Private venture studio. Architected and leading development of Nexus, a multi-tenant financial wellness platform (Next.js/TypeScript/PostgreSQL) with secure Python/FastAPI backends. Built the SPARC framework (3,000+ lines, 12 agents, cutting scaffolding time from 2 days to 4 hours). Shipped Zetto (sub-second Japanese voice AI, 75% cheaper than Gemini Live). Self-funded via retail operations — zero VC, 100% IP ownership.

Architected and executed advanced benchmarking environments to test autonomous coding agents. Designed multi-layered software vulnerabilities, state-sabotage vectors in containerised sandboxes (e.g. Rust/Axum), and audited complex asynchronous codebases to validate agent reasoning. Built strict Docker footprints with defensive blanket-deny patterns and immutable dependency trees to guarantee total runtime isolation.

Evaluated and refactored AI-generated code across Python, JavaScript, and other languages to enforce correctness and design best practices. Developed targeted coding challenges, unit tests, and runtime environment validations to stress-test LLM reasoning capabilities.

Architected and built the 'Magnet AI Agents' platform, deploying bespoke voice and chat agents that automated client intake and lead qualification. Led development of 'Magnet CRM'—a white-label sales OS deployed in under 7 days. Engineered and implemented the SPARC development workflow, cutting build times by 75% across the team.

Directed end-to-end operations for high-volume retail units. Managed cross-functional teams to maintain inventory integrity, cost controls, and tight-margin targets under intense operational pressure. Self-funded Axion R&D — every operational bottleneck is a bug.

Defended 99.9% uptime across 100+ high-volume POS sites. Conducted monthly OTP Tech Travel Path audits, troubleshooting network latency and hardware/software faults under heavy Friday night rush pressure. Last shift: field-audited and filed an Auror report on a $599 manual system ORC exploit.

Managed store P&L, logistics, and team performance under intense margin pressure. Automated labour allocation and shift scheduling. Designed operational SOPs that scaled headcount without management bloat. Every dollar of margin funded early Axion R&D.

Modular Dockerized middleware platform for distributed community ops. Ripped out file-based loading, wired in manifest-driven GitHub sync. 46 stars, zero promotion. Contributors extended it without touching core.

Managed daily operations for the brand's busiest national location. Directed recruitment, onboarding, and training of 70+ crew members for two new restaurant launches. Implemented tight inventory control loops that slashed food waste by 15%.

Shipped early OSS contributions and built the visual language that became the Axion design system. Learned to code by breaking things that actually mattered. Foundation for everything since.
