Sebastian is the most difficult type of programmer to find, any challenge that I have asked him he has been able to carry out, where other programmers have asked me for double the time and even more people to work on the project. Sebastian has the mindset that anything is possible, and he will give more than 100% of himself to achieve the best results with his projects, this happened every time he worked with us.

Sebastian came to us looking for an informational interview on how to find a role, we instead gave him an opportunity to suggest edits on our own website and he immediately showed value. Without instruction from us, he set up a project management tool to log all the issues he saw as potential problems, owned and thoughtfully explained each one via the PM tool or over video calls. He assigned priority and gave status updates all along the way. He worked through enhancements, security issues, plug-ins and more to create a more succinct website all self-managed and very timely. From an agency perspective, he is a self starter who successfully owned and managed everything we threw at him with flying colors. We are continuing to work with him and highly recommend him to anyone looking to grow their creative team.
