Senior🎓
Top SchoolMark Penner is a full-stack software engineer with 12 years of experience building web applications and services, currently contributing to YouTube at Google while also serving as CTO of a startup focused on the limo and partybus industry. He brings hands-on expertise across backend systems (PHP, Python/Django, MySQL), front-end design, and server operations—skills honed from building sites from the ground up and managing production infrastructure. His background includes senior development roles where he paired feature delivery with mentoring and innovation, plus early research work in real-time human action recognition. Comfortable shifting between startup grit and large-scale engineering, he blends product sensibility with technical craftsmanship. Based in San Bruno, California, he’s equally at home shipping user-facing features and running the technical side of a niche transportation business. An eye for practical design and a history of end-to-end ownership set him apart from specialists who focus on only one layer of the stack.
