Metadata-driven systems for PKM, healthcare data, and creative automation.
Systems thinker focused on local-first tooling, schema-led automation, and reproducible creative research pipelines.
- Role: Administration agent in ophthalmology + builder of modular knowledge infrastructures.
- Angles: Local-first automation, metadata modeling, reproducible vault tooling, clinical research operations.
- Now: Formalizing informatics foundations while shipping Obsidian tooling, healthcare ops trackers, and creative DJ workflows.
- Reach: Fastest via LinkedIn or GitHub issues; async collaboration preferred.
- Creative systems outside curriculum → autonomy + curiosity.
- Autodidact sprints in scripting, schema design, automation.
- Healthcare data coordination → obsession with interoperability.
- Current: blend formal CS study with production-ready vault, clinic, and creative tooling.
Applied daily; kept intentionally lean for local-first deployments.
Core Languages & Data
- TypeScript (Obsidian/VaultOS, local-first services)
- Python (automation, data pipelines, AI adapters)
- Rust + C++ (systems probes, performance experiments)
- SQL/SQLite, Markdown, YAML frontmatter schemas
Services & Runtime
- FastAPI, Node.js microservices, Docker for isolation
- Planned WebSocket layer for live DJ session sync
- GitHub Actions roadmap for schema validation + lint gates
Experience & Creative
- React/Figma/Tauri for local desktop surfaces
- Adobe Suite + GIMP/Canva for assets
- Unity + custom engines for experiential prototypes
PKM, Automation & AI
- Obsidian + custom plugins (VaultOS ecosystem)
- Template-driven vault ops, metadata QA, semantic tagging
- ChatGPT, Microsoft Copilot, Ollama for multimodal ideation + tagging
Compact, high-signal lists. Each table is collapsible; most repos are MIT unless noted.

Looking for a repo not listed? Everything lives under github.com/PtiCalin with tags in descriptions.
Always open to co-design metadata standards, local-first tooling, and clinical research automations. Ping me with:
- Problem framing, existing schema snapshots, or ops pain points.
- Desired fidelity (prototype vs. production) and collaboration cadence.
- Constraints around privacy, offline-first requirements, or creative direction.
Async deep dives are welcome; I document everything for portability.
🌱 Iterate with curiosity. Formalize with care.
