Create clear API endpoints that let your frontend or another service read and update data. I work with Express and FastAPI, using documented requests, responses and validation.

Starting at $100: up to two related endpoints for one resource in an existing runnable backend and database. Includes request validation, consistent error responses, example requests and focused checks. One revision within scope. Typical turnaround: 5 business days.

Suitable for adding a small feature to an existing app. A new backend from scratch, authentication systems, payments, complex permissions and large database changes are quoted separately. I will agree endpoint behavior and acceptance examples before implementation.

Proof: CompanyMind includes Express routes and services connecting a React frontend to MongoDB and a FastAPI service. https://github.com/nikhilkumarpanigrahi/Companymind
