My name is Matthew Czubakowski, and welcome to my personal website.

I'm a software engineer located in San Francisco. I graduated from Caltech in 2009.

By day, I develop test automation for Xero in San Francisco. I have a broad skillset with experience in software development, mixed-signal ASIC design, systems engineering, and circuit design and test.

By night, I experiment with web design, game development, music, and video game livestreaming.

Feel free to contact me through social media. I'm easiest to get a hold of through e-mail, Twitter, and Facebook.
