I will build a production ready python fastapi backend API
Arijit K
About this gig
I will build a scoped Python FastAPI backend API for your product, internal tool or AI application, based on agreed user flows and acceptance criteria.
Basic: one bounded module with up to 5 endpoints, request validation, OpenAPI documentation, source code, README and basic tests.
Standard: up to 12 endpoints, PostgreSQL schema/migrations, JWT authentication with defined roles, one background job OR third-party API integration, Docker, tests and handover.
Premium: up to 20 endpoints, PostgreSQL, authentication/roles, Redis or background tasks, up to 2 integrations, Docker, structured logging, CI-ready tests, buyer-environment deployment configuration and operations documentation.
No frontend/mobile app, UI design, cloud bills, broad unknown-codebase refactor, security certification, payment compliance, unlimited endpoints or ongoing operations.
Message before ordering with your user flows, data model, authentication roles, integrations, existing stack and definition of done. Larger products need separate milestones or a custom offer.

FAQ
Can you build an entire SaaS or work in an existing repository?
This Gig covers a defined backend module or foundation. A full SaaS needs separate scoping and milestones. I can work in an existing repository after a brief review when access is authorized and the requested change is bounded.
Do I get source code, and will you deploy the API?
Every package includes the agreed source code and setup documentation. Premium includes deployment configuration for your environment. Live deployment, hosting charges and ongoing operations are separate unless explicitly scoped. Do not send passwords or production secrets in chat.
