John Hall is a veteran engineering leader and VP of Engineering based in Sacramento with over two decades of experience building scalable systems and high-performance teams across startups and enterprise environments. He has repeatedly taken technical organizations from zero to scale—co-founding Tradesy and growing its tech team to 30+ engineers and helping secure $30M in funding—then moving on to CTO and VP roles where he architected resilient, high-traffic infrastructures and led successful fundraising-era product builds. His hands-on background spans backend architecture, DevOps, and data systems (Linux, MySQL, Redis, ElasticSearch, AWS) as well as product-facing UI work, and he’s recently focused on AI rapid-development and SaaS proof-of-concepts. Known for shaping company culture and operational rigor, he combines strategic leadership with an engineer’s attention to uptime and performance (four nines at Cars.com). A subtle throughline in his career is translating early technical choices into long-term business velocity—enabling rapid growth while keeping systems reliable and teams autonomous.
