About

Every developer I know is asking the same question right now: "What does my career look like in 3 years?" I've been in software for over 20 years. I survived the dotcom fallout, the mobile revolution, the cloud migration, and the JavaScript framework wars. I've been an individual contributor, a developer advocate, and now I lead the content team at Auth0 (Okta), helping millions of developers learn about identity and security. But this AI shift feels different. Not because of the technology itself, because of how fast it's changing what companies expect from developers. And I'll be honest: it's what pushed me to start writing publicly. The career advice I wish I'd had doesn't exist for experienced developers. Everything is either "learn Python in 30 days" or "AI will take all jobs." Neither is actually helpful. So I write about the messy middle. How to make career decisions when the ground is shifting. What skills genuinely matter as AI reshapes dev work. How to build a career that survives multiple tech cycles, not just the current one. If you're a developer or engineering leader with 5+ years of experience trying to figure out your next move, follow along. I write The Long Commit, a newsletter for engineers playing the long game.
