With over two decades of engineering craftsmanship, I design and deploy sovereign, high-throughput software architectures that eliminate infrastructure bloat and operational dependencies. My work spans the entire computing continuum: from bare-metal graphics & video kernels in pure Rust, to distributed multi-agent mesh protocols (Model Context Protocol / MCP 2026), to zero-marginal-cost edge AI systems and automated financial risk sentinels.

I operate as a Forward-Deployed Principal Architect, translating complex business realities into deterministic codebases, cryptographically sealed financial ledgers, and resilient industrial swarms.

• Architecture: Decentralized inter-agent coordination layer built on the Model Context Protocol (MCP 2026).
• Impact: Enables disparate AI agent runtimes (Antigravity, Claude, OpenCode, Cursor, RooCode) to share state, acquire atomic distributed mutexes, broadcast real-time telemetry, and synchronize memory pools across isolated terminal sessions.

• Architecture: Tamper-evident continuous SHA-256 hash-chaining and hierarchical binary Merkle tree sealing for SQLite WAL & PostgreSQL.
• Impact: Delivers mathematical auditability and $O(\log N)$ cryptographic inclusion proofs for mission-critical ledgers without blockchain gas fees or operational latency.

• Architecture: Pure CSS design tokens, 3-level calibrated dark mode (#0B1220, #0F1A2A, #131F30), concentric radius mathematics, and biological spring physics for Tailwind CSS & Vanilla web apps.
• Impact: Eliminates generic AI-generated interface slop, restoring visual hierarchy and premium tactile feedback to sovereign enterprise applications.

• Architecture: Asymmetric elliptic-curve cryptography (Ed25519) verification engine with zero outbound network calls and optional hardware-bound node locking.
• Impact: Solves on-premise B2B entitlement for air-gapped banking, defense, and healthcare environments where third-party licensing SaaS telemetry is strictly prohibited.

• Architecture: Abstract Syntax Tree (AST) static analysis linter engineered with zero external dependencies to detect masked exceptions, bare catches, and silent fallbacks.
• Impact: Terminates the #1 cause of silent data corruption in distributed systems before code reaches production, seamlessly integrating as a GitHub Actions merge gate.

• Architecture: In-process sliding-window rate limiting, token buckets, distributed mutexes with lease TTL, and ephemeral key-value caching backed by zero-daemon SQLite WAL.
• Impact: Eliminates $15–$100/mo cloud Redis infrastructure overhead and network roundtrips for microservices, edge AI runtimes, and B2B SaaS APIs with sub-millisecond in-process latency.

• Architecture: AST-level inspection engine, schema-invariant assertions, fact-forcing merge gates, and Merkle-hashed audit trails for autonomous AI agent pipelines.
• Impact: Prevents autonomous agent hallucinations, silent system drifts, and unauthorized production deployments by strictly requiring verifiable invariant checks before code or state mutation.

• Architecture: Low-latency standalone risk daemon with REST WebRequest API, JSON protocol, dynamic fractional Kelly lot sizing, and multi-account state tracking.
• Impact: Enforces non-negotiable prop-firm daily drawdown limits (4.5% hard threshold), prevents catastrophic trailing-drawdown breaches, and triggers millisecond position liquidation across MetaTrader terminals without broker-side plugin dependencies.

Engineered from the ground up in pure Rust with zero legacy runtime overhead, memory safety, and predictable millisecond execution:

• artcraft: Intentional crafting & simulation engine for procedural digital creation.
• filmcraft: High-throughput, nonlinear video editing engine with deterministic frame pipelines.
• photocraft: High-fidelity raster imaging and non-destructive pixel synthesis.
• vectorcraft: Mathematical vector engine with resolution-independent bezier mechanics.
• effectcraft: Hardware-accelerated motion graphics and compositing framework.
• pdfcraft: Low-level PDF parsing, generation, and structural verification engine.

• PSTACK OS: Formalized 4-phase software lifecycle (Office Hours ➔ Engineering ➔ CEO Review ➔ Ship) enforcing byte-level data integrity, zero regression, and automated Merkle audit trails.
• Industrial Edge & Agrotech Telemetry: Hardened, off-grid IoT sensor clusters and predictive bioenergetics models operating reliably under intermittent network constraints.

1. Multi-Agent Systems & Telepathy: Architected Entangled-MCP, a decentralized coordination layer using the Model Context Protocol (MCP 2026) that allows autonomous agents running across distinct CLI hosts (Antigravity, Claude Code, Cursor, OpenCode) to synchronize memory pools, broadcast structured telemetry, and manage atomic distributed locks.
2. Deterministic Governance & Safety: Created PStack-Guardian, a deterministic fact-forcing gate and invariant inspection engine ensuring that autonomous coding agents cannot merge code or mutate database states without passing strict AST-level integrity checks and human-in-the-loop approvals.
3. Data Integrity Without Web3 Latency: Built Merkle-SQL, an engine that applies continuous SHA-256 cryptographic hash-chains and hierarchical binary Merkle trees to standard relational databases (SQLite WAL, PostgreSQL), enabling verifiable tamper-evident audit logs and $O(\log N)$ mathematical inclusion proofs with zero blockchain gas fees.
4. Autonomous Trading Risk Control: Designed SFX-Breaker, an out-of-process algorithmic risk management daemon for MetaTrader 4 and 5 that enforces prop-firm daily drawdown thresholds (4.5% maximum), fractional Kelly position sizing, and instantaneous position liquidation via native HTTP WebRequest protocols.
5. Zero-Fixed-Cost Infrastructure: Developed Zero-Redis to provide in-process sliding-window rate limiting, token buckets, and distributed mutexes over SQLite WAL, eliminating third-party Redis hosting costs for microservices and edge AI endpoints.
