  • Backend bugs: Node.js/Express errors, API failures, auth/session problems, server crashes
  • Integration issues: Firebase/MongoDB, JWT, third-party APIs, webhooks
  • Build & deployment: Vite/Webpack errors, environment variables, production build failures
  • Performance & UX: slow pages, excessive re-renders, bundle size, accessibility quick wins
  • Security & validation: input validation, basic hardening, error handling


Why choose me

  • Root-cause first: I fix the source of the issue, not just the symptom
