Niko Miljanić

I build AI-enabled web applications, API integrations, and workflow automations through LJEMICUS DIGITAL, taking work from discovery and implementation through testing, deployment, and handover.

My delivery process uses explicit acceptance criteria, validation, security checks, production builds, and reproducible evidence. I build with TypeScript, React, Next.js, Supabase/PostgreSQL, server-side APIs, and responsive interfaces.

My projects include Šapica / PetPark, a Croatian pet-services marketplace with authentication, realtime messaging, booking flows, and automated quality checks, and Midnight Consent Demo, which demonstrates privacy boundaries, typed interfaces, automated tests, and reproducible documentation.

I also bring 13 years of client-facing dental-clinic operations and management experience, including team leadership, service quality, multilingual communication, marketing coordination, and practical business operations.
