I work with Microsoft technology and build it to fit you, not by forcing a template. ## What your web application includes Software built to fit you, connected to your systems and made to grow with you. **Built around your process** The application adapts to how your company works, not the other way round. **Scalable and maintainable** Designed to grow without becoming fragile, and checked by automated tests that flag a problem before your team ever notices it. **It gets on with what you already have** It connects to your current tools (Microsoft 365, your management software, your payment provider) so nobody has to type the same data twice. **Everyone sees only what they should** Permissions per person, sensitive data encrypted, and a record of who logged in and what they looked at. I apply the same standard to portals holding medical data, where there is no room for error. **Launch included** I take care of the server, the security certificate and the backups. With a written rollback plan before touching anything, so an update never leaves you without service. ## When is a custom application worth it? It usually pays off when one of these happens: - You type the same data into two or three different programs every day. - A spreadsheet has become the company system and nobody dares to touch it. - Several people (customers, staff, suppliers) need to see different information about the same process. - The standard software you use forces you to work its way instead of yours. And when it is not worth it: if a standard program already does almost everything you need, adapting to it is usually cheaper. I tell you so in the first conversation. ## Examples of what can be built These are types of project, to give you an idea of the scope: | Need | What gets built | | Let your customers check their own information | A portal with a login per user, where each person sees only their own data | | Run the operation from one place | An internal dashboard with the day's data, alerts and tasks | | Appointments, bookings or orders with your own rules | A booking or ordering system shaped to the way you work | | Stop copying data by hand | A link between your programs (Microsoft 365, your ERP, your payment gateway) | | Reports you put together by hand today | Reports that build themselves from real data | ## Real work: a portal with three profiles For Centro Moreau I built a patient portal with three profiles: patient, doctor and insurer. Each one sees only what concerns them. With health data there is no room for error, so permissions and the access log are designed from day one, not at the end. ## How a project in phases works This way you never pay up front for something you have not yet seen working: - Analysis: I understand the current process, who uses it and what fails. - A proposal and a closed quote by phases, with the essentials first. - A first version with the essentials, to use as soon as possible with real data. - Go-live: server, certificate, backups and a plan to roll back if something fails. - Improvements in later phases, based on what real use has shown. ## Why custom software, and when you do not need it **I understand the problem before the code** I start from your business need, not from whichever technology is fashionable. **I work with Microsoft technology** The same technology your office already runs on. That avoids reinventing what your company has already paid for. ## Frequently asked ### What is the difference between a website and a web application? A website informs (it presents your business); a web application does things: it manages data, automates processes, has users and logic. If you need to operate, not just display, it is an application. ### Does it integrate with my current systems? Yes. I design the application to connect with what you already use (Microsoft 365, your ERP or CRM, external services or your database). ### How much does it cost and how long does it take? It depends on scope and complexity. After analysing your case I send a closed quote and a schedule with phased deliveries. ### Who takes care of the server? I do, if you want. I run the servers where my clients' projects live, with their backups and certificates kept current. That is the difference between handing over an application and handing over something that still works two years from now. ## Related services [Custom web design](https://romadev.studio/en/web-design-mallorca/) [Analytics service](https://romadev.studio/en/web-analytics-reporting/) [SEO service](https://romadev.studio/en/seo-mallorca/) ## Shall we look at your actual case?
