I will build a secure rest API backend for your web or mobile app
Joao P.
About this gig
Your web or mobile app needs more than endpoints: it needs a backend that protects data, enforces business rules, and gives the client a clear contract.
I will build a scoped REST API with models, validation, documented endpoints, structured errors and, when included, authentication, roles, permissions, filters, pagination, tests, Docker, and deployment.
Packages are measured by resources, endpoints, roles, and workflows, not vague "complete app" promises.
Technology and stack selection: I follow an existing architecture only when it uses my supported technologies. For new backends, I deliver with Python, Django/DRF, and PostgreSQL or suitable SQLite. I recommend the configuration from the rules, maintenance, hosting, integrations, expected usage, and delivery risk. I do not claim unsupported frameworks.
Frontend, payments, chat, real-time features, workers, provider approvals, data migration, and enterprise infrastructure are separate scope.
Send your users, roles, entities, rules, integrations, and acceptance criteria before ordering.

FAQ
Which technology will you use?
For backend implementation I currently support Python, Django, Django REST Framework, PostgreSQL, and SQLite where appropriate. I select the configuration according to the project's rules, deployment, maintenance, integration, and usage needs.
Can I choose the technology?
Yes, when your required technology is inside the supported stack. If your existing application mandates Node, Laravel, FastAPI, Flask, or another unsupported backend framework, this gig is not currently the right fit.
What if I do not know which technology I need?
Provide the product requirements, expected users, hosting constraints, frontend/mobile context, integrations, and maintenance expectations. I will recommend a suitable option within the supported stack and explain the trade-off briefly.
What is a resource, endpoint, role, and workflow?
A resource is a business entity; an endpoint is one route/method operation; a role is one permission profile; and a workflow is one bounded multi-step rule sequence. These units determine package fit.
Is the frontend included?
No. This gig delivers the REST API backend and its documentation. A React/Next.js implementation or small integration example requires separate scope.
Is deployment included?
One Render deployment is included only in Premium. Domain, paid hosting, DNS, email, storage, and third-party fees remain the buyer's responsibility. Other environments require review.
Do you guarantee complete security or unlimited scalability?
No responsible developer can. I apply appropriate authentication, permissions, validation, secret handling, database constraints, transactions, and tests for the agreed scope. Formal audits, compliance, load testing, and distributed architecture are separate services.
