Ship with conviction.
Built with AI inside.
I'm Lachlan — a senior product engineer who helps founders ship AI-driven products and internal tools that pay for themselves. Calm decisions, honest scope, real outcomes.
— Trusted by founders building things that matter —
Four convictions that show up
in every engagement.
These aren't slogans on a sales deck. They're the calls I make every day when nobody's looking.
- 01
ROI-driven
Decisions that pay for themselves
Every line of code earns its keep. I make calls with the product’s P&L in mind — not the resume.
How I think about it → - 02
Ship with confidence
Ship without the white-knuckle releases
Small reversible steps, real-world tests, observability from day one. The team trusts the deploy button.
How I think about it → - 03
Integrity
Honest scope, honest tradeoffs
No invented requirements, no padded estimates, no quiet shortcuts. If it can’t be done well, you hear that first.
How I think about it → - 04
AI in the build
AI as the implementation, not the slide
I build with AI inside the product and inside the workflow — only where it earns the trust to be there.
How I think about it →
Three lanes. One operator.
AI integration & automation
Embedding AI into the product and the workflow — where it earns its keep.
Product engineering & fractional CTO
Senior product engineering, embedded — without the hiring runway.
Custom internal tools & dashboards
Bespoke ops software your team actually uses, shipped in days not quarters.

What it feels like to work with me.
— on shipping with confidence
“Lachlan made every step feel obvious. He understood what we needed before we'd finished explaining it, and shipped the product we needed to ship. He has a rare knack for making technical work feel small.”
Sohail Abdulla
CEO, MapYourFinance.com
— on integrity
“Lachlan led our CallRail to Twilio migration with the kind of calm, methodical clarity that just makes you trust the call. The savings hit immediately, and we kept the per-client flexibility without the complexity I'd braced for.”
Will Horton
CEO, Lasting SEO
— on ROI
“We were burning 15 hours a week on debt collection admin. Lachlan built us a bespoke SMS distribution system that cut that by 80% in four days. Four days. It paid for itself before the invoice landed.”
Pat Watson
CEO, ClickMeCars
One call. Honest answers. No deck.
A 30-minute call. I'll ask honest questions, and you'll get honest answers about whether I can help — and whether you should hire me at all.
