Get API integration and backend development from a top-rated U.S. SaaS engineer backed by $350K+ earned, 219 completed transactions, and 100% performance on Guru.
I design, build, and connect backend systems that move data reliably between applications, services, and third-party platforms. I can develop a new backend component or repair and extend an existing integration that has become unreliable.
Typical work includes REST or GraphQL APIs, webhooks, third-party API integrations, authentication, data synchronization, database functionality, background jobs, payment and messaging integrations, error handling, logging, and server-side performance improvements.
You receive a maintainable implementation with practical documentation and clear communication about dependencies, edge cases, and failure handling. This service is a strong fit when you need systems connected, backend functionality expanded, or a brittle integration stabilized for production use.
