Milan Jankovic - Senior Shopify Developer

Shopify specialist,
not a generalist.

I work with a select number of clients at a time. Every project gets the full attention it deserves. Clear communication, fast turnaround, clean code.

I'm Milan Jankovic, a Senior Shopify Developer based in Požarevac, Serbia. With 6+ years of experience and 40+ successfully delivered Shopify projects, I help brands build and improve their storefronts. From custom development and Shopify 2.0 features to performance and overall user experience.

My work is focused on custom Liquid development. Building sections, components, and theme features from scratch that are schema-driven, interactive, and built to be maintained. Most of my work comes down to solving real problems inside Shopify stores, whether that's building new functionality, improving existing code, or making sure everything works reliably without breaking what's already there.

I specialize in Shopify 2.0 architecture: section/block systems, metafields, dynamic data, and theme performance. My focus is on performance, reliability, and pixel-perfect implementation. Writing clean, maintainable code and implementing features exactly as intended.

I enjoy building long-term relationships with clients and becoming a reliable developer they can count on for future work and ongoing improvements. I'm comfortable working independently as well as collaborating with teams, adapting to different workflows to ensure projects run smoothly.

Services

From a single custom section to a complete theme build. Every project handled with the same level of care and precision.

01

Custom Section Development

Need a section your theme doesn't support? I build fully custom Shopify 2.0 sections from scratch. Schema-driven, interactive, and compatible with any 2.0 theme. No bloated apps, no compromises.

02

Theme Customization

Modifications to existing themes that match your brand's exact requirements. I work directly in Liquid, CSS, and Vanilla JS. Maintaining theme integrity while extending its functionality.

03

Shopify 2.0 Migration

Migrating from an older theme to the full Shopify 2.0 architecture. Sections, blocks, metafields, and all modern platform features, without losing your content or customizations.

04

Performance Optimization

Improving Core Web Vitals, load times, and overall storefront performance. Faster stores rank higher and convert better. I audit, identify bottlenecks, and fix them at the code level.

05

Long-Term Development Partnership

For brands that need a reliable Shopify developer on an ongoing basis. I become a technical extension of your team. Handling new features, maintenance, debugging, and improvements as your store grows.
