About

Hi, I’m Tatjana Miletic, a Shopify Developer based in Belgrade, Serbia, with 5+ years of hands-on experience in custom theme development, Liquid, and store optimization. I build production Shopify stores, implement custom features and third-party integrations, and focus on performance and UX to help businesses grow.

I enjoy collaborating with designers and project teams to deliver pixel-perfect, scalable Shopify solutions. I previously worked as a frontend developer using Vue and Angular, and I now support long-term clients through retainer-based maintenance to ensure smooth operation and ongoing improvements.
