Build, launch, and scale -
all without an internal team.

I help startups and businesses turn ideas into reality - without hiring an internal team. Automated, scalable solutions that ship fast and work reliably.

About

Engineer, entrepreneur, and builder at heart.

I'm Fabien Halaby - a fullstack developer and tech entrepreneur based in Madagascar, building at the intersection of AI, automation, and product engineering.

I believe one focused person with the right tools can build what used to require an entire team. That's what I do for clients - and what I'm proving with Ainga, the AI quality control startup I co-founded.

When I'm not shipping code, I'm studying systems, startups, and the next wave of autonomous AI agents.
