AI-native Senior Software EngineerZagreb, Croatia

Hi, I'm Davor

I'm an AI-native senior software engineer and a mobile fanatic: Flutter to the core, with Next.js, cloud backends, and the DevOps around them. I build with AI agents every day and ship LLM features into production, owning the whole process from architecture to release. I've led frontend teams and startup development, including a planning app that won a €2M public tender. I build and ship my own mobile apps on the side, and I'm currently at NEOGOV, building HR software for the US public sector with agentic development and AWS.

01/What I Do

From idea to shipped product

I design and build custom mobile and web applications end-to-end, AI-first: shaping the architecture, building the solution with AI agents at my side, and seeing it through from first sketch to launch.

01
Mobile Applications
Cross-platform iOS and Android apps built with Flutter, with native Swift and Kotlin experience when a project calls for it.
02
Web Applications
Fast, modern web apps built with Next.js and React, from landing pages to full-featured products.
03
AI & Agentic Workflows
LLM features in production with evals and observability, and agentic workflows that help whole teams ship faster.
04
End-to-End Delivery
I own the whole lifecycle: architecture, backend, containers and Kubernetes, and automated CI/CD with GitHub Actions, Codemagic, and fastlane.

02/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.

03/Track Record
