Engineering Experience & Systems Architecture
Lead AI Infrastructure Architect · krusch Systems Lab
2024 – Present · Los Angeles, CA
  • Unified 7-Pillar MCP Stack, #1 Official DolphinBench & ICLR 2026 BEAM Validation (krusch-stack v1.0 & krusch-context-mcp v2.0): Authored npx krusch-stack init (39 MCP tools, -68.5% BM25 schema bytes, INV-STACK-10 2PC action harness cutting duplicate MCP calls 10→0 w/ +20.0 pp recovery), krusch-git, krusch-fs-mcp, and krusch-context-mcp (82★). Across 14 Official gpt-5.6-sol DolphinBench runs (8,400 traces, 5 families, $0.00 0o444 SovereignMemoryStore), achieved #1 Overall 91.17% (547/600 @ $24.54, 35.38s, +20.50 pp above #1 Mem0 70.67% @ $96.21; 89.17% Medium; 96.17% Oracle@14, 4.19x LBF=4+; 8 queued archives, UUID c047b063-822c-49fb-8b36-27c3763d6ca7) and #1 Open-Weights 54.17% (325/600 Gemma 4 31B UUID 288671ad-… & 42.67% local 30B @ $0.00, beating all 8 non-Luna cloud baselines), plus 2,000/2,000 BEAM (93.00% 10M IE).
  • Transactional 2PC Coding Harness & Policy Floor (krusch-coding-harness): Engineered a PostgreSQL-backed coding harness enforcing import-frozen policy floors, shell-deobfuscation checks, truncation-poisoning breakers, verify-on-stop outer loops, and Bubblewrap (bwrap) sandboxes committing SHA-256 diffs via <32ms 2PC journals—achieving 0.00% ASR across 1,046 ETH SpyLab AgentDojo episodes and 51.56% on Aider Polyglot (2.64x lift).
  • Autonomous SRE, Wave-4 QLoRA+DPO & #1 Cascade Routing (jean-sre, krusch-cascade-router, krusch-companion): Built a 24/7 cross-family Referee pipeline auditing 88 targets and publishing 18,131 test-verified SFT + DPO rows across 7 splits (krush420/sovereign-code-audit-sft) to train 4-bit MXFP4 120B (39.50% DolphinBench), 30B MoE (93.36% token acc; 42.67% DolphinBench), and 8B Edge (18.33%, 15.7x DolphinBench lift over 1.17% stock) Wave-4 QLoRA+DPO adapters on 96GB Blackwell G4, alongside <15µs CPU cascade routing (#1 across RouterArena 80.72% @ $0.21/1K, LLMRouterBench & RouterBench), krusch-companion, and 26 published architecture whitepapers.
Lead Systems Architect & Creator · KruschBiz Contract Intelligence
2025 – Present · Los Angeles, CA
  • Confirmed-Edge Precedence Graph & Draft Isolation: Engineered a transitive DAG resolver with cycle detection and unexecuted draft isolation (execution_status='draft'), guaranteeing proposed relations remain advisory and unexecuted drafts cannot defeat executed agreements.
  • The Join (Contract vs. Statute Compliance) & Gateway MCP: Architected cross-domain compliance evaluation (POST /conflicts/contract-vs-statute) testing controlling contract clause slots against statutory floors/ceilings, exposed via a 5-verb Gateway MCP router (<450 prompt tokens) with immutable ResolutionTraceRecord audit logs.
Principal Architect & Founder · KruschLaw & KruschNexus Platforms
2025 – Present · Los Angeles, CA
  • Span-True Document Ingestion & 0.00% False Support Rate RAG: Architected an air-gapped legal RAG engine (KruschLaw) and 7-parser Poppler TSV ingestion spine (KruschNexus, 100% citation accuracy & 96.2% span precision) indexed with 8K-context snowflake-arctic-embed2 (1,024-dim), pairing two-pass proposition entailment with strict citation stripping to achieve a 0.00% False Support Rate.
  • Versioned Statutory Graph & Cryptographic Purge: Built multi-hop statutory preemption DAG resolvers with first-class as_of_date temporal traversal, 16 deterministic Authority Packs, programmatic explain_why_not_controlling diagnostics, and verifiable SHA-256 tombstone purges.
Bare-Metal AI Cluster & Infrastructure Architect · Krusch Sovereign Fleet Operations
2023 – Present · Los Angeles, CA
  • Multi-Family 5-GPU Cluster & 96GB Blackwell Burst Tier: Designed and operate an 8-node Linux cluster (Dual Xeon 40T, 144GB+ ECC/DDR4 RAM, 57GB+ local VRAM across Dual RTX 3060 24GB & Dual RTX 2080 Ti 22GB NVLink over 10GbE + on-demand 96GB Blackwell G4 burst) pinning orthogonal model families (Qwen3-30B-MoE at 124.2 tok/s, Gemma 4, Hermes 3, snowflake-arctic-embed2) 100% in VRAM alongside PostgreSQL 16 + pgvector HNSW and DBOS queues at 99.9% uptime.
Technical Operations, Management & Applied Systems · Prior Experience
