VP of Product Engineering

"The thing that really sold us on mabl was its ability to integrate with our engineering workflow. Engineers can be running mabl tests, not just the unit tests, not just their integration tests, but actual mabl tests as part of their workflow. We think it's going to have an incredibly important impact on the future growth of Stack Overflow."
