Tim Baird
I build production systems in XRPL and AI/LLM. Currently shipping Full Circle MUD — a live multiplayer game running on-chain transactions, multisig wallets, and LLM-driven content pipelines.
About
Over a decade in software — building it, and teaching it. My most recent significant technical work is Full Circle MUD: a live game running XRPL multisig and NFT metadata, LLM pipelines with embeddings and vector stores, and a horizontally-scaled Evennia/Django backend.
In addition to technical work, seven years teaching software engineering, database design, and programming at Swinburne University — which is where you really learn whether you understand something.
Looking for XRPL or AI/LLM engineering roles. Open to senior crypto, Solidity, or general architecture work as stepping stones. Remote only. Currently Melbourne, globally mobile.
Full Circle MUD
Featured · OngoingA live multiplayer online game built on Evennia/Django, integrating XRPL blockchain and AI/LLM systems. Solo development. The architecture priority has been genuine decoupling — game subsystems communicate only through well-defined interfaces, enforced via bespoke Python libraries.
- XRPL on-chain integration. Multisig transactions, NFT metadata, supporting APIs for token operations.
- AI/LLM pipeline. OpenRouter and OpenAI API integration; embeddings stored in vector databases; a private LLM test-bot harness for automated dialogue regression testing.
- Horizontal scaling framework. Engineered to distribute Evennia's single-threaded Twisted Reactor across multiple instances sharing a vertically-scaled Postgres backend.
- Library architecture. Bespoke Python libraries enforce minimal coupling between game systems; each addressable as an independent concern.
- Operational tooling. XRPL wallet management interface (private repo) for internal use.
Other Work
Personal projects
Google Calendar API integration for the Go High Level CRM platform; OpenZeppelin-based Solidity smart contracts deployed on Polygon (FCM's original blockchain layer before the XRPL pivot); AI/LLM learning exercises and code samples created for students; additional projects in Oracle PL/SQL, C#, and JavaScript.
Tech Stack
Tools picked up as the work demanded. Most languages and frameworks are first principles in different costumes — I optimise for the problem, not framework loyalty.

(Keeping them off the public page protects both my direct contact and my referees' details from scrapers — Nigerian princes don't fill out forms.)
