About this gig

Need to connect a third-party service to your app or automate data exchange between existing systems?


I build custom REST API integrations and webhook workflows with Node.js, TypeScript, Go and PHP. My approach is API-first: clear data mapping, maintainable code and appropriate error handling instead of unnecessary dependencies.


I can help with REST APIs, webhook receivers, JSON/XML parsing, authentication integration, synchronization workflows, event processing and troubleshooting failed API calls.

You will receive working source code, focused verification and setup notes for the agreed package.


Please contact me with your API documentation, expected input/output and application stack before ordering. OAuth approvals, multiple external platforms, production deployment and undocumented integrations may need a custom quote.

Backend engineer with 8+ years of experience building backend systems, API integrations, and automation for business and financial workflows. I specialize in undocumented APIs and mobile/web app flows, then turning that into clean, secure middleware and automation. I work async-first with written documentation and clear updates, and I deliver a working trial or MVP within 4–8 hours of receiving clear requirements, so you can validate the approach before committing to a full build.
