MERN stack developer. Building production-ready
boilerplates and developer tools. Passionate about crafting elegant solutions to complex problems.
Built this after rebuilding auth from scratch on seven different MERN projects — MERN Auth Starter ($79). Here's what I built
After rebuilding authentication from scratch on seven different MERN projects, I finally packaged it properly.
The feature I'm most proud of: refresh token reuse detection. If a stolen token gets replayed, the entire session wipes immediately. Most auth
tutorials never mention this exists.
Also built a demo mode — full auth flow with zero external services. No Resend account needed to test.
