Experience

Previously Kozyon / MetaFunnels · Sole developer

• Built a platform used by 1,000+ customers over its lifetime. Customers generated approximately $32M in combined sales through its funnels since 2022, based on platform records and founder reporting
• Built the platform supporting a marketplace-training business with approximately $3.75M in recorded purchase value (USD equivalent), 10,322 purchase records, and 687,104 CRM contact records
• Built and operated OctoFunnel as its sole developer, owning full-stack engineering, UX/UI, technical operations, and partner relationships
• Evolved a PHP/MySQL funnel platform into an AI-oriented TypeScript product combining websites, funnels, CRM, course delivery, messaging, payments, and analytics
• Designed a tenant-scoped virtual filesystem shared by the built-in AI agent, MCP-connected agents, and the visual editor over canonical business data
• Implemented contextual playbooks, server-side validation, revision-aware writes, restorable checkpoints, and durable execution. Tool feedback lets the agent correct ordinary rejected attempts and continue within execution limits
• Built a network of approximately 30 sales partners around a revenue-share model and translated weekly partner discussions and customer feedback into product improvements
