👋 David Wetmore — Projects & Current Work

🚀 I build practical, well-documented software that blends AI-enabled apps with reliable deployment workflows.

What it is: An Argo CD app-of-apps control repo that bootstraps and manages multiple workloads from one declarative entrypoint.
What it does: Defines child Argo CD Applications for services like chatbot, notes-app, GPU observability, space-invaders, and cmatrix; keeps cluster state converged to Git.
Why it matters: Demonstrates platform-level GitOps orchestration and how to scale from single apps to a managed portfolio with consistent deployment patterns.

What it is: A deployment-focused repository for running the chatbot stack on MicroK8s via Kubernetes manifests and overlays.
What it does: Manages environment-specific configuration and rollout behavior for OpenWebUI + Ollama, enabling repeatable local cluster deployments.
Why it matters: Separates delivery concerns from application code and shows production-style configuration discipline even in homelab/dev environments.

What it is: A FastAPI-based chatbot backend project.
What it does: Exposes API endpoints and service logic that can be deployed independently or integrated into larger conversational systems.
Why it matters: Highlights API-first backend design and provides a clean Python service foundation that can evolve with model providers and product requirements.

What it is: A containerized browser-accessible cmatrix experience built with Xvfb, x11vnc, and noVNC.
What it does: Runs a terminal graphical workload in Kubernetes and serves it over HTTP so users can access it from any browser without local X11 setup.
Why it matters: Demonstrates practical remote GUI packaging, container runtime behavior, and service exposure patterns for non-traditional workloads.

What it is: A pure GitOps observability stack for NVIDIA GPU environments on MicroK8s.
What it does: Deploys and configures DCGM exporter, Prometheus, Grafana, and logging components with custom dashboards and metric curation.
Why it matters: Shows end-to-end GPU telemetry implementation and operational monitoring maturity, which is critical for AI/ML reliability and capacity planning.

What it is: A FastAPI + PostgreSQL notes service with Kubernetes deployment assets and tests.
What it does: Implements CRUD APIs, health/readiness endpoints, environment-driven DB backend selection, and deployable manifests for GitOps workflows.
Why it matters: Demonstrates full-stack service engineering fundamentals: app logic, persistence behavior, test coverage, and deployment readiness.

What it is: A Pygame game project adapted for containerized/Kubernetes execution.
What it does: Provides an interactive game workload with deployment manifests and runtime tuning for consistent behavior across environments.
Why it matters: Proves that interactive apps can be treated with the same delivery rigor as backend services, strengthening platform versatility.

What it is: The portfolio/meta repository that documents and links the project ecosystem.
What it does: Serves as the primary index for projects, current engineering focus, and public-facing technical narrative.
Why it matters: Creates a single source of truth for project discovery and communicates architectural intent across the portfolio.

✅ argocd-apps (main): latest commit 77ee9ae updates cmatrix deployment to localhost:32000/cmatrix:novnc2.
✅ gpu-observability-gitops (main): latest commit f78ad0a expands GPU dashboard and aligns panels to supported DCGM metrics.
🛠️ notes-app (codex/fix-database-selection-logic-and-logging): DB selection/overlay improvements in progress with local staged changes.
🧹 chatbot-gitops (main): migration cleanup state (dev-ollama patch files currently deleted locally).
📌 dwetmore (main): portfolio repo with chatbot and notes project mirrors.
