Tim Sullivan is a Principal Software Engineer with 14 years of experience building high-performance .NET systems and cloud-native integrations across Azure and AWS. He has deep expertise in C#, Web API, MVC, WCF, and WPF, and a track record of improving system performance—most recently leading an async redesign that boosted throughput by over 50% on a Real-Time Prescription Benefit platform. Tim pairs backend rigor (custom workflow engines, RabbitMQ, high-volume XML processing) with front-end skills in Angular and JavaScript, and has modernized legacy stacks through migrations and CI/CD automation. He’s comfortable bridging product and engineering, having designed imaging/indexing solutions, mentored teams, and led cross-functional architecture efforts. Based in the Twin Cities, he also brings an unusual mix of graphics/engine experience (Unity3D, OpenGL) that informs pragmatic, performance-conscious designs.
