XINI

Xini, systems engineer

I build complete, self-hosted products with modern AI woven in.

MSc Artificial Intelligence, St Andrews. BSc Computer Science, Warwick.

01

Whole systems, built solo.

I take ambitious ideas all the way to production on my own: real-time 3D, multiplayer backends, data, infrastructure and the interface people actually use.

Full stack, real-time 3D, multiplayer

02

AI that does real work.

I build AI into products where it earns its place: agents that act on real systems, MCP servers that give models real tools, and local models when the data should stay put.

Agents, MCP servers, local models

03

Secure by default.

I self-host what I build and design for Zero Trust, with OWASP practice and PII redaction there from the first commit.

Self-hosting, OWASP, Zero Trust
