Common Questions & Concerns
Still have questions? Let's clear a few things up.
What if this ends up like the last freelancer we hired — late and vague?
I run every sprint like a product team: clear scope, a mid-sprint check-in, and clean delivery. You always know what's being done — and when.
How do I know the quality is any good?
I’ve shipped production code for BMW, TUI, ING, and multiple startups. I write tested, maintainable code your team can build on — not throwaway work.
What if we don’t have specs or clear requirements yet?
No problem — we start with a free 2-hour planning session. I help you shape your goals into scoped, point-based stories. You only commit once we’re aligned.
Can you work with our stack or existing codebase?
Yes. I’ve joined mid-projects, inherited legacy code, and plugged into new stacks. I ramp up quickly and work async-friendly — no micromanaging required.
What’s the risk if this doesn’t work out?
There are no long-term contracts. You pay 50% upfront, 50% on delivery. If you’re not happy after a sprint, you don’t book another. Simple.
