Software Development and Coding in Spain

At some point, off-the-shelf packages aren't enough. Your bookings follow a rule unique to your business, your customers log in with a membership, payments are collected differently in Spain and in Türkiye, and your team fills in the same spreadsheet by hand every morning. At that point, what you need is software built around your business.

I also build my own products, so I think of the work not as lines of code but as a product running live. Some examples: dinle.link, a link-in-bio platform for musicians; Ketsy, a management platform for educational institutions; RADIOS, a sales and broadcasting platform for radio stations; and the music distribution platform Digitalent Music. All of them are live and used by real users.

We define the scope together, and I build it end to end, from database to interface, from hosting to security and backups. The software is designed to work in any language; Turkish, Spanish and English interfaces are managed from the same system.

Details of my general software service are on the software and platform development page.

Common Questions

Off-the-shelf or custom software?

If your business runs comfortably on off-the-shelf software, you don't need custom software, and I'll tell you so plainly. Custom software makes sense where ready-made tools hold you back or where you're manually stitching several tools together.

Do you build mobile apps?

I build mobile-friendly web applications that work like an app on your phone. Whether you need a native app from the app stores is something we decide together based on your needs.

Who owns the code and the data?

The data is yours. Ownership of the code and usage rights are clearly stated in the proposal.

Can we add features later?

Yes. The system is built to grow, and new features are planned based on usage data.

Which brands and artists have you worked with?

I've run the digital strategy, music distribution and official websites for Murat Boz, Ebru Gündeş and Emre Altuğ. On the brand side, I've worked on the Ford Otosan × İlhan Şeşen AI-powered campaign (MIXX Awards 2017) and with Mercedes-Benz, Koton, Avşar Film, Medyapım, Model Sanayi Merkezi, Alpet, Kadoil, Kadooğlu Holding and Damat Tween.
