📄️ German Spelling Alphabet
A simple German spelling alphabet app evolves into computational linguistics research -- implementing the ALINE algorithm, running simulated annealing over 61K words, and producing a mini research paper in two sessions.
📄️ Cal-FOSS: OpenCal
Liberating a 470,000-line scheduling platform from proprietary code -- directing an AI team through a codebase I never read, then pivoting mid-surgery to a plugin architecture.
📄️ Home Infrastructure: A Family Operating System
Building a unified home platform across three workspaces, four languages, and twenty self-hosted services: spec-driven autonomy, air-gapped relays, and the luxury of making something just because you want it.
📄️ Mermaid.js Team Topologies
Adding a new diagram type to a 14 000-commit open source project: a layout engine that grew to 3 000 lines, 2 153 tests, and the cybernetic feedback loops that made it converge.
📄️ Orbital AI Datacenters
A rigorous physics and economics analysis of orbital AI datacenters with 3D visualizations, fact-checked across 13 parallel searches, then pivoted into a satirical incremental game where every ending is bad.
📄️ Promotion Simulator
When a colleague's promotion question had too many interacting variables for a formula, the only honest answer was Monte Carlo -- 10,000 simulated teams with skill matrices, coaching strategies, and bimodal attrition, built across 3 sessions of pure planning-then-execution.
📄️ Rental Property Investment
How domain expertise in business operations, consulting frameworks, and rental property economics transformed a pasted spreadsheet into an interactive bilingual analytical engine with sensitivity analysis -- across 6 sessions and 216 prompts.
