Hi, I’m David, a product engineer

Let’s work together.

Bring an idea for a product, an existing one that needs work or a feature you want to add. You work with me directly: I help you decide what’s needed, then build it and keep improving it.

What I do

Three ways I can help

Pick the one closest to where you are.

Take your idea or unfinished app through to launch.

Book a call about your product

Sound familiar?

You know what you want to build, but you’re not sure what the first version needs.

You have a prototype or half an app, and need someone to finish it.

You’re being quoted for the whole wish list when you need to know what comes first.

What I’d do about it

Decide what comes first: We agree what people need from the first release and what can wait.
Build the first version: I build the app, portal or tool around the main job people need it to do.
Let you try it early: You get a working preview to click through, question and improve before launch.
Launch and keep improving: I get it ready for people to use, then make improvements based on what happens in practice.

Make your product more reliable and easier to change.

Book a call about improvements

Sound familiar?

Small changes take longer than they should, and it’s hard to tell why.

The developer who built it has moved on, and nobody’s sure what’s safe to change.

You find out something has broken when a customer tells you.

What I’d do about it

Understand what’s there: I learn how the product fits together and find what’s causing the problems.
Fix what’s failing: I work through the broken parts, including checkout and the systems your product depends on.
Make changes easier: I tackle the code that slows development, preserving what already works.
Keep it working: I set up checks for failures and can stay on to look after the product as it changes.

Build the features your customers and team need next.

Book a call about new features

Sound familiar?

Customers need options, trade prices or bookings your product doesn’t support.

Your team retypes the same details into different systems or chases approvals by email.

You want to reach new markets, and the product wasn’t built for them.

What I’d do about it

Add buying and booking features: Custom options, live pricing, trade accounts, bookings and deposits, built into your existing product.
Connect your systems: Details move between systems, with checks along the way and an alert when something doesn’t go through.
Build tools for your team: Shared documents and approvals, or AI assistants that draft replies and changes for someone to approve.
Reach new markets: Languages, mobile apps and local payment methods for the customers you want next.

How it works

From the first conversation to launch

You work with me directly, from the first call to launch: no account managers, no handoffs.

Talk it through
A free 30-minute video call about what you need and what’s in the way.
Get a written plan
After the call, I’ll send what we’ll do first, what can wait and what I need from you.
Try it early
You get a preview link to click through yourself: something real to question and improve.
Get a weekly update
Each week: what’s shipped, what’s next and any decisions I need from you.

After launch

Hand over or keep going

You get the code, access and notes your next developer needs, or I stay on each month to look after it.
