Summary
David Harkness is a Senior Software Developer with 11 years of professional experience building Ruby on Rails backends and Angular front-ends, currently focused on platform and reliability work at Pinion. He has a strong track record in SaaS and marketing technology from roles at Terminus and CrystalCommerce and has shipped features for high-profile clients while working on social and commerce platforms earlier in his career. Comfortable across the stack, David combines Rails expertise with SRE-minded practices, PostgreSQL, Linux tooling and integration of services like VOIP and mail systems. He thrives in agile, collaborative environments and has repeatedly moved between consultancy and product teams, which honed his ability to quickly scope and deliver pragmatic solutions. Based in Alpharetta, GA, he pairs hands-on coding with system-level thinking—often tackling messy integrations and deployment reliability that aren’t obvious from a job title alone.
