I fully understand you need a disciplined implementer, not a creative developer — your codebase is ready, and you need someone to assemble it exactly as designed with zero drift. I've done exactly this type of assembly work with Node.js/Express backends and React frontends, including wiring up wallet systems, revenue ledgers, and dashboard panels with Chart.js. My approach is straightforward: I'll spin up your backend modules and platform endpoints first, connect the SQLite/Postgres schema as-provided, then assemble the React dashboard with the AI insights and platform health panels, and finally test every endpoint via Postman — transfers, charges, payouts, and revenue events. No redesigns, no "improvements," just your code running exactly as intended. I can start immediately.
