Full-stack Fix & Ship
I dive into your repo to reproduce, diagnose and fix issues hands-on — I deliver working patches, prioritized next steps, and clear explanations so you can keep shipping without the headache. A few areas I frequently tackle: - Fixing React / Next.js bugs (hydration issues, App Router quirks, SSR vs CSR problems) - Auth & user-sync (Clerk, NextAuth, webhooks, session flows) - Payments & subscriptions (Stripe, PayPal, Connect/payout flows, billing edge cases) - Backend & DB troubleshooting (Node, Drizzle, SQLite, API errors, performance) - Headless CMS integrations (Strapi → Next.js, rich content rendering) Available also in Spanish DM first so we can confirm scope and make sure it’s the right fit.
