What I'm looking for

I'm looking to build scalable, high-performance web applications where I can apply React, Next.js, TypeScript, headless CMS architecture, serverless workflows, and performance optimization.

I've delivered production web applications for Viktori Travel, IT Dojo, Montaža Tehnik NP, Fasada Festival, and PD Slobodna Zona as a freelance developer since 2022.

For Viktori Travel, I built a TypeScript and TanStack Query data layer that lets non-technical staff update data through Excel, plus a weighted matching algorithm for 30+ US internship programs that reduced manual screening by 60%. I also implemented serverless honeypot protection that eliminated 99% of bot spam and wrote Vitest coverage for the program-fit calculator.

At IT Dojo, I created a zero-maintenance curriculum engine that synchronizes YouTube playlists with the course platform in real time and reduced API quota usage by 90% with caching strategies.

My work centers on React, Next.js, Astro, TypeScript, headless CMS architecture, Core Web Vitals, and serverless solutions. I bring a systems-oriented foundation from studying C++, applying it to reliable backend logic and high-performance interfaces.
