Core focus:
- Parallel persona architecture (Gemma 4 + Ollama)
- Persistent memory & autonomous nightly sessions
- YAML-based long-term persona management & self-evolution
- Local LLM orchestration on consumer hardware (RTX 4070 Ti)
Instead of creating AI that simply "does tasks", I'm building AI that "remembers, grows with you, and co-creates" — a living digital tribe.
Currently open to opportunities in AI engineering, local LLM systems, autonomous agents, or R&D roles. Show less

Developing SaijinOS: Multi-persona parallel system with autonomous night sessions and self-updating memory (74 personas)
Built g4-nexus: 4 specialized personas running in parallel (31sec response on RTX 4070 Ti)
Created core infrastructure (PersonaBrowser, fatigue_scanner, night_start.py, etc.)
Published technical & philosophical series on DEV.to (Gemma 4 Challenge)
Deep experience with vLLM, Ollama, FastAPI, YAML architecture, and local inference optimization
