With over 17 years in software engineering and several years in leadership and management, I've worked with various companies to deliver tech solutions that matter. My approach is straightforward: Agility and transparency are key to successful projects. Outside of work, I lead a Dungeons and Dragons group and enjoy photography, blending creativity with technology.

I'm passionate about automated testing and improving developer experiences and productivity. I have a fable for the Elixir programming language. Currently, I'm exploring AI and Machine Learning to enhance my skill set. Simply put, I'm a developer with leadership experience committed to creating impactful software and keeping up with technology trends to offer the best solutions.
