Layer Four Digital Solutions
Senior Software Developer
Hi, I'm Davor
I'm a senior software developer and a builder at heart — a Flutter expert and mobile developer to the core. I turn ideas into applicable solutions and production-ready apps, owning the whole process from start to finish. I have experience in both startup and enterprise environments, where I led frontend development and mentored junior developers.
What I Do
From idea to shipped product
I design and build custom mobile and web applications end-to-end — shaping the architecture, building the solution, and seeing it through from first sketch to launch.
Mobile Applications
Cross-platform iOS and Android apps built with Flutter — with native Swift and Kotlin experience when a project calls for it.
Web Applications
Fast, modern web apps built with Next.js and React — from landing pages to full-featured products.
End-to-End Delivery
I own the whole lifecycle — architecture, backend, AI workflows, and automated CI/CD with Codemagic.
How I work
A few principles I hold myself to on every project.
Precision & craft
I get things right from the start — clean architecture and solid foundations, because rewrites are expensive.
Speed to ship
I lean on AI agents and workflows to automate the busywork and ship faster, without cutting corners.
Value & UX
I care about real value and a polished user experience — intuitive apps people actually enjoy using.
Track Record
Achievements & impact
A few numbers from the last few years — the outcomes I'm proudest of, and what it took to get there.
