Who this is for:
You’ve built and shipped products solo or with small teams
You’re crypto-native and enjoy exploring new tools/protocols
You’re fast, self-driven, and prefer ownership to micromanagement
You write clean code but iterate quickly
What Success Looks Like (First 60 Days)
Launch 1–2 working products with CMS and frontend live
Build automation for token sourcing + database updates
Deliver clean UIs with fast-loading pages and working filters
Support backend tools for campaign dashboards or scraping
Details
