troubleshoot and fix API, webhook and backend integration issues

About this gig

Is your API, webhook, or backend integration failing, returning errors, or behaving unexpectedly?

I can investigate and troubleshoot integration problems and implement a clean fix.

I can help with:

API request and response errors

Broken webhook processing

Authentication and authorization issues

Invalid JSON/payload handling

Third-party API integration problems

Database and persistence issues

Duplicate webhook/event handling

Backend debugging and error handling

Node.js, Next.js and TypeScript issues

My approach is to understand the failure, identify the root cause, implement the appropriate fix, and verify the affected workflow.

Technologies include TypeScript, JavaScript, Node.js, Next.js, REST APIs, PostgreSQL, Prisma and Supabase.

Please contact me before ordering with the error, expected behavior and relevant documentation so I can confirm the scope.

I build reliable backend integrations that connect e-commerce platforms, APIs, databases, and business workflows. I can help with REST API integrations, webhooks, PostgreSQL/database workflows, e-commerce automation, third-party service integrations, debugging, and integration troubleshooting. My focus is practical: secure data flow, validation, idempotency, error handling, and maintainable code rather than unnecessary complexity. I work primarily with TypeScript, Node.js/Next.js, PostgreSQL, Prisma, Supabase, and REST APIs.
