Hi, I'm Zachary.

I'm a Developer Experience Engineer at WorkOS. Before that I did developer-education and staff developer- advocacy work at Pinecone, senior engineering at Cloudflare, and tech-lead work at Gruntwork. 14 years in production as a full-stack engineer — databases, backends, middleware, and frontends — with a deep love for infrastructure-as-code and cloud systems. I'll happily write the migration, the API, the React, and the Terraform module that deploys it.

I offer specialized AI engineering services focused on production-ready Next.js apps with vector-database integration. If your team was handed an LLM and a deadline, I can help you ship a RAG pipeline, an agent harness, or the evals that tell you whether any of it works.

I've been writing online since I was fifteen. The form has changed — blogs, newsletters, this site — but the reason hasn't. Writing is the only way I know to verify that I actually understand something. The Modern Coding letter is read by 5,000+ engineers and is where most of what I publish ends up first.
