Senior Software Engineer

I’m a restless developer with 10+ years of full-time experience. I enjoy new challenges and varied projects that keep me on my toes. I draw inspiration from my Master's degree background in geophysics to break down complex problems and find clean and effective solutions. I’ve been praised before for going the extra mile and take pride in delivering neat code that is optimized for maximum readability and scalability. I thrive in the workplace when I can find a dynamic environment that fosters teamwork and encourages me to learn and grow every day both personally and professionally. My passions, besides programming, are playing the guitar, playing football and training for my next marathon.
