Senior🎓
Top SchoolToby Osbourn is a seasoned Freelance Developer and interim CTO with 14 years of experience leading engineering teams across fintech, public sector, events, and agency environments. He combines hands-on Ruby on Rails expertise—evidenced by contributions to the popular AssetSync project—with a strong track record of technical leadership, team building, and technical writing.

He’s equally at home shipping code, documenting technical decisions for non-technical audiences, and stepping into short-term CTO roles to stabilise delivery and processes. Based in Belfast, he runs Tosbourn Ltd and is available for remote engagements that need pragmatic architecture, developer coaching, and durable engineering.
