I make APIs easy to love.

Developer Relations engineer with eight years of DevRel experience and a background in full stack development. I build the integrations, client libraries, docs, and content that get developers from first call to working app.

About

I started my career supporting customers on an email delivery platform, then spent five years as a software developer building customer-facing web apps with TypeScript, AngularJS, and .NET. Since 2018 I've worked in Developer Relations, and that background shapes how I work: I want clear docs, predictable APIs, and examples that actually run, because I've been the developer who needed them.

Most recently I was Lead Developer Relations Engineer at ActiveCampaign, where I helped grow the integration ecosystem from 200 to more than 1,000 integrations and was the primary developer for most of the AI connectors on the ActiveIntelligence platform. Before that I led developer experience at SocketLabs, owning the API reference, client libraries in six languages, and the developer content strategy.
