You will get Fix React, Next.js, or Node.js bugs in your web application
Project details
I will diagnose and fix issues in your existing React, Next.js, TypeScript or Node.js web application.
I begin by reproducing the reported behaviour and tracing it through the relevant components, application state, network requests, APIs and database interactions. I then implement a focused fix and test the affected workflow to ensure existing functionality continues to work.
I can help with React behaviour, Next.js routing and rendering, form submissions, API errors, authentication, database integration, responsive layouts and application performance.
You will receive the completed source-code changes, testing within the selected package scope and a brief explanation of the cause and solution.
I’m a New Zealand-based full-stack developer experienced with React, Next.js, Node.js, TypeScript, Supabase, PostgreSQL, MongoDB, REST APIs, Stripe, Resend and Vercel.
This project covers targeted fixes to an existing application. New features, major redesigns and architectural rebuilds require separate scoping.

About Daniel
Full-Stack Developer
Auckland, New Zealand - 3:11 pm local time
I enjoy owning projects end to end, from planning and architecture through development, integrations, testing, deployment, and ongoing support. Whether it's secure authentication, REST APIs, Stripe payments, third-party integrations, AI-powered features, or custom dashboards, I focus on building software that's reliable, maintainable, and easy for clients to grow.
My experience includes delivering a production patient assessment platform for a UK healthcare provider, shipping features for a live scheduling platform, developing WordPress and Shopify websites for New Zealand businesses, and building full-stack applications from concept through to production. I value clear communication, practical solutions, and long-term relationships with clients who want technology that genuinely supports their business.
