Hire a Freelance Backend Developer for a Fixed-Scope Project
One thing to build. A defined price. A clean handover. No ongoing commitment, no scope ambiguity — just a backend built and delivered.
How project-based work works
You describe the problem. I read it, ask any clarifying questions, and come back with a written scope: what gets built, what's explicitly excluded, the delivery timeline, and a flat price. You review it, we align on anything that's unclear, and then I build it.
The price doesn't change after the scope is agreed. If the requirements change, that's a separate conversation with its own price — not an open tab that grows quietly in the background. The scope is the contract.
What projects work well
Project-based work is the right fit when you can describe what done looks like. The most common types:
- Stripe billing and subscription flows — subscription setup, payment intents, webhooks, billing portal, dunning logic
- Webhook systems and event pipelines — ingestion, deduplication, delivery, retry logic, receipt verification
- API integrations — connecting your product to a third-party service via REST or webhook
- Single-purpose SaaS tools — calculators, reporting tools, admin utilities, single-file or full-stack
- Content automation pipelines — WordPress or Ghost publishing via REST API, programmatic scheduling
- VPS infrastructure setup — nginx, Docker Compose, SSL, self-hosted deployment from scratch
What you receive at handover
At the end of the project you get everything needed to operate and maintain the work independently:
- Full source code, structured and readable
- A working deployment if that was in scope
- Enough documentation that a developer unfamiliar with the project can maintain it
- A brief summary of what was built and any decisions that were made during the build
There is no lock-in. The code is yours. You are not dependent on me to keep the product running.
What a good brief looks like
A brief doesn't need to be a specification document. It needs to answer three questions: What problem are you solving? What does a working solution look like? What are the constraints — timeline, existing stack, integrations required?
The more specific the brief, the faster the scope turnaround and the more accurate the quote. If the problem is still being defined, that's a signal to start with an hourly consultation rather than a project.
Frequently asked questions
How is the project price determined?
Based on the scope — what needs to be built, estimated complexity, and delivery timeline. After you send a brief I outline what gets built and quote a flat rate. That rate doesn't change unless the scope does.
What's the minimum project size?
From €1,500 for small tools and integrations. SaaS features and backend systems typically start from €3,000. The minimum reflects a realistic scope — anything smaller is better handled as hourly work.
What if the scope changes mid-project?
Scope changes are handled explicitly. New requirements after the scope is agreed are treated as a separate item with their own price. The original quote covers the original scope — no silent expansion.
How long does a project take?
Small tools and integrations: one to two weeks. SaaS features and backend systems: two to four weeks. Larger builds are quoted with a specific timeline. The timeline is part of the agreed scope, not an estimate that drifts.
Do you require a deposit?
Yes. Typically 40–50% upfront before work begins, with the remainder on delivery. For smaller projects the full amount may be invoiced upfront.
