Jon Herron is a founding software engineer with nine years of professional experience building production systems across startups and Fortune 500s, currently leading engineering at Sartography. He brings deep full-stack chops—from low-level languages and cross-platform development to web stacks (JavaScript, PHP, .NET) and both SQL and NoSQL data stores—paired with strong architecture, debugging, and unit-testing discipline. At Yahoo he contributed to high-profile consumer products including the company’s first native iOS mail client, and more recently he implemented service-task extensibility in the open-source SpiffWorkflow Python engine. Comfortable in Windows and Linux environments, Jon blends pragmatic engineering with careful specification and security awareness. Based in Marietta, Georgia, he favors practical refactors and clean code, often surfacing non-obvious improvements like delegate-based execution hooks to make systems more extensible.
