About
I take AI from an idea to a product people use.
I'm Stefan Nio, co-founder and CTO of Interlinked Global. I work across the whole product: what it should do, how it is built, and where a model belongs in it.
I have done it once end to end. I built bizsec.io, a workspace for Singapore corporate secretary firms, and shipped it to production on my own. Its beta users shaped it.

What I'm looking for.
A role taking AI and agent systems from a promising demo to a product people rely on, at a company of any size. Founding engineer and product engineer are the titles closest to how I work. I would rather own an outcome than one layer of the stack.
Two kinds of work draw me, and at bizsec.io I found them equally rewarding. One is owning a product from a user's problem to something people use, and keeping it running after launch. The other is making the AI inside a product good: using current models and agents where they improve an answer or a decision, and leaving them out where plain code is more reliable.
I work remotely from Australia and will relocate anywhere for the right role.
How I work
Agents write more of the code. I still run the process.
I use coding agents every day. The skill that matters most is still the old one: breaking a problem into small, clear tasks. That is what keeps a product reliable and easy to change, whoever writes the code.
As models improve I hand agents more of the work. What earns that trust is a codebase clean enough for an agent to follow, and checks it can run to prove its own work. A person still reviews every change before it ships, and I cap how much agent work is in flight so the review stays real.
I write down the decisions that matter. bizsec.io has 34 architecture decision records, and two of them reverse earlier ones. The case study walks through both.
