Software, apps and websites built around your business

If your company runs on spreadsheets, paperwork or software that falls short, I build the tool that fits the way you actually work. You deal with me directly, from the first meeting to ongoing support.

Every tool is built around how that company works, not the other way round.

Cantera Pinos de Alhaurín

Quarry management software

A desktop application for invoices and delivery notes, per-machine costs and reports, with PDFs ready to print or email. Invoicing is VeriFactu-compliant: every invoice is registered and sent to the Spanish Tax Agency with its QR code.

Hormigones Guadarranque

Concrete plant and truck fleet

Concrete is invoiced by the cubic metre and bulk aggregate by the tonne, all in the same application. Each truck's and driver's paperwork is organised in Google Drive and opens straight from the app. With costs tracked per vehicle and per plant, they know how much profit each truck makes.

Matcon Hnos. Gámez Domínguez

Matcon QR

An operator drops a document (PDF, Word or photo) into a shared folder and, within seconds, gets a print-ready copy with a QR code that links to the document in the cloud. It runs on several computers at once, recovers on its own if the internet drops, and starts with Windows. Nobody had to learn anything new.

Own product

Klendar

A local deals and events app for Android, iPhone and the web. People discover what's happening nearby and businesses post offers from their phone. It includes a map, QR redemption, notifications, business subscriptions and an admin panel. I designed and built all of it, from the database to the app and website.

About

Iván Hijano Pérez

I'm a software engineer, graduated from the University of Málaga. Since 2022 I've been developing CaixaBank's banking app at Minsait (Indra). That's where my way of working comes from: test everything thoroughly, care about the details and deliver things that work.

Alongside that, I build custom software for businesses. I like to visit on site, see how people work and build tools they can use without a manual.
