You will get a production-ready FastAPI / Node.js REST API

Project details
I will build or extend a clean, production-ready backend using Python and FastAPI. This can include REST API endpoints, database models, validation, authentication integration, third-party APIs, automated tests, and Docker setup depending on the selected package.
I have 6+ years of professional software development experience and have built production systems involving FastAPI, Redis, MongoDB/PostgreSQL, cloud storage, external APIs, background processing, and complex data workflows.
My focus is not just making an endpoint work, but integrating it cleanly into your existing application. I use typed models, clear API contracts, validation, error handling, tests, and maintainable architecture.
This service works well for adding a new backend feature, extending an existing FastAPI application, building a small API module, or integrating an external service.
If your requirement is larger or doesn't fit neatly into one of the packages, message me first and we can define a custom scope.

About Nick
Senior Full-Stack Developer | Python, FastAPI, React, TypeScript
Berlin, Germany - 12:49 am local time
I help companies build new products, develop complex features, improve existing systems, and solve backend or performance problems. I’m comfortable owning work end to end — from API and database design through frontend implementation, testing, cloud deployment, and production debugging.
Some examples of my work include:
* Building a **resumable large-file upload system** for drone imagery using FastAPI, Redis, MongoDB, and cloud storage, including chunked uploads, session recovery, hashing, and duplicate detection.
* Developing an **in-house 3D web viewer** with Vue, TypeScript, Three.js, Python, and FastAPI to replace an external platform and give the product team greater control over customer-facing features.
* Building full-stack applications with **React, TypeScript, FastAPI, SQLAlchemy, PostgreSQL, and Google Cloud**, including authentication, document processing, analytics, invoicing, and API integrations.
* Working with **Docker, Kubernetes, Terraform, CI/CD, Redis, MongoDB, PostgreSQL, GCP, and cloud infrastructure** as part of production development.
I’m particularly useful when a project needs someone who can understand the product problem rather than work on one isolated layer of the stack.
I can help with:
* Python / FastAPI / Django backend development
* REST APIs and third-party integrations
* React / TypeScript full-stack development
* Existing application maintenance and modernization
* Performance and reliability improvements
* Cloud deployment and infrastructure
* AI/LLM integrations and workflow automation
I prefer practical, maintainable solutions and clear communication over unnecessary complexity.
Steps for completing your project
After purchasing the project, send requirements so Nick can start the project.
Delivery time starts when Nick receives requirements from you.
Nick works on your project following the steps below.
Revisions may occur after the delivery date.
Review requirements and confirm scope
I review your codebase, requirements, and constraints, then confirm the exact scope, assumptions, and deliverables before implementation starts.
Plan the backend implementation
I define the API structure, data flow, validation, database changes, and any required integrations so the implementation fits your existing architecture.
