I will build secure backend apis databases and integrations
Luca Wiegand
About this gig
I build and extend secure backend APIs, database workflows and external integrations for web, mobile and business applications.
Choose one primary stack per order: Java or Kotlin with Spring Boot, TypeScript with NestJS, Python, Go, or C# with .NET. I can work in a reviewed existing repository or create a scoped new service. Typical work includes REST endpoints, validation, migrations, authentication, roles, tests, Docker and third-party APIs.
Package limits count all endpoints, roles and integrations across the delivery. One database and one primary stack are used per standard order. Revisions correct the agreed behavior; new endpoints, resources, roles or workflows are additional scope.
This is a backend-only Gig: no frontend, desktop UI, machine learning or open-ended system rebuild. Source code and practical handover are included. Deployment is included only when listed or added. Please send the expected inputs, outputs, current setup and acceptance criteria before ordering Standard or Premium.

FAQ
Is this a CMS or online store service?
No. This Gig is for a custom coded public website without a CMS, shop, login system or extensive business logic.
Do you provide the text logo or legal pages?
No. You supply approved copy, branding and any privacy, imprint, cookie or other legal text.
Is deployment included?
It is included in Standard and Premium for one agreed supported target. Domain, hosting and provider fees remain your responsibility.
What does the contact form include?
Standard includes one conventional form using an agreed supported delivery method. Paid email or automation services are separate third party costs.
Does metadata guarantee SEO results?
No. I can add agreed page titles and metadata, but rankings, traffic and indexing are not guaranteed.
What does Premium defect support cover?
For 30 days after delivery, it covers reproducible defects in the delivered scope. New content, features, redesigns and third party changes are not defects.
