances and finding an oportunity in every obstacle. Wining the client's hearts and applause at every step, and his teammate's cheer as well, Leonel is one of those people who not only delivers, but also makes the work environment more pleasant to everyone. Loved working with him every time, and looking forward for the next time it happens
