What I build
13 shipped repositories spanning AI platforms, safety systems, financial intelligence, and systems research. Click any card for the full case study.
- Decomposes user intent into deterministic task graphs
- Routes to SLMs (temp=0) or Claude via YAML-driven pre/post-execution policies
- HMAC-SHA256-signed immutable audit trails; cost tracked per team
- No autonomous agents - deterministic execution only
- Local reverse proxy (Go 1.26) intercepting Claude Code at :7777
- 13-step pipeline: SHA256 dedup, bash-result caching (2h TTL), image stripping + OCR
- 4-tier memory manager + BadgerDB knowledge graph with hybrid ranking
- Measured 67% token reduction on 635-request session (295K -> 98K tokens)
- Local fine-tuning workbench for 135M-7B models (Python)
- Hardware-tier classification probes actual RAM/VRAM - refuses jobs that won't fit, no silent OOM
- MLX-LM primary on Apple Silicon, CUDA via accelerate launch, CPU fallback
- 30 RAM-tagged models, 6 export formats (GGUF/MLX/CoreML/ONNX/TFLite/Ollama), 101 unit tests
- Production Bloomberg alternative - 282 features across 30 tabs
- Real-time charting (35+ indicators in Web Worker), multi-LLM streaming (Claude 3.5/Gemini 2.0/GPT-4)
- 3,000-path Monte Carlo optimizer; institutional data (13-F/Form 4/Congress trades/dark pool)
- 5-guard self-learning trading bot + SHA-256 hash-linked audit chain; 335/335 tests, 0 TS errors
- YOLOv8m TensorRT FP16 + ByteTrack at 15 fps/camera (1,500 fps cluster on 3-4 RTX 4090s)
- Rolling 60-sec FFmpeg segment buffer for stream-copy clip extraction (<500ms)
- Ed25519 chain-of-custody signing for tamper-proof evidence
- OSHA Form 300/300A auto-export, DART/TRIR, ITA e-submission; 30+ API routers
- 25 open data sources (USGS, GDACS, NASA FIRMS, ACLED, aviation, maritime, weather, ocean) into unified PostGIS incidents
- Two-stage Claude pipeline - Haiku extraction then Sonnet narrative generation
- Atomic Redis token budgeting (490K/day, 45 summaries/day, 5/session) with layered degradation
- Geohash cache reuse; LibreTranslate for multilingual incident normalization
- 5 workspace crates (~5K LoC): no_std microkernel with SPSC ring bus
- Neural HAL (NPU/GPU runtime via JitPatchContext); USDF vector-addressed storage with VFS bridge
- Ring-0 agent swarm (Synthesis/Orchestrator/Curator/MemoryOptimizer/Janitor)
- SWIM-style gossip cluster with RDMA compute credits; not bootable - 28 issues documented
- 8 connectors: SAP OData v4 OAuth2, Ariba, CDK, Manhattan, Snowflake, TMS, Warranty, Demand
- 13 SQLAlchemy tables; APScheduler for 15-min ingest, 6am daily, Monday weekly jobs
- Z-score anomaly detection (60d lookback, z>=2 warning / z>=3 critical)
- 14-day demand forecast (40% trend + 60% MA); deployed on Render
- Decentralized P2P AI compute grid - developers pool local GPU hardware (Ollama/vLLM) into a unified async API gateway
- EIP-191 Ethereum wallet auth - guild admission verified on every WebSocket connect via admin-signed credentials
- Smart dispatch matches consumer requests to least-loaded node; 3-layer failure handling with APScheduler requeue sweep
- Compute credits settled hourly via PL/pgSQL batch - one transaction per hour instead of a write-lock per inference
- Intraday mean-reversion strategy driven entirely by Claude Code via a brokerage MCP server - no compiled trading engine
- Strategy config, session prompts, and cron runner; every decision logged to trade history and a strategy feedback log
- Phase-gated: signal validation (no orders) by default, manual promotion to live trading only after logged data supports it
- Localhost dashboard with bounds-checked, tighten-only parameter API and timestamped strategy backups
- GPS-based landmark audio tour app - React Native (Expo) frontend, Node.js/Express + PostGIS backend
- Offline content pipeline: Wikipedia/Wikidata facts -> Claude drafts sourced narration -> TTS synthesis, admin-reviewed before publish
- Live geofence triggers (250m radius) play narration automatically; every fact links back to its source
- Route scoring blends travel time, landmark count, and a crowd heuristic across 2-3 candidate routes
- Single Go binary merging a token-optimization pipeline with a policy/audit governance layer into one agent platform
- Autonomous agent loop with sandboxed code execution and web fetch, plus a web chat UI and terminal REPL
- Multi-provider LLM aggregation gateway behind one API endpoint - price/health routing, automatic failover, streaming translation, prepaid billing
- Atomic escrow billing, concurrency-tested (100 racing debits, zero overdraw); hash-chained tamper-evident audit log
- Turns a job posting into a personalized ~100-question interview study guide, cross-referenced against real interview discussion from public, terms-compliant community APIs
- Deliberately avoids sites that block automated access - treated as an authorization boundary, not just a scraping tradeoff
- Model-routed answers: a fast model for resume-grounded behavioral responses, a stronger model with capped web search for technical/system-design claims
- Mock mode by default (built-in question bank, no API key required); live mode degrades gracefully per data source
