I will build a production rest API or backend integration
Zach Esenbock
Informazioni su questo servizio
I build REST APIs and backend integrations that move the right data between business systems and make failures visible. My experience includes healthcare-adjacent operations, vendor workflows, validation, and auditability.
Before coding, we define the source and destination, fields, trigger, expected result, and retry or exception behavior. This turns a vague integration request into a testable workflow.
Endpoint: one contained endpoint or integration workflow.
Service: an agreed multi-endpoint service or substantial integration, data modeling, error handling, and deployment guidance.
Subsystem: a defined backend subsystem with broader tests, deployment support, and recorded handoff.
Delivery includes validation, automated tests, documentation, and updates at least every two business days during active work. We agree scope changes before building. Maintenance or periodic reliability reviews can follow under a separate scope and response window.
Frontend apps, hosting, licenses, provider fees, broad migrations, data cleanup, and unrelated workflows are excluded. Revisions refine agreed behavior.

I help businesses diagnose slow APIs and SQL, repair unreliable integrations, and improve production reliability. In one tested API workload, I helped increase throughput from about 1.15 to 51 requests/second and reduce median latency from 21.5 seconds to 450 ms. Results apply to that workload.
Start with one application or workflow: a baseline, ranked findings, and a fix plan. Implementation follows an agreed scope with tests, progress updates, and handoff notes. Architecture and AI integration support the business outcome.

FAQ
Which stacks can you use?
I commonly work with TypeScript, Node.js, NestJS, REST APIs, PostgreSQL, SQL Server, Prisma, C#, .NET, and cloud infrastructure. The existing system and buyer constraints determine the final choice.
Is deployment included?
Guidance is included in Standard and deployment support is included in Premium. Hosting and third-party costs are not included, and production changes require buyer authorization.
Are automated tests included?
Yes, focused tests are included in every implementation package. Test depth follows the agreed business rules and integration boundaries.
Can you integrate a third-party vendor?
Yes, when the buyer supplies accurate documentation, authorized sandbox access, and a responsive vendor contact if needed. Vendor delays may affect delivery.
