Senior🎓
Top SchoolJohn Chapin is a Managing Software Engineer with 11+ years of experience leading development, delivery, and rescue of web-based applications across industries including healthcare, e-commerce, and government. He emphasizes disciplined software engineering over ad-hoc coding—defining needs, analyzing data, setting realistic goals, and iterating with measurable improvement—often translating weekly sprint feedback into project management and business cycles. His background spans hands-on work in Ruby on Rails, PHP, C#, Objective-C and Java, plus building virtualized infrastructures and introducing QA and automated testing practices. Notable projects include a secure health-information exchange with 86% test coverage and the first online vehicle registration renewal system for a major municipal government. He combines technical depth with procedural rigor, making him as comfortable tuning legacy systems as steering cross-functional delivery.
