What I leave out
Most of the work is deciding what to leave out. A few decisions from products I've led: switch between what was there and what shipped.
A separate screen for every contact's notifications
One sheet, opened from the contact, closed with a tap
"New monthly run"
"New monthly invoices"
Pay again while the first charge is still being checked
One payment at a time, until the bank confirms
Patch the old app for one more year
Build the new app alongside it, switch in one release

About
I've spent the last ten years building SaaS products for racing, education and printing businesses, leading small engineering teams through releases, payments, mobile apps and design systems.
I use AI the way I'd work with a new teammate: useful every day, always reviewed, never left alone with the decision.
Leave things out
Every screen, field and setting costs the person using it.
Use your users' words
If they say "monthly invoices", so does the product.
Be careful with money
Payments that can't charge twice. Upgrades users never notice.
AI, with guardrails
One model writes, another reviews, a person decides.
Services
Fractional tech lead
Senior technical leadership for a small team that doesn't need it full time yet.
Modernise without stopping
Upgrade an ageing app or backend while it keeps serving customers.
Build and ship
Web and mobile products from first version to production, payments included.
AI with guardrails
AI in your team's work, with review, limits and a clear record of what it did.
A small number of projects at a time. Remote from Vietnam, for teams in Australia, Europe and Vietnam.
