Why work with me

Developer, designer and store owner in one

A decade on Shopify

I've been building Shopify stores since 2016. Everything from theme development to app integrations and checkout work.

Developer and designer in one

I handle the design side myself (graphics, icons, etc.), so the whole build stays visually consistent without a separate designer.

I run a store of my own

I have my own side hustle built on Shopify, so I know how to create landing and sales pages that drive sales.

Clear, simple communication

My clients often highlight my efficiency and my open, helpful communication in their feedback.

I can only recommend Boldizsar, he did an amazing job for our marketing agency! Luckily, we were able to give him plenty of tasks, and he successfully managed to finish all of them.

Upwork review

Boldizsár has been very flexible all the time. He completed the design successfully and provided very good ideas that we didn't even think of. He went beyond what we asked for. An excellent professional!
