makerOS
Emerged during the development of Elyvite from the realisation that pure vibe coding is not enough for demanding products: a structured way of working for AI-assisted software development became necessary.
- Co-development of a structured environment in which specialised AI agents collaborate like an agentic scrum team
- Shared project memory, handoffs and explicit quality gates to keep work aligned with the business context
- Local AI via Ollama and role-based model routing
- Workflows for product planning (whiteboard and kanban), UX, architecture, implementation, review, testing, security and documentation
- Connecting several coding CLIs and AI providers through MCP-based tooling
- Contribution to the Flutter/Dart desktop application and embedded workflow and MCP services
Stack: Flutter, Dart, MCP, SQLite, FTSS, Ollama, Cloudflare, Multi-Agent Orchestration
