“We hired Sasa after three other developers couldn't implement the custom functionality we needed. He built the entire page from the Figma design and solved the custom feature the same day.”
“He built a custom Shopify section directly from our Figma file and nailed it: pixel-perfect, clean code, and fully responsive.”
“Sasa is a great guy and a very experienced Replo developer. He's talented, willing to work, and very collaborative, with a quick response time. I'd highly recommend him.”
“Completed days ahead of deadline, I've only had a minor revision request. I'm planning to hire Sasa again for my upcoming project.”

Built for how people actually shop
Four years in retail at H&M taught me how customers decide. I build every product and checkout page around that.
Shopify and frontend developer with 3+ years building storefronts and landing pages for DTC brands like Vita Coco, Loop Earplugs and Luma & Leaf. I own projects end to end: UX/UI in Figma, responsive Liquid, HTML, CSS and JavaScript, app integrations and performance. I work with Claude Code every day, so builds move faster while every line is still reviewed by me.
My background is an MSc in Mechanical Engineering, so I treat a store like a system: structure first, then detail, then testing on every device.

Shopify & Webflow developer FAQ
What do you build?
I'm Saša Januzović, a Shopify and Webflow developer based in Serbia. I build Shopify landing pages, theme customizations and full stores, plus Webflow websites and Replo or Unbounce funnels for DTC brands and agencies, from Figma design to live page.
How much does a project cost?
Every project gets a fixed quote based on scope. Send a short brief and you'll have a price and a start date within 24 hours.
How long does it take?
It depends on scope. The quote includes a delivery date, and past clients have had work delivered the same day or days ahead of deadline.
Do you work with agencies?
Yes. I've built for Vita Coco, Loop Earplugs and Luma & Leaf through an agency, and work long-term with e-commerce agencies on Replo and Shopify, under your brand if you prefer.
What do you need from me to start?
A Figma file or references, collaborator access to your Shopify store (or Webflow or Replo), and your deadline. No design yet? I can design it in Figma first.
Will it slow down my store?
Performance is part of QA: every build goes through Lighthouse and Core Web Vitals checks, with lazy loading and lean code, before it goes live.
Do you use AI tools like Claude Code?
Yes. I use Claude Code, Anthropic's AI coding agent, to build and test faster: boilerplate, refactors and QA checks against the Figma design. Every line is reviewed and tested by me before it ships, and it doesn't replace design judgement or hands-on testing on real devices.
Which time zone are you in?
CET (Serbia). I've worked with clients across the US, EU and Asia. We agree on overlap hours for calls at the start, and you always get a reply within 24 hours.
Can you join our team long-term?
Yes, as ongoing part-time remote frontend capacity for your brand or agency, with hours agreed up front each month.
Have a Shopify project in mind?
Tell me what you're building. You'll get a reply within 24 hours, usually with a quote and a start date.
