Isaac Lyons-Barney
CS grad from Canada. I work with Kubernetes and Terraform for infrastructure, and with AI agents, embeddings, and LLM APIs. Looking for work where I can contribute meaningfully and continue to learn.
See what I builtFeatured Project
Rhizome
A semantic Wikipedia traversal tool built on vector embeddings. You give it a starting concept, and it walks through semantically related Wikipedia passages using epsilon-greedy exploration: configurable exploration parameters (like temperature) let you tune how focused or tangential the walk is. Uses Qdrant for vector storage. Users can create their own embeddings for custom Wikipedia domains. The output is a chain of cited Wikipedia passages, each one leading into the next.
Indexed ~39,000 Wikipedia articles across 6 domains — Modernism, Postmodernism, Continental Philosophy, Frankfurt School, Aesthetics, Literary Theory — producing 832,167 vectors.

Experience
Systems Officer II at Ontario Public Service, Jan–Aug 2024
Built enterprise back-end services for government web applications — Java/Spring for AgriSuite and FRI, C#/ASP.NET features alongside. Implemented end-to-end test automation with Playwright and Azure, running environment-specific executions with centralized reporting and saving 40+ hours per year. Agile team with shared CI/CD workflows.

Rhizome is the anchor. More projects will slot in here as they mature.
AI / Embeddings
Rhizome
Wikipedia traversal using epsilon-greedy search over vector embeddings. Temperature and epsilon are configurable to control how explorative or focused the walk is. Users can build their own corpora for different Wikipedia domains. The output is a chain of cited Wikipedia passages, each one leading into the next.
Game Development
Dungeon Crawler
3D dungeon crawler video game built by a team of 6 for a university project. Led the team as project manager, overseeing architecture and deliverables.
Infrastructure
Home Cluster
Four-node Kubernetes cluster on bare metal, managed declaratively with Terraform and ArgoCD. Infrastructure declared in code. If the hardware were destroyed tomorrow, the cluster would still exist, ready to rebuild. Self-hosts a music server, photo gallery, movie library, git forge, and more. Prometheus + Grafana monitoring.
Infrastructure
Where I Deploy Things
Self-hosted on bare metal. Four-node Kubernetes cluster managed with Terraform and ArgoCD, the full architecture declared in code. If the hardware were destroyed, the cluster would still exist, ready to rebuild. Runs git hosting, media streaming, compute workloads, and more. This dashboard is live.
