Talented, open mind, data and quality driven are the words that come to my mind when I think about Miguel.
I was lucky to manage Miguel during 3 years at CarRentals.com. We worked together to make CarRentals.com booking and payment systems better, moving from a monolithic application to micro services using event driven design. We had great achievements during this time. One I remember is how Miguel changed our payment service code architecture to make new payment service providers on-boarding quick, easy and safe.
I was particularly impressed how Miguel was mentoring junior engineers within the team, he never gave up when trying to make them better engineers, always willing to share and help. He helped me to build a technically strong and quality focused team for sure.
Miguel is a fervent supporter of agile methodologies and shared his experience in a nice talk at during Expedia Group Agile Summit, another way for him to share and help others !
Miguel would be a great asset to any team.

I worked with Miguel as part of CarRentals core engineering team. Miguel is a focused person and the way he solves problem with integrity is really appreciable. I have had opportunity of working closely with Miguel on different projects and I noticed that he adheres to the processes and makes sure to deliver the code/results with good quality. It’s been a pleasure working with him.

Worked with Miguel for couple of years. He is very good at designing solutions and getting things done the right way. He is very helpful and helped me with PHP and learning the tech stack.
Miguel is great developer and teammate to work with. I have worked with him to stream the data from backend to the data platform, in which he came up with different metrics & scalable solution as well. Thinks about the system end to end and performance aspect as well.
