Summary
👤
Senior🎓
Top SchoolMark Valdez is a founder and seasoned software architect with 16 years of experience building 0-to-1 SaaS products and leading full-stack engineering across startups and mid-size teams. Based in San Francisco, he blends hands-on implementation (React, TypeScript, Rails, Node, AWS) with architectural design for microservices, analytics pipelines, and low-latency systems. He has repeatedly shipped greenfield platforms—from marketing and ad-analytics SaaS to encryption-as-a-service and mental healthcare applications—and has experience hiring and mentoring engineers. His background includes teaching computer science at university level and building custom infrastructure (tracking pixels, payment systems, custom email servers) that reveal a pragmatic focus on operational reliability. Currently running a stealth AI startup while contributing senior engineering leadership at Upright Labs, he pairs entrepreneurial grit with deep systems knowledge. Outside work he describes himself simply as a programmer and gamer, a hint at a curiosity-driven, hands-on approach to problem solving.
