What People Say About Me

“I had the opportunity to work with Mateo at VieCure. We needed a team member with strong front-end skills who could speed up our product development. Mateo fit the bill perfectly. He got up to speed within 2 weeks and contributed to a key feature. Mateo is more than a front-end developer, he is an all-rounder - promoting best practices, team player, user experience designer, visionary, passionate, and pragmatic. It was great to see someone apply user empathy and user-centric design. Mateo is the person you want on your team if you want to make a difference and increase the adoption of your product. I strongly endorse him.”
Ramesh Peesapaty
VP of Technology, VieCure
“It is a constant tug-of-war between keeping development costs down by hiring junior developers from boot camps or other sources and the need to produce quality code. This is where a lead developer earns his/her salary. It is so important to have an experienced UI/UX developer that can lead and mentor the junior developers on staff. Mateo is such a person. I worked with Mateo on a project that had been poorly designed and developed by a group of junior developers. Mateo is a professional driven to produce the best product that he can while motivating the junior developers under him to learn and excel, as well. I hope our paths cross again soon.”
Todd Nash
Software Engineering Manager
“Mateo always brings great positive energy to our daily stand-ups. I’m glad to have had an opportunity to work with an experienced senior developer like him on the team, whose contributions have immensely improved the team’s performance. Mateo has always been very proactive in acknowledging the work of his colleagues, identifying gaps or improvements in the process, and wearing multiple hats to help the team wherever needed. His initiative to streamline and improve the release management process is one such example that has hugely eased the work of the developers on the team. Thank you, Mateo, for guiding the team through your experience and contributions.”
Swetha Batta
Technical PM, Senior Software Engineer, BillGO
“Outstanding frontend developer and UX designer is what comes to mind when I think about Mateo. I’ve had the pleasure of working with Mateo during which we worked together on a project where he was responsible for the frontend development and design. I was impressed with Mateo’s meticulous job of improving the product and codebase while iterating for the future.  Mateo would be a true asset for any positions requiring an improved frontend and user experience. I would recommend Mateo.”
Joshua Hendricks
Senior Architect, RefiJet
“Mateo was a Senior Software Engineer working on a team that delivered a set of user interface widgets that enabled BillGO's Bill Pay functionality in our clients' web-based applications. It is a complicated environment using some unique tools, and Mateo came up to speed quickly. He is a very capable developer with a good eye for design and usability. He had many ideas for how to improve our development processes, our code and our product. He's opinionated (in a good way!) but balances that with friendliness, flexibility and agreeableness. Any team that takes full advantage of Mateo's skills in UX and front-end development will be lucky to have him!”
Patrick Conant
VP of Engineering, BillGO
“As a product manager, working with Mateo is a dream. He brings a wealth of knowledge in both front end web development and UX design. He is excellent at collaborating rapidly through ideas, and always brings a fresh perspective by consistently being up to date on the latest best practices and design trends. Anybody working with Mateo can expect to move much quicker and end up with a better product than before. This allows you to focus on everything else a PM needs to focus on, and trust that the product is in good hands..”
