Freelancer profile translated to English.

Description

I build custom desktop, web, and Android applications for businesses that need to go digital without relying on the cloud or monthly fees. My clients are companies with specific operations — hospitality, access control, industrial management — that need software that works in their environment, not in an external provider's.

At Golfmanager SL, I developed certified integrations with SiteMinder, OHIP Oracle, Comercia Global Payments PCI-DSS, and CashLogy, as well as access control modules for Real Club de Golf de Sevilla and Hulencourt (Belgium). These were projects with demanding technical requirements, realistic deadlines, and institutional clients.

To deliver this level of quality at competitive prices, I developed Bowner: my own infrastructure that covers 90% of any application's technical needs before writing the first line of business code. I also work intensively with AI under strict architectural supervision — which allows for speed without hidden technical debt. I deliver in weeks what others take months for.

I work on Bowner and in Windows and Android environments. If your project requires a different stack or macOS/iOS, I'm not the right choice — and I prefer to tell you that upfront.
