Custom application development
→ UX is the keystone.
Save time by automating your repetitive tasks.
The service
When off-the-shelf software doesn't fit your trade, you either adapt your trade to the software, or the other way around. Custom applications do the latter: they match your actual work flow. You keep control: everything is configurable, documented, and stays your property.
For whom?
SMBs and independents with a specific business process not well covered by existing tools. Typical cases: workflow automation, internal management app, B2B tool, member or customer portal.

How much does a custom application cost?
A custom business app typically starts at €8,000 for a simple MVP delivered in a few weeks, and can go up to €50,000+ for a complete solution with complex workflows, role management and integrations. I always offer a free initial scoping session to estimate precisely before any commitment.How do I know if I really need a custom app?
If you're adapting your way of working to fit off-the-shelf software, if you're accumulating spreadsheets and plugins, or if your clients are asking for things your current tool can't do. It's usually the right moment. A free 30-minute audit helps decide objectively between custom, existing SaaS, or a combination.How long does it take to deliver an app?
An MVP usable internally ships in 6 to 10 weeks. A complete application with polished UI, role management and integrations: 3 to 6 months depending on complexity. You see progress every week through regular demos, and you reorder priorities as we go.Will I own my data and source code?
Yes. The source code belongs entirely to you, data is stored on infrastructure of your choice (your cloud, or hosting I manage), and everything is documented so any competent developer can take over. No proprietary service lock-in, no hidden license fees.What if my needs evolve after delivery?
The application is built to evolve. Technical documentation lets any competent developer take over. I can continue maintenance and evolutions, or work with you occasionally when a new need comes up. You're never locked in.
