Top SchoolDaniel Schaffer is a Staff Software Engineer based in Northborough, MA, with two decades of engineering experience and 11 years in senior roles building scalable web and platform systems.

At Instawork he continues to drive cross-functional initiatives and mentor teams, bringing hands-on expertise in durable backend workflows, automation, and deployment tooling. Daniel has a track record of cost- and performance-focused engineering (including a major CloudFront migration that cut OPEX and improved render times) and a habit of building reusable developer tools that simplify complex workflows. Self-taught and pragmatic, he bridges legacy Windows/.NET ecosystems and modern platform engineering practices. Colleagues rely on him for pragmatic architecture choices that balance immediate product needs with long-term maintainability.
