Profile

I define problems, design solutions, challenge the architecture and validate the outcome, while AI handles the implementation. Like a chef running a Michelin-star kitchen.

I founded my first company at 18 and have spent more than two decades building companies, products and technology-driven solutions across hardware, marketplaces and financial services. Today my work focuses on supervised agentic development, orchestration, validation and real-world products.

Independent AI Systems & Product Development

Recent work · Ongoing

Conceive solutions and direct AI coding agents through architecture, implementation choices, validation and delivery. Agents write the code; I remain responsible for direction and outcomes. Most of this work is open source on GitHub.

Elsewhere — The Roads Not Taken

Current research focus

Open research into human–AI decision-making: mapping consequential choices, comparing alternative solution paths, and examining the evidence behind each decision.

Development Cycle

Designed a supervised agent orchestration system with planning, execution, approval gates, validation and recoverable workflows.

Octopus — second-largest contributor

89 merged pull requests to a multi-model AI orchestrator with over 4,000 GitHub stars: agent execution supervision, retry mechanisms, failure recovery and quality gates.
