You will get a production-ready Python FastAPI backend

Project details
You're not buying a tutorial-grade FastAPI app. You're getting a backend
designed to actually run in production — the same stack I've used to ship
HIPAA-compliant healthcare platforms, identity infrastructure for B2B
SaaS, and LLM-powered APIs serving real traffic.
What that means in practice: clean architecture with dependency injection,
async database integration (PostgreSQL or MongoDB), OAuth2/JWT auth done
right, Docker setup that works locally and in production, Pytest coverage,
and deployment to AWS or GCP. Auto-generated Swagger docs so your team
(or future developers) can pick it up without asking.
Most catalogs sell you a prototype dressed as a product. I sell the
opposite: maintainable code your future self won't regret. Three tiers,
clear scope, fixed price. Pick the one that matches your stage — MVP,
growth, or enterprise — and we ship.

Senior Fullstack Engineer for PWA Rebuild on AWS
Christian worked with us for a few months on the AWS architecture and backend for a new web app. He was helpful and took pride in his work and we appreciate his support through the process.

Its impossible to rate Christian on his work as he wont release it to us. Though I wish him well, and he had some personal issues that complicated our project

Desktop Application Developer for Automated Lyric Slides
It was very satisfying to work with Christian. I had a time restriction and needed someone who knew his stuff and Christian was provided just that. Besides being able to act as a product manager with a broad knowledge of the business and the costumer needs, his seniority as a developer was shown in the more nitty gritty technical aspects of the solution I wanted to develop. I felt constantly reassured that I hired the right person for the job and would no doubt work with him again.

What sets me apart: behind my backend specialization, speed, quality, and cost stay balanced because you see every trade-off and make the call with me.
I don't just wire up an API. I architect the data flow, own the cloud infrastructure, and handle complex auth (OAuth2, OIDC, SAML),so you don't need to manage different contractors.
With Top Rated Plus status and $150K+ earned across 7 active contracts, my clients keep coming back for two simple reasons: I communicate clearly, and I ship on time.
🐍 Python backends — FastAPI, Flask, Django, async workers, parallelism
⚡ Node.js / TypeScript APIs — Express.js, Nest.js, REST, GraphQL, Supabase integrations
🐹 Golang services — high-performance APIs, concurrency, microservices
🤖 AI & RAG pipelines — LLM orchestration, vector search, embedding workflows
📊 ETL & data engineering — GCP BigQuery, PostgreSQL, MongoDB, Kafka, RabbitMQ, SQS

Send me a message with what you're trying to build or fix — a single sentence is enough to start. I'll tell you how I'd approach it and the trade-offs to expect, so you can evaluate the fit before we scope anything. Detailed spec or just a rough idea, send it over.
Steps for completing your project
After purchasing the project, send requirements so Christian can start the project.
Delivery time starts when Christian receives requirements from you.
Christian works on your project following the steps below.
Revisions may occur after the delivery date.
Kickoff: align scope, requirements, and deliverables
We confirm the project scope, data models, and endpoints to build. Tech choices (DB, deployment, auth) get locked. Standard and Premium tiers include a live kickoff call; Basic uses structured async messaging via Upwork.
Architecture design and FastAPI project setup
I design the API structure — routes, schemas, database models, auth layer — and set up the FastAPI project with clean folder structure, dependency injection, Docker, and environment configs. Foundation built right from day one.
