An idea turned into something investors and users can actually click. Scoped tight, built fast, and honest about what's a prototype and what isn't.

What I do
Four ways to get me on board. Pick one or mix them. Every one starts with a call.
Forward deployment
I sit with your customer or your team, find where the product meets reality, and build the glue that makes it land.
On-site in Melbourne, remote anywhere.Contract builds
Extra hands on your roadmap. I pick up a feature, ship it through your review process, and leave the code better documented than I found it.
Flexible hours, AEST-based.AI agent setup
Coding agents tuned to how your team works: repo rules, custom skills, review agents and guardrails. I run my own workflow this way; I'll set up yours.
Fitted to your stack, not a template.02

About
I'm Khairi, a senior software engineer in Melbourne. Pragmatic, optimistic, and six years across a lot of different companies: founding engineer at a community startup, contractor for a $3B fund manager, senior engineer in clinical software, and founder of my own AI product.
I grew up in a family of doctors. Medicine never interested me, and I ended up in healthcare anyway: building clinical messaging at Foxo, then interview prep for future doctors at Deepmock.
TypeScript, React, Vue and Node on AWS are my specialty. But now that AI writes more of the code, the harness is where I excel: the rules, skills, review agents and guardrails that get coding agents shipping good work for a real team.

How it works
01
Touch on
A 30-minute call. You tell me what you're building; I tell you honestly whether I'm the right fit.
02
Plot the route
A short written scope: what ships, by when, and what it costs. No surprises later.
03
Ride it through
I build in the open with regular demos, in your repo and your tools, until it's in your users' hands.
Proof of concept
to production.
Tell me what you're building. Thirty minutes, no deck needed. If I'm not the right fit, I'll say so.
