Where I can help

For your business

A new site, a better store, or a specific problem in the one you already have.

New websites & stores

Plan and build a business website or online store, with a way for your team to manage its content.

Discuss a new site

Upgrades & integrations

Improve an existing site, update its CMS, or connect the systems behind ordering and day-to-day work. Start with the part that needs attention.

Discuss an upgrade

For agencies & teams

Development support for your designs, an existing codebase or a project that needs an experienced pair of hands.

Keep the client relationship and your delivery process. I can take responsibility for an agreed piece of the build.

Before we build

Start with the problem and the result you need.

We’ll work out what needs to change and what can stay. That might be a new site, a contained upgrade or development support for your team.

Before committing to a build, we’ll agree the deliverables, timing and cost. We’ll also cover who maintains the result and what support is needed after handover.

Tell me what you’re working on

Who you’ll work with

I’m Siyu, also known as David.

A senior full-stack engineer in Auckland, with about a decade of experience across business websites, e-commerce and software products.

Read my writing

I like to understand a product before I change it.

I’m currently at Forsyth Barr and lead engineering at MageBinary part-time. Previously, I worked on Vello and ezyVet at IDEXX, contributing across the stack and leading feature delivery. My project work also includes New Zealand retailers and the FernMark licence website.

You’ll speak with me about the brief and the technical decisions. I’ll be clear about the work I can take on and how it fits with your team.
