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.

My passion is to make APIs more impactful and developer-friendly, which is why I created the API Product Manager Fundamentals course: to share my lessons learned and help Product Managers fast-track their careers.

Join me to gain practical insights, avoid common pitfalls, and learn how to deliver API Products that enable great user experiences—without repeating the mistakes I’ve already made along the way.
