Building modular knowledge systems, developer tooling, and creative automation.

I'm a systems thinker and builder that turn fragmented, real-world information into structured, reliable workflows which focus on metadata-driven automation, local-first tooling, and structured knowledge systems. My work bridges my background in healthcare, research, and development. Each project lets me handle messy data, design robust pipelines, and ship usable tools that reflect iterative learning, reproducible workflows, and a commitment to open documentation.

Interests & Background

Healthcare × Data Interoperability Years of building registry studies, harmonization frameworks, and clinical research pipelines at major ophthalmology centers. Deeply invested in standardized, high-quality datasets that improve patient outcomes.

Developer Tooling, KMS and Libraries Obsidian plugin development, vault architectures, and metadata-driven automation. Obsessed with reproducible workflows, schema-first design, and local-first infrastructure.

Creative Systems Blockchain tutorials, worldbuilding vaults, and experimental prototypes. I blend academic rigor with playful experimentation—documenting everything for portable, auditable knowledge.

My Work

I design and ship local-first, modular systems that connect research, personal knowledge, and developer workflows. The core problems I am trying to fix are fragmented information across tools, repetitive manual processes, and low-trust pipelines that are hard to reproduce or audit. My projects focus on turning scattered notes and datasets into structured, interoperable, and automation-ready systems that reduce friction, improve clarity, and make collaboration easier.

High Value Projects

vault-library-pipeline solves cross-tool fragmentation by standardizing research intake from Zotero into Obsidian using strict naming conventions and YAML frontmatter. This turns scattered references, notes, and metadata into one structured and interoperable knowledge flow.
Awesome-Test-Vault reduces repetitive manual organization by providing a reusable vault architecture with predictable structures, templates, and automation patterns. The result is faster setup, lower maintenance overhead, and clearer long-term knowledge operations.
cpp addresses low-trust and hard-to-audit learning pipelines through transparent, step-by-step examples and documented progression. By making the learning path explicit and reproducible, it becomes easier to verify assumptions, review decisions, and iterate confidently.

Academic & Clinical Profile

With multidisciplinary experience in research coordination, digital health, and user-centered product design, I build systems that turn fragmented, real-world information into structured, reliable workflows. My background in healthcare, research, and development lets me handle messy data, design robust pipelines, and ship usable tools.

Founding Principles of my Work

Prefer offline-capable, self-owned data stores.
Model before UI; schemas drive automation.
Composition: isolate concerns into pluggable units.
Log decisions, schema shifts, structural refactors.
Layering: build thin vertical slice → refine → generalize.
Then abstract: code/prototype before theory summaries.
Apply concepts from systems design, worldbuilding, and data modeling back into personal knowledge tools.
Translate tacit shortcuts into explicit documented standards.
Open-source collaboration: I believe knowledge and tools grow stronger when shared. My approach is rooted in transparency, mentorship, and building together through documentation, code, or community support.
