About

An engineer.
A founder.
Always curious.

I’m Bulela Tshulisi, a software engineer and founder of Xiaoyao Systems. I value curiosity, freedom, and giving things a try.

I am a software engineer and independent builder interested in AI, learning, software products, and what happens when making software gets cheap enough for one person to ship the thing.

Java/Spring backend engineer by profession. Building Guessor, Axioms, Arkly and whatever idea refuses to leave me alone.

More about me

Engineering

Building software that has to keep working.

I work primarily on backend systems, integrations and production software using Java and Spring.

The professional work is less about a stack list and more about a habit: take an ambiguous system, find the real constraint, and change it without breaking what already depends on it. The notes below are themes rather than a resume. Employer systems stay unnamed on purpose.
