920four is me. zlatko. rocklin, ca.

i’ve been building products on the internet for 15 years — ecommerce, saas, client systems. it’s in my blood.

now i do two things. custom software for a few clients at a time — shopify, apps, connecting tools, the operations that don’t talk. and my own apps that anyone can use. i thrive in challenging, complex work.

you get me. no account manager. no ticket queue.
