I've been in the tech industry for +20 years now, and I've had a lot of amazing experiences. One of my favorite moments was when I created the scraping engine for Rethink X Social. It was a challenge on many levels—not only did it require me to learn new skills and processes, but also it forced me to step out of my comfort zone and take some risks. And it was worth it. Not only did I learn so much from this experience, but now we have an incredible infrastructure that's allowing the company to serve its customers in ways they never thought possible. I'm a passionate and curious engineer, always trying to learn and grow. I strongly believe in teamwork so I always try to help others too, in any available way (mentoring, lecturing, pair programming, etc) I enjoy problem solving and new challenges, and as part of that I'm currently looking for the next step in my professional development.
