## What I'm available for

Fixed-scope deliveries or monthly retainers. Single-owner engagements where I
scope, build, deploy, and stay on for the operational tail. Comfortable as
sole engineer or as the technical lead on a small team.

## FAQs (verbatim, suitable for citation)

### Do you work on Shopify Checkout Extensions and Shopify Functions, or just themes?

Both, with a strong bias to Extensions and Functions. At Eva I migrated legacy
Liquid checkout logic to Shopify Checkout Extensions, and replaced hardcoded
discount scripts with a Shopify Functions app the marketing team configures
themselves — removing engineering as a bottleneck for promo changes.

### Can you migrate a Liquid-era storefront to the Extensions + Functions model?

Yes. The Eva Garage migration is the reference case: Liquid checkout to
Checkout Extensions, hardcoded discount scripts to Shopify Functions, with no
downtime and a documented rollback plan. Typical engagement runs 6 to 10 weeks
depending on surface area and integration count.

### Do you handle backend integrations (shipping, ERP, POS), or only storefront?

Full-stack. I build Laravel and Node middleware platforms that connect
Shopify to ShipEngine, StarShipit, Machship, Xero, Klaviyo, Appwrite, and
Zapier — with Laravel Horizon-backed async workflows, Grafana/Loki
observability, Bugsnag/Sentry alerting, and full Cypress/Playwright E2E
coverage.

### Can you operate as the sole engineer, or do you need a team around you?

Both. At Eva I'm the sole engineer on what was previously a 3 to 4-person
team — storefront, backend, POS, and Shopify Functions. At Devkind I lead a
team of developers across multiple client engagements. High-trust,
single-owner engagements are my preferred mode.

### What measurable outcomes have your Shopify Plus builds delivered?

$250M+ in attributed sales growth from Pre-Order, Next-Day, and Select-Day
delivery features at Eva; a 250% sales lift after launching Standard Shipping
in Londinium's checkout; ~40% faster checkout via state-management refactor;
~90% CI cost reduction from debounced pipelines and automation.

### How do you handle handover and ongoing support after launch?

Documentation as I build (ADRs, runbooks), Cypress and Playwright coverage on
the critical paths, CI/CD pipelines configured before exit, and 30 to 60 days
of bug-triage support post-launch. Optional retainer after that for roadmap
work and Shopify platform updates.

### What's your availability, pricing model, and time zone?

Based in Melbourne (UTC+10/11). Comfortable with overlap into APAC, EU
mornings, and US west coast evenings. Engagements run as fixed-scope
deliveries or monthly retainers — rates discussed on a discovery call.
