Darren Hoehna is a software engineer with 11 years of experience who blends deep systems-level Windows development with entrepreneurial instincts, currently contributing to Microsoft's high-profile Windows App SDK and DevHome projects. He specializes in environment management and runtime integration—work that connects tiny, delicate code changes to large upstream and downstream systems—and has shipped features used across Windows desktop apps. Darren pairs backend C++/.NET expertise and big-data pipeline experience (Spark/Scala, HDInsight) with practical tooling that reduces deployment friction. An entrepreneur and creator, he streams and makes educational Haskell videos under ThatProgrammingGuy, and has launched two startups, one of which is in its infancy. Colleagues describe him as a developer with compassion who communicates well across teams and thrives in startup-like, cross-functional environments.
