Marcus picked up React in 2017 and has been writing it professionally ever since. Five years at Stripe on the Dashboard team, where he led the migration of the billing UI off a legacy webpack 4 setup onto Next.js with module federation for the embedded merchant components. He shipped the first internal RSC prototype there in late 2023, which mostly worked. Now he's a staff engineer at a logistics startup in Austin, owning the customer-facing Next.js app and the design system that backs it. He spends a disproportionate amount of time thinking about route group conventions, parallel routes for modal UX, and why next/image keeps surprising people on Cloudflare's image resizing. His writing favors annotated code over prose. Seven years of React, two of those deep in App Router land.
