Davor Komusanac
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
