Custom app development: tell me what it should do.
I develop web and mobile apps for customers, teams and new products. My experience includes CRM and ERP systems used in day-to-day business, with accounts, data access and integrations. We define the first version together and can agree a free basic demo of a key feature before starting paid development.
Free consultation and basic demo.
We agree what the demo will show. No obligation to hire; the full build is quoted separately.

Freelance since 2016 · Barcelona · RemoteMore about how I work
You work directly with me on design, development and testing. My professional experience is listed on LinkedIn. Some projects are covered by confidentiality agreements and cannot be shown publicly.
What kind of app do you need?
An internal tool for your team
Manage jobs, customers or bookings in one place when spreadsheets or an older application no longer support the work.
A first version of your product
Build an MVP: a first working product with the essential features, ready to test with real users.
I can help you…
- modernise an existing application
- add features to your CRM or ERP
- connect two systems that do not talk to each other
- replace a spreadsheet with an app
- build the first version of a product
- review and improve an app someone else built
How we’ll work together
What I need to get started
Tell me who will use the app and what they need to do. You don’t need to choose the technology or have every feature planned.
- 01
Describe the idea
We talk through who it is for, the main features and your priorities.
- 02
See how it could work
We can agree a free basic demo of one key feature before you commit to the full build.
- 03
Agree the build and price
I propose the features, timeline and cost. Development starts once you accept the proposal.

Questions before we start
Every project is quoted in writing after we agree the scope; there are no fixed packages. Accounts, payments and connections to other systems are the usual cost drivers. Recurring costs such as domain, hosting or maintenance are listed separately so you see them before deciding.
Do you build web apps or mobile apps?
Both. I’ll help choose based on how people will use the app, the features it needs and your budget.
What affects the cost of an app?
Features such as accounts, payments and connections to other systems affect the cost. AI agents help reduce prototype time; I quote the full app once we agree what it needs to do.
Is a demo the same as an MVP?
A demo shows part of the idea. An MVP is a working first product for real users. The agreed basic demo is free; the MVP is a separate paid project.
Can I hand the project to an in-house team later?
Yes. I deploy, document and explain the result so another developer can continue.
