Fast websites that turn visitors into clients

I build Angular and .NET business applications, plus Astro + Strapi sites that hold 98+ on Lighthouse. The Three.js museum work that lifted visitor engagement 45% is mine too.

About me

Full-stack developer in Sarajevo. I started on agency platforms and now build products of my own.

Full-stack developer with 5 years of commercial experience shipping production Angular, TypeScript and .NET applications. My work runs from enterprise management systems to interactive museum installations, built on clean Angular architecture and a practical design-system habit, with AI tooling folded into daily delivery.

These days most of my client work runs on StrAst, my own Strapi + Astro setup for building fast, reliable websites; this site is one of them. Before that I spent three years leading frontend development at RootId in Sarajevo. On the side I run QUIZZIQ, a live quiz tournament platform I built alone.

Outside work I play futsal at a semi-professional level and take chess more seriously than I probably should.

What I do

Five ways we can work together.

Frontend Development

Web applications in Angular, Svelte, Astro and TypeScript, implemented to the pixel from your designs. Performance is a requirement here, and the Lighthouse scores on this site show the standard.

Full-Stack Solutions

Complete applications with a .NET backend, REST APIs and database design behind a modern frontend. One person covers the whole stack, so nothing gets lost between teams.

Interactive Experiences

Three.js 3D environments, GSAP animation and gesture recognition. The museum installation built this way lifted visitor engagement by 45%.

CMS & Headless Architecture

Strapi headless CMS setup, content modeling, GraphQL APIs and fast static frontends with Astro. Your editors publish without waiting on a developer. Built on my StrAst framework: Astro, Svelte and Strapi.

Consulting

One session or a full roadmap. I advise on SaaS products, web applications, websites, SEO optimization and social media strategy. You leave with a concrete plan and a straight answer on what to build first.

Why Astro + Strapi Is My Default Stack for Content-Driven Sites

I've shipped a dozen marketing sites on this stack, plus two product launches and the portfolio you're reading. Here's why I keep coming back to Astro and Strapi, and where I wouldn't reach for them.
