I build the infrastructure layer between raw data and useful knowledge — from bare-metal Kubernetes clusters to the ML pipelines and UI systems that make data accessible.

38-asset knowledge graph construction platform with MCP-contracted LLM extraction, dual-write KG (PostgreSQL+pgvector + Neo4j), GPU-accelerated transcription, and cross-source entity resolution running on a 5-node Talos cluster
- 38 Dagster assets across 4 code locations (12 congress, 10 media, 13 open-leaks, 3 knowledge-graph) with Bronze/Silver/Gold/Platinum medallion architecture
- 3-package LLM contract validation system with MCP-enforced structured output, 9 ConfigMap-mounted prompt templates, and 198 tests at 97% coverage
- GPU-accelerated transcription: dual backend (OpenVINO + faster-whisper) with automatic CPU fallback
- Speaker diarization with pyannote + word-level alignment
- LLM-based NER and qualified S-P-O assertion extraction with negation/hedge detection
- Cross-source entity resolution (EDC framework) across 4 domains
- Dual-write knowledge graph: PostgreSQL+pgvector + Neo4j
- 22 Prometheus metrics across 8 subsystems with 32 Kubernetes manifests
- QSV AV1 hardware video transcoding for ultra compression
- 13-page Streamlit data explorer with asset browser, semantic search, knowledge graph viz
Production Talos Linux Kubernetes cluster with dual GitOps (Flux + ArgoCD), full LGTM observability stack, multi-cluster connectivity via Nebula mesh, and 30+ infrastructure components
- 5-node Talos Linux immutable cluster (1 control plane, 3 workers, 1 GPU node with Intel Arc) plus AWS k3s node for hybrid multi-cluster
- 30 infrastructure components under Flux Kustomization: Cilium CNI with ClusterMesh + Hubble, Traefik ingress, cert-manager, Authentik SSO, External Secrets with 1Password Connect
- Full LGTM observability stack: Mimir, Loki, Tempo, Alloy, OTel operator, Grafana Operator with 20+ custom dashboards, plus Graylog/OpenSearch/FluentBit
- Dual GitOps: 30 Flux Kustomizations for infrastructure, ArgoCD with image-updater for application workloads
Kubernetes operator that watches Widget CRDs across namespaces, reconciles them into Homepage-compatible ConfigMaps, and serves a Gin REST API with WebSocket push for real-time dashboard updates
- Custom Widget CRD (gateway.catalyst.io/v1alpha1) with kubebuilder markers, status subresource, health tracking, and credential SecretRef injection
- Reconciler watches Widgets cluster-wide, groups by category labels, and writes a merged services.yaml ConfigMap every 30s
- Gin REST API on :8082 with gorilla/websocket push — clients get live widget state without polling
- Credentials stay in-cluster: SecretKeySelector refs resolve into HOMEPAGE_VAR_ env placeholders
Cyberpunk-themed React component library shipping 50+ components, 8 synthwave themes, a D3.js ForceGraph engine with 4 layout algorithms, and a full observability stack — all tree-shakeable ESM exports
- 50+ components across 33 Radix UI primitives, 14 advanced components (ForceGraph, CodeBlock, Timeline, ThreeJS), and specialty cards including a print-ready RPG character sheet resume
- 8 synthwave CSS themes (Catalyst, Dracula, Dungeon, Gold, Laracon, Nature, Netflix, Nord) with 6 cyberpunk effect layers: glow, scanlines, border lasers, gradients, keyframe animations, and debug overlays
- D3.js ForceGraph engine with 4 layout algorithms (force-directed, Dagre, ELK hierarchical, community detection), orthogonal edge routing, and localStorage position persistence
- 133 tests at 99% coverage with Vitest + Testing Library, enforced via CI alongside automated Storybook deployment to GitHub Pages
Native macOS menu bar app for GitHub PR management — floating NSPanel dashboard with urgency scoring, inline diff viewer, quick review actions, and AI-powered PR synopses
- LSUIElement menu bar app with NSPanel floating window (statusBar level, canJoinAllSpaces) anchored below status item with neon glow pulse via Core Animation
- Carbon Events API global hotkey (Cmd+Shift+Option+P) registers system-wide via RegisterEventHotKey with user-customizable key combos
- GitHub GraphQL v4 client with ETag-based conditional requests, SHA256 cache keys, LRU eviction, and exponential backoff with Retry-After
- macOS Keychain Services integration storing GitHub PATs per-account with kSecAttrAccessibleWhenUnlockedThisDeviceOnly
