Sound
familiar?

What merchants tell me before we start.

01

“Your store needs a feature no app quite gets right.”

You’ve tried the App Store, and every option is close but not what your customers need.

02

“You’re stacking monthly apps that don’t work together.”

Costs keep rising, and the apps still leave gaps you patch by hand.

03

“Orders, inventory and fulfilment are copied between systems by hand.”

Manual work eats hours every week and causes costly mistakes.

04

“Your last developer took days to reply.”

You need fast turnaround and someone who answers directly.

Built for
revenue.

The relevant proof: payments, integrations and production software.

01

Payments &
integrations

As CTO of TravelSpoken, I built a full-stack platform spanning booking, payments, social content and third-party integrations.

Technology contributed to a multi-million-dollar fundraise.

02

Production
software

End-to-end ownership of production apps: architecture, APIs, integrations, deployment and performance.

40+ production apps shipped.

03

Production
at scale

As a senior full-stack developer on a high-traffic consumer platform, I built features, shipped deployments and maintained the live apps and production database.

2M+ sign-ups · 1.1M+ active users · 7M+ entries.

Christopher Walsh, senior full-stack developer in Toronto

You work directly with me, so changes ship quickly and nothing gets lost between a salesperson and a developer.

6 years across the full stack — mobile (iOS/Android), web, backend, cloud and AI — including deploying and maintaining production apps and databases for 1.1M+ active users. That means fewer handoffs, faster decisions and one person accountable for the result.

Clear from
day one.

Start with the business goal, define the right build, then move through launch without unnecessary complexity.

01

Strategy

Find the change most likely to lift revenue or save hours each week.

02

Architecture

Decide between theme work, a custom app or an integration, planned around your existing apps.

03

Build

Develop on a duplicate theme or development store so your live store keeps selling.

04

Launch

Ship, verify orders and checkout, then iterate based on real sales data.

$5K–$20K

Typical Shopify projects run $5K–$20K. Theme improvements on an existing store sit at the lower end. Custom apps and integrations with warehouse or accounting systems sit higher. You get a fixed scope before work starts.

Straight
answers.

The questions people ask before booking a call.

How long does a typical project take?

Theme changes and small features move quickly; custom apps and integrations take longer. You get a timeline after the strategy call, tied to a defined scope.

How fast can we start?

Quickly. Book a strategy call and we can usually talk within a few days. If we’re a fit, you get a written scope and estimate shortly after, and work starts as soon as you approve it — no long sales process.

Will working on my store affect live sales?

No. Work happens on a duplicate theme or a development store, and changes go live only after you have reviewed them.

Do you build custom Shopify apps or just themes?

Both. Theme work handles storefront changes; a custom app is the right call when you need new functionality, admin tools or integrations that existing apps don’t cover.

Do I own the code?

Yes. You own the code and the repository, and accounts are set up in your name. You are never locked in to working with me.

How do we work together day to day?

You work directly with me — no account manager and no agency handoff. You get regular progress updates, working builds to review, and quick answers when decisions come up.

What if I only need a small feature, not a full platform?

That’s fine — not every project is a full build. A single feature, an integration, a fix or a review of existing code can be scoped and quoted on its own. The strategy call is free either way, so it costs nothing to ask.

Do you sign NDAs?

Yes. I’m happy to sign your NDA before you share details — send it over before or after booking. Your idea and information are kept confidential either way.

What does something like this cost?

Typical Shopify projects run $5K–$20K. Custom apps, integrations and complex pricing logic are the biggest drivers. You get a clear estimate after the strategy call.
