About API Evangelist
API Evangelist has worked for the last 15 years to make sense of the technology, business, and politics of APIs, profiling public and private APIs and distilling down knowledge into a regular cadence of API storytelling, and weekly knowledge building sessions focused on schema, APIs, governance, operations, change, and evangelism. API Evangelist is committed to helping your teams focus on the fundamentals of APIs, while also working with you to make sense of the leading edge of APIs, and where all of this is going.
