I’m Emmanuel, 3x VP Product, now a founder at Level 250.

If you built or used APIs in the past 15 years, chances are you’ve used one of my products:

I’ve led some of the most influential API tools: Apiary (550,000+ APIs), Swagger (750,000+ APIs) and Oracle’s first Cloud-Native API Gateway. Before that, I built large B2B API programs at Verisk, Moody’s, and Precisely.

Today, I advise Fortune 500 CEOs and AI-forward startup founders on API Strategy, Developer Experience, MCP products, and AI agent readiness.

I'm also a member of OpenAPI and a featured speaker at apidays and other global technology conferences.

My passion is helping others build products, which is why I also teach on Maven: to share my lessons learned and help Product Managers and Engineers fast-track their careers.

I am a product leader focused on building and scaling digital platforms that drive revenue, unlock new business models, and power global commerce.

Over the past 15+ years across e-commerce, logistics, and fintech, I’ve worked at the intersection of product, technology, and business—leading platforms that operate at global scale. At FedEx, I lead the Visibility portfolio, powering shipment tracking and intelligence capabilities used by global supply chains and e-commerce platforms, processing over 1 billion transactions every day.

I’ve led the evolution of FedEx’s API ecosystem end-to-end—from product strategy to global go-to-market. This includes rolling out the developer platform across 200+ countries and building GTM approaches tailored to different customer segments supporting over $20B in business value across FedEx services, with 40% CAGR.

One of my key contributions has been building FedEx’s Visibility API, Real Time visibility, commercialization approach from the ground up—shifting APIs into revenue-generating products. The tracking portfolio evolved from a cost center into a profitable, data-driven business, now generating 8-figure ARR with over 100 million billable transactions per month.
