The work

Matt, also known as zsoXi, combines product and business experience with software engineering, automation and AI agent orchestration. Based in Toronto, he is the founder of Areinum. zsoxi.com is his personal portfolio, with Seraphine as its AI companion and conversational interface.

His work connects interfaces, data systems and teams of agents. The focus is on choosing how a system should work, implementing it and checking the evidence behind the result.

Capabilities

Product and implementation

Connect product decisions and business requirements with working software, from the interface to the data and automation behind it.

Software engineering

Work with TypeScript, React, Python, Rust and PostgreSQL. The portfolio includes engineering examples about runtime validation, concurrency, transactions, retries and idempotency.

Interactive interfaces

Build browser experiences with Three.js, WebGL2, shaders and scroll-driven interaction. This portfolio is one example of that work.

AI systems

Organize agent responsibilities, route work to suitable models, manage context and token costs, and review outputs before accepting them.

How Matt works

Start with the problem and the constraints. Choose the model and tools by the judgement required, the available context and the cost of an incorrect result.

Give agents explicit responsibilities and bounded access. Keep confidential data and secrets behind application permissions rather than relying on a polite prompt.

Separate a proposed solution from an accepted result. Review assumptions, inspect evidence and keep implementation, validation and deployment distinct.
