Nestor Castillo is a Senior Software Engineer at Equifax at Equifax. He possess expertise in ruby on rails, ruby, javascript, css3, sql and 21 more skills. Colleagues describe him as "I had the pleasure of working closely with Nestor at DealerHQ. Nestor is certainly someone I highly recommend without hesitation. From a technical standpoint, he is solid and played an instrumental role in successfully rewriting our platform in Rails, creating and deploying our Chrome extension and deploying releases to both staging and production environments. From a management standpoint, as our team expanded, he helped manage and direct the efforts of a junior engineer, providing both mentorship and guidance. However the two qualities I appreciated most about Nestor was his work ethic and flexibility. Knowing that you can depend on someone to both 1) work hard to get the job done (often with minimal oversight) and 2) understand at times radical shifts in focus are necessary for the business, are incredibly valuable traits. I am a huge fan of Nestor's and I look forward to seeing all his future successes." and "I had the pleasure of working with Nestor during my time with Izea. It was my first position that involved working on a Rails app, and my success there was due, in no small part to Nestor's commitment to leveling up the skills of everyone around him. He organized a book club that met weekly and discussed books on a variety of programming concepts. He also ran a bi-monthly Ruby 'Dojo' that forced us to think outside the box in tackling common programming exercises using test-driven-development. More than anything, Nestor is very good at explaining things and is committed to making time for anyone who needs his help. Whenever I'd go to him with the question 'Can you give me a hand with something?' the answer would be 'Yes.' 100% of the time. And he would make sure that I fully understood the problem and the solution before I returned to my desk. His ability to communicate complex programming concepts in simple language is one of his greatest strengths. All in all, I'd work with Nestor again in a heartbeat. And if I were in a position to hire a rails developer, he would be one of the first people I call."
