Michael Limberger

Senior Web & Linux Administrator

hello@techalicious.academy

Michael builds and maintains web applications, Linux servers, and AI systems for the University of Toronto's Faculty of Dentistry. With over 15 years of Perl expertise, he has a track record of solving real-world problems with practical, maintainable code.

He built the RAG Proxy system presented at TKF 2026: a local AI layer that searches 94 dental policy documents and generates cited answers without sending a single byte of data to the cloud. The entire system runs on one Mac Studio using open-source tools.

The meetup

Michael runs Techalicious-Club, a GTA meetup for tech hobbyists covering AI tools, Linux, privacy tech, and self-hosting. The meetup is welcoming to all skill levels. New folks often get the most out of it, because the questions they ask reveal where the documentation is broken. That's usually the most useful part of the night.

Sovereign AI

Michael is a strong advocate for sovereign AI: local, private, and free from vendor dependency. In his view, healthcare IT needs to own its intelligence, not rent it.

Personal Projects

Beyond the day job, Michael builds tools and systems that scratch his own itch. These are personal projects, built on evenings and weekends, driven by curiosity about how AI, systems programming, and language design can work better together.

TOAD
Terse Orchestration And Dispatch, a symbolic systems language
A programming language Michael designed and built from scratch in Rust. TOAD uses zero English keywords for logic. Every control structure is a symbol. It's a conductor language: it handles variables, control flow, regex, and system execution while delegating heavy lifting (networking, parsing, databases) to external programs via a polyglot bridge system. TOAD scripts can embed Perl, Ruby, and Python inline, passing typed data between languages through a JSON bridge. Compiles to a single static binary with no runtime dependencies.

System Commander
AI-powered sysadmin agent, heuristics first, LLM second
An AI-powered sysadmin agent built in Perl/Mojolicious. Uses a 5-layer heuristic decision tree (regex pipeline) as its primary brain, with a local LLM (Ollama) as a fallback normalizer for ambiguous inputs. Includes a semantic memory system (Brain.pm) with SQLite + PDL vector search, the same engine that powers the RAG Proxy. The latest version (v3) integrates the brain CLI for persistent knowledge across sessions.

Battle-Grounds
Top-down 2D team PvP brawler with fantasy combat and six character classes
A standalone 4v4 team deathmatch game built in Godot 4.6 with GDScript. Two teams (Blue vs Yellow) battle across a map populated by hostile NPCs. Six character classes (Demon, Ent, Lich, Mushroom, Beholder, and Lizardman), each with team-specific special abilities (burn vs ice slow, lifesteal vs zombie spawn, dodge vs double attack). Neutral Soldiers and Champions roam the map dropping healing potions, power potions, and thunder wands. First team to 25 kills wins. CPU backfills empty slots with bot AI. LAN multiplayer planned.
