Filip Rastovic - Senior Shopify Developer

Always questioning the world around me, I enjoy reading fat books, playing guitar, listening to music, and working out. Used to live in the World of Warcraft as a teenager, defeating the Lich King with the guild <Digital Crew> that I led. I hold a bachelors degree in Software Engineering and have been working with global brands for the past nine years.

Mentions in Media (Mostly Serbian)

I used to do 3D art a bit, it got kind of viral. (Offers from Google & Microsoft)

Cool Pictures

About The Images

I rendered these images in Cinema 4D using Octane Render from 2020-2023. I was really obsessed with 3d art back then. I’m very proud that both Google and Microsoft reached out to do 3D work for them. However I don’t do much 3D these days.

The 3D models in images above are mostly downloaded high quality assets, put in a procedurally generated background setting.

The lighting & compositions, my favourite topics, are very traditional in every image. I’m trying to highlight form of the objects, lighting one half and leaving the other one in shadow.

You can download my stuff for free! If you print it, shoot me a message, I want to see how it looks on your wall! There’s much more on the blog below.
