I'm a marketer, not an engineer. I shipped open-source AI infrastructure in 3 months by directing AI coding agents.
Short summary
A growth marketer built Myco Brain, an open-source memory layer for AI agents, in 3 months using AI coding agents ($6k spend). The system stores agent memories deterministically in self-hosted Postgres with source attribution, achieving 73.6% QA accuracy. Demonstrates how modern AI agents enable non-engineers to ship production infrastructure.
- •Non-engineer marketer shipped Myco Brain—open-source agent memory layer—in 3 months using AI coding agents
- •Solves agent amnesia with deterministic, source-attributed storage in self-hosted Postgres (vs. black-box memory tools)
- •73.6% QA accuracy on LongMemEval benchmarks; works with Claude Code, Cursor, Windsurf as MCP server; Apache-2.0 licensed
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
