About Emmanuel Paraskakis
I help teams build what agents want.
I’m Emmanuel, an entrepreneur, product management executive, and consultant at Level 250 with over 15 years of experience shaping API products.
I’ve led large API programs in fintech for Verisk, Moody’s, and Precisely, and served as VP of Product for some of the world’s most influential API tools—like API Blueprint at Apiary (550,000+ APIs), Oracle’s first Cloud-Native API Gateway, and Swagger at SmartBear (750,000+ APIs).
Over the years, I’ve consulted with everyone from Fortune 500 CEOs to startup founders, engaging with thousands of API providers and consumers to help them build winning products and exceptional developer experiences.
Today I help product leaders, PMs, engineers, and architects make those products work for a new kind of user: the AI agent. That means deciding what agents actually need, choosing the right mix of APIs, MCP, CLI, and Skills, and turning the answer into something your team can ship.

Emmanuel is super knowledgeable on all things APIs. He also is innovative, thinking about MCP and how to leverage AI first workflows to build great APIs. Finally he cares about his learners. He met me for a pre-course zoom, stayed after class to chat extra with me when I had questions, and had a 100% answer completion rate during the class. I highly recommend taking a class with Emmanuel if you have the opportunity!
