Which tools do you use?
I choose the platform per project, based on your goals and how technical you are. The Build Plan includes this tool selection and explains the choice.
Who owns the app and the data?
You do. Your data, apps and tool accounts belong to you, with no lock in.
Do I need my own accounts?
Yes. We choose the platform together based on your requirements, long-term plans, technical comfort, and budget. I then build directly in your accounts as an invited guest, so you pay tool subscriptions directly and maintain 100% ownership.
How much do you charge?
€125 / hour (plus VAT where applicable). Outside Europe, I provide a custom quote.
Can I get a fixed price for the whole project?
No. I bill by the hour, so you stay in complete control of your budget. Work is split into features, scoped before we start, and each one is paid upfront.
Do you work with clients outside Europe?
Yes. I work with clients worldwide, primarily across Europe and North America. Projects are billed at my standard €125/hour rate, and I provide a tailored quote to account for your local VAT or international tax rules.
How long does a feature take?
Typically 2 to 5 hours of work each.
How do I pay?
Each feature is paid upfront and in full, by SEPA bank transfer. Card payment is possible on request. Invoices are due on receipt, before work starts.
What does the Build Plan cost?
It takes about 2 to 5 hours of work at the hourly rate, plus VAT where applicable, and is ready in 5 working days from receipt of payment and your written brief. You get one document with 6 deliverables: problem summary, feasibility and tool selection, prioritized feature list, effort estimate as a range of hours, risks and recommendation, and a statement of work. For consumers, prices include VAT.
How fast can a prototype or MVP be ready?
Typically a few weeks. We build only what is necessary to test the concept with real users or investors: core workflows, clean design, and real data, so you can validate adoption before committing to heavy engineering.
Is a revision round included in the Build Plan?
The clarification happens before the plan is written: after a first call or written exchange, we go back and forth two or three times until nothing is left open. You then receive one finished document, with no separate revision round. You can use it however you like: shelve the project, change direction, build it yourself, or have me or another consultant build it.
What happens after delivery?
You test and review each feature. Features count as approved after 7 days without feedback. Corrections and amendments are billed.
Do you use AI?
Yes, at every step: planning, building and troubleshooting. I review the results. I almost never enter client data into AI tools, and only anonymised information.
Can you teach me instead of building?
Yes. Teaching sessions work on your own project. They take longer than building, at the same hourly rate.
Can I stop after a feature?
Yes. Work already done is not refunded, and unused prepaid hours are refunded.
Which languages do you work in?
English, French and German.
