Nearly a decade of full-stack engineering — and a rare range that runs the entire vertical. I ship complete products from zero, solo or leading from the core: AI infrastructure, end-to-end Web3, high-frequency trading systems, and low-level security & embedded research. React, Vue, Next.js, Go, Rust, Solidity, kernel C — whatever the problem needs, I write it.

As the initiator of NyphexAI, I'm building a post-quantum, decentralized AI training network — and on top of it ACGN Studio (AI creative suite) and the Creative SDK (AI Agent toolkit) for multi-model orchestration, prompt-engineering optimization, and autonomous agent deployment. I designed and shipped Gemina — a full AI-avatar product with its own on-chain economy — solo, concept to launch, in 10 days.

• 🚀 Shipped a full AI-avatar + on-chain economy product solo in 10 days — design, frontend, backend, and smart contracts
• 🧠 Initiator of NyphexAI, a post-quantum, decentralized AI training network, and the acgnX Model
• ⛓️ Frontend / full-stack lead across 15+ Web3 projects — DEXs, NFT platforms, DeFi wallets, and AI SocialFi
• 📈 Built a Golang matching engine sustaining 100k+ orders/sec at P99 < 1ms, plus live market-maker & arbitrage bots
• 🔒 Independent iOS / macOS vulnerability research with coordinated disclosure (Apple Security Bounty)
• 🧰 Equally at home from kernel & firmware up to UI — OpenWrt, KVM/vGPU, embedded Linux, React

Full-stack Developer & Quant Engineer — the low-latency, money-on-the-line core of centralized (CEX) and decentralized (DEX) exchanges.

• Matching Engine — high-concurrency order matching in Golang using Price-Time Priority and a lock-free ring buffer, handling hundreds of thousands of orders/sec at P99 latency < 1ms.
• Market Maker Bot — multi-exchange MM bot based on the Avellaneda-Stoikov model for dynamic bid/ask spread adjustment; real-time order-book depth over WebSocket with automated placement/cancellation and inventory risk control.
• Arbitrage — cross-exchange triangular and statistical arbitrage via a CCXT unified interface, with millisecond spread monitoring, automated execution, and slippage protection.
• Risk Control — real-time risk engine on Redis Streams; anomaly detection (whale orders, wash trading), position-limit monitoring, and automatic circuit breakers.
• Data Pipeline — Kafka + ClickHouse trading data warehouse with real-time candlestick aggregation, volume analytics, and user-behavior analysis; Grafana + Prometheus dashboards.

Independent security research, close to the metal and with a focus on responsible, coordinated disclosure.

• iOS / macOS vulnerability research — minimal-reproducible vulnerability reports for coordinated disclosure (Apple Security Bounty).
• Virtualization security — hypervisor / KVM guest-to-host escape research.
• Embedded Linux system security — firmware, bootloader, and secure-boot analysis on routers, ONT/modems, and other embedded devices.
• Mobile system security — bootloader bypass and jailbreak research.
• Tooling — exploit development and automated vulnerability-analysis frameworks.

Low-level engineering across firmware, networking hardware, and virtualization — the layer most developers never touch.

• Custom firmware — OpenWrt builds and firmware for ONT / XGS-PON optical modems, routers, and LTE/5G CPEs.
• Virtualization — KVM / Proxmox GPU passthrough & vGPU unlocking; macOS on non-Apple hardware (Hackintosh).
• Disaster tech — Japan Earthquake Early Warning (EEW) tooling and JJY radio time-signal emulation on Raspberry Pi.
