About Me

The developer
behind the code

I'm Maksym — a Shopify developer and certified partner based in Melbourne, Australia. For the past 7 years, I've been obsessed with one thing: building online stores that actually convert.

I've worked with 80+ brands across DTC, luxury, wellness, and lifestyle verticals — from ground-up custom themes to headless Hydrogen builds. Every project starts with understanding your customer's journey and ends with measurable results.

When I'm not deep in Liquid templates or React components, you'll find me dissecting checkout flows, nerding out on Core Web Vitals, or exploring Melbourne's coffee scene.

FAQ

Common
questions

Every project is scoped individually, but most custom theme builds fall in the $10K–$25K range. Headless/Hydrogen builds typically start at $25K+. I always provide a detailed proposal with fixed pricing before any work begins — no surprise invoices.

Custom themes take 6–10 weeks from kickoff to launch. Headless builds run 10–16 weeks. Migrations are usually 3–8 weeks depending on catalog size. I provide a detailed timeline with weekly milestones so you always know where things stand.

Absolutely. While I'm based in Melbourne, Australia, most of my clients are in the US, UK, and Europe. I'm flexible with time zones and use async communication (Loom, Slack, Notion) to keep projects moving without scheduling headaches.

Every project includes 30 days of complimentary post-launch support for bug fixes and minor adjustments. For ongoing work, I offer monthly retainer plans starting at 10 hours/month. Most of my clients stay on retainer because their stores never stop evolving.

Both. I'm comfortable taking a Figma file from your designer and building it pixel-perfect, or I can handle the full design-to-development process myself. For larger projects, I collaborate with a trusted network of UI/UX designers who specialize in e-commerce.
