You will get a production-ready MVP built from your concept or spec
Project details
You have an idea or a spec. I'll turn it into a working product - deployed, tested, and ready for real users. Not a demo that falls apart when someone actually uses it. A real first version you can run a business on.
I work in React, Next.js, Node.js, TypeScript, and Python/FastAPI. PostgreSQL for the database. Docker for deployment. CI/CD so every push gets tested automatically. You get monitoring, logging, and proper error handling from day one.
13 years shipping production software. I built and shipped my own product (Liberoscan) solo, spent 8 years on a B2B SaaS platform with 200k+ users (orgavision), and before that 4 years of full-stack work at EasyBib and Chegg serving millions of users on AWS.
How it works: we get on a call, I scope the work, and I give you a fixed price with milestones. You pay per milestone through Upwork escrow. I deliver working software at each step, not progress reports.

I cover the full stack. Frontend, backend, APIs, database, deployment, CI/CD. I can deliver a project solo from start to finish or plug into your existing team. I'm used to code reviews, sprint planning, and working across time zones. Either way, you get someone who owns their work end to end.
I've built custom prediction models with PyTorch and run distributed training on Ray clusters. My own product, Liberoscan, processes financial statements with LLMs and returns every figure with a source citation. If your project needs AI, I know where the real engineering problems are.
Python is my second stack. FastAPI, Flask, data pipelines, ML infrastructure. When a project needs heavy backend logic or data processing, that's what I reach for.
Everything I build ships with tests and automated deployments. Unit tests, integration tests, CI/CD pipelines that run on every push. Before I ship, I make sure it works as designed.
I start lean but I don't cut corners. Everything ships with monitoring, logging, and proper error handling. Docker, reproducible builds, deployed wherever it needs to run on AWS, Hetzner, Fly, or Azure. You get something you can actually run a business on, not a demo. I'll tell you when something doesn't make sense or when you're overengineering.
Based in Germany, CET.
Steps for completing your project
After purchasing the project, send requirements so Sascha can start the project.
Delivery time starts when Sascha receives requirements from you.
Sascha works on your project following the steps below.
Revisions may occur after the delivery date.
Scoping call and architecture
We get on a call, I scope the work, define the data model, tech stack, and milestones.
Build and iterate
I build in iterations, shipping working software at each milestone. You see progress throughout.
