Spenser Hale

Lead Software Engineer

Lead software engineer with over a decade of experience using technology for meaningful impact. My approach is rooted in pragmatism: I choose the optimal tools and methodologies while considering resources and limitations to determine the best fit for each project. I have led product development and infrastructure rearchitecting from single closet servers with a few dozen clients to a multi-cloud deployment serving millions of patients. I am looking to solve new business problems with software.
