i build software for businesses — client work, and products i ship myself.
15 years of building products on the internet. it’s in my blood.
zlatko · just me.
client work
something in the business is stuck. a workaround became someone’s job. when it breaks, nobody knows who to call.
that’s what i build. shopify, custom apps, connecting the tools you already pay for. i thrive in challenging, complex work.
shopify · custom apps · api integrations · workflows · operations · wholesale · qbo · crm · webhooks · ios + android
the shop
problem in
orders live in a spreadsheet
becomes
product out
a wholesale portal
sometimes that’s a tool only your team will see. sometimes it becomes an app anyone can use. either way, i built it.
client work
work i built for clients.
my own apps
apps anyone can use.
products i shipped myself — not custom client work. name, what it does, the live site. if you need one of these wired into how your business actually runs, that’s a client project.
