I will fix or add a nodejs or nestjs API endpoint


About this gig
Make your web app work with the data and services it needs.
I build and repair Node.js/NestJS APIs in existing projects, with clear scope and practical handover notes.
I can help with
- Broken endpoints and validation errors
- Small database-backed API features
- External-service integrations and webhooks
- Frontend/backend data connections
Every package includes
- The agreed source changes
- Relevant input validation and error handling
- Checks of the affected flow
- Clear endpoint usage notes
- 30 days of support for defects in my delivered changes
Choose one simple endpoint, one small feature with up to 3 related endpoints, or one external-service integration with up to 5 related endpoints.
I have 7+ years in web development, including business platforms, APIs and CRM workflows.
Please message me with your goal, current stack and API documentation before ordering. A runnable project and safe test access are required. New backends, complex workflows, deployment and provider fees need separate scope.
Tell me what needs to connect - or what isn't working.

FAQ
What do you need before I order?
Message me with your goal, stack, API documentation and reproduction steps. An existing runnable Node.js/NestJS project and safe test access are required. We agree endpoints, rules and dependencies before ordering.
Can you build a new backend from scratch?
Yes, with a separate scope review and custom quote. Introductory packages extend or repair an existing runnable project; they do not include an entire new backend.
What is included in the packages?
Basic: one simple endpoint. Standard: one small feature, up to 3 related endpoints. Premium: one external-service integration, up to 5 endpoints. We assess complexity before ordering. Source changes, relevant validation/checks and usage notes are included.
What does 30-day bug support cover?
Defects in my delivered changes for 30 days from the handover/delivery date agreed with you. New requests, unrelated bugs, third-party failures and later external changes need separate assessment. Defect corrections do not consume revisions.
Are hosting, deployment and service fees included?
Provider subscriptions, infrastructure and usage fees are separate. Deployment to one existing supported buyer-owned environment is a $20 extra. An additional simple endpoint is $20. Each adds one day; suitability is checked before ordering.
What counts as a revision?
One collected feedback list refining the agreed work. Basic includes 1 round, Standard 2 and Premium 3. Additional endpoints, features or changed business rules need separate scope.
