Engineering custom commerce infrastructure for established Shopify merchants.
I help stores past $10k/month get through the technical ceilings that themes and apps can't solve — with Shopify Functions, bespoke theme logic, and integrations built to last.

I partner with merchants who've outgrown generic themes and need a technical architect to build what Shopify's dashboard can't do out of the box.
Stores doing $10k+/month that need custom discount, bundling, or B2B logic through Shopify Functions.
Brands migrating from Magento, WooCommerce, or a headless stack that has become too expensive to maintain.
Teams whose current theme has been forked so many times that basic changes have become risky.
Founders who want a technical partner around long-term, not a new agency every twelve months.
The theme has become fragile
Every small change breaks something else. Editors are afraid to touch it, and the last three developers left it in worse shape than they found it.
Apps can't do what the business needs
Your discount logic, bundle rules, or B2B pricing don't fit any app on the marketplace, and stacking three apps together makes checkout slow and unreliable.
Growth is being blocked by tech debt
You know what needs to happen next — a new market, a wholesale channel, a subscription model — but the current codebase can't get you there.
Four ways I work with merchants.
Shopify Custom Development
Shopify Functions, private apps, and deep API integrations that extend the platform past what themes and off-the-shelf apps can do.
Shopify Store Development
New builds, redesigns, and migrations from Magento, WooCommerce, or BigCommerce — engineered for editor flexibility and performance.
Growth & Optimization
Speed, technical SEO, and conversion work grounded in your actual analytics — not generic best-practice checklists.
Maintenance & Support
Retained monthly partnership for brands that want a senior technical lead on call — not a ticketing queue.
What you get that a marketplace freelancer or a rotating agency team can't offer.
Business before code
I ask about margin, LTV, and operations before I open a code editor. Technical decisions get made in that context, not in isolation.
One senior engineer
You work directly with me. No account managers, no offshored implementation, no juniors learning on your store.
Built to be maintainable
The code I ship is documented, typed where it matters, and structured so the next person on your team can keep working in it.
Understand. Recommend. Build.
Understand the business
Audit the current stack
Propose the smallest fix that works
Build in short cycles
Cover the edge cases
Deploy without downtime
Stay on for what comes next
Portfolio updates are in progress.
I'm currently documenting Shopify projects that I can publicly showcase. If you'd like to see work relevant to your business, I'd be happy to walk you through recent projects during a consultation.

Built with Shopify's native toolkit.
I prefer scalable custom solutions built on Shopify's native technologies over stacking third-party apps. Cleaner architecture, lower overhead, and full control over the merchant experience.
Common questions before we talk.
Do you take on smaller one-off tasks?
Rarely. My work is scoped for projects and retainers where technical judgment carries most of the value. For a two-hour tweak, a good generalist freelancer is a better fit.
Do you work with Shopify Plus?
Yes. Most of my work is on Plus stores, particularly for teams using Shopify Functions, checkout extensibility, or B2B.
Do you work independently or with development teams?
Both. Depending on the project, I either lead the technical strategy or collaborate with your existing developers and designers. My role is to ensure the Shopify solution is scalable, maintainable, and aligned with your business goals.
How do we start?
A 30-minute call. If it's a fit, I send a written scope and a fixed timeline. If it isn't, I'll tell you and, where I can, point you to someone better suited.
Have a specific technical challenge? Let's talk about the architecture.
A short call is enough to know whether I'm the right partner for what you're building.
