Software engineering student · Backend / Fullstack Developer · AI Character Systems
I build systems where code, behavior logic, memory, perception and long-term interaction meet.
Currently working on M.A.R.I.A. — an author-driven local AI character ecosystem built around a single-user Core runtime, external clients, memory, personality, relationship dynamics and the feeling of presence.
- 🎓 Software engineering student
- 💻 Interested in backend, fullstack, AI systems and automation
- 🛠️ I like building projects that combine code, behavior logic and system architecture
- 🤖 Currently focused on local AI characters, LLM pipelines and character-based runtimes

- ⚙️ I use AI tools as accelerators, but I focus on understanding, reviewing and shaping the architecture myself
An author-driven ecosystem for local AI character systems.
M.A.R.I.A. is my personal long-term AI character ecosystem.
It is not just a chatbot, generic assistant or companion SaaS.
The goal is to build a more realistic local character system with presence, personality, memory, subjective perception and long-term continuity.
The ecosystem is centered around:
Canonical single-user runtime and architectural heart of the ecosystem.
M.A.R.I.A.-Core is built around:
- persona and behavior logic
- memory and context systems
- Maria's perception of user messages
- affection / trust / mood mechanics
- relationship and emotional state dynamics
- opinion and preference evolution
- local LLM integration through Ollama
- FastAPI-based API contracts for external clients
- regression tests for behavior stability
- future external clients such as WebUI, Voice, CV, Avatar / Live2D and Discord integrations
Developer/debug cockpit for observing and testing M.A.R.I.A.-Core runtime behavior.
The Debug WebUI is not the final user-facing Live2D/Unity client.
It demonstrates how the Core runtime can be observed and tested through a lightweight React/Vite interface.
It includes:
- live conversation view
- daily dialogue history
- runtime/debug state panel
- relationship and mood parameter display
- proactive message support
- sprite / Live2D preview experiments
- API integration with M.A.R.I.A.-Core
M.A.R.I.A.-Core focuses on runtime architecture, tests, memory, behavior and AI character systems.
M.A.R.I.A.-WebUI focuses on visual inspection, development tooling and frontend experimentation.
- Building M.A.R.I.A.-Core as a single-user local AI character runtime
- Designing a cleaner Core / external clients architecture
- Improving backend architecture, OOP design and API contracts
- Strengthening tests, regression safety and project structure
- Exploring local LLM pipelines, memory systems and character-based agents
- Turning Maria from a technical prototype into a long-term authored AI character system
