Backend developer who builds side projects to answer real questions.
I believe benchmarks beat opinions, simplicity beats cleverness, and pain beats doctrine.
- Turning my Obsidian vault into an ontology — the same 6,452 notes modelled twice, as a SQLite property graph and then as RDF/OWL, to find out where a knowledge graph stops and an ontology starts (vault-ontology)
- Evolving my TDD workflow — combining design trade-off analysis, 46 object-design rules, and pattern-based refactoring signals (validated end-to-end in Checkout Engine)
- Turning technical books into operational rule sets I can apply during code review (Object Design Style Guide: 46 rules, SQL Cookbook: 28 rules)
- Managing 6,000+ notes in Obsidian with a custom knowledge promotion pipeline — dev knowledge (Backend, DevOps, DB, AI) at the core, surrounded by book reviews, video logs, a Mind Compiler for refining raw thoughts, and a Logic Forge for sharpening arguments
| Project | What & Why | Stack |
|---|---|---|
| vault-ontology (in progress) | Rebuilding a working tool from a blank file, with the original pinned beside it as an answer key I don't open until I'm stuck. Then the same 6,452 notes, modelled a second time as RDF/OWL. Part 1 done: 162 tests, zero dependencies. | Python, SQLite, rdflib, SPARQL, pytest |
| voxprep | The whole GPT-SoVITS lifecycle behind one CLI — slice → asr → review → train → infer — including the interactive review step upstream never had. Preprocessing rebuilt TDD-first, ML stages ported in. | Python, Typer, Rich, pytest, uv |
| Checkout Engine | A 9-phase TDD evolution where design patterns arrive only when Forces require them. Methodology validation over 3 days, not a product. | Python, FastAPI, pytest |
| Backend Benchmark Lab | 5 frameworks, 26 scenarios, 10-run averages. Same logic, different implementations. | FastAPI, Django, Express, Rails, k6, Docker, Prometheus |
| Household Ledger | Personal finance app. Migrated from React + FastAPI + PostgreSQL to a single Rails 8 monolith. Zero external dependencies. | Rails 8, SQLite, Hotwire, Terraform, Proxmox |
| Redis Pattern Lab | 12 production-grade Redis patterns, benchmarked against SQLite. | FastAPI, Redis, Docker |
