Projects

A personal AI learning system that keeps the changing world and the user’s demonstrated understanding side by side, then teaches only the difference between them.

• Dual world-state and Mind model
• Rule-based Mind updates, each with a reason
• Agent takeaways checked against sources

TypeScript · React Native · Expo · Hono · Zod · Claude · MongoDB Atlas · Tiger Data · Supabase · Backboard · ElevenLabs · Muse

Working hackathon prototype with a recorded demo. No public deployment.

A production system for YardToonz cartoons. A person picks a moment and clears the rights, then seven worker stages turn it into a validated 9:16 video.

• Separate web and worker processes
• Seven retry-safe stages, database leases
• 77 test files, seven-artifact lineage

Human-directed demo using authorized or deterministic source media. Nothing publishes automatically.

An origination system for home equity investment. Every fact traces back to the page it came from, and deterministic rules decide when a case is ready.

• Framework-independent domain core
• 40 rule and invariant tests
• Contradiction-aware evidence

TypeScript · Next.js · React · Zustand · Zod · Vitest

Independent project on synthetic data. No production deployment.

A fleet-operations simulation service. A LightGBM quantile model forecasts demand, a SimPy discrete-event model runs the night, and an OR-Tools solver assigns vehicles.

• Python FastAPI service, TypeScript frontend
• 25 Pytest tests
• Cross-process reproducibility

Python · FastAPI · SimPy · OR-Tools · LightGBM · TypeScript · Next.js · Pytest

Fictional operator, synthetic demand. Runs locally, not hosted.

A practice system for a Python technical interview. It drills the primitives under each LeetCode problem until they come out automatically, runs real Python in the browser, and scores mastery from what was written, not recognised.

• 689 reps, 91% of planned time spent coding
• Python in the browser, in a Web Worker
• Deterministic, cold-weighted mastery

TypeScript · Next.js · React · Pyodide · CodeMirror · IndexedDB · Supabase · Zod · Playwright

The demo is a short public slice. The full app is a single-user tool.

A Python package and CLI that tests whether next-day crypto direction survives honest evaluation. Saved out-of-sample results stay close to random, and the app reports that.

• Look-ahead leakage audits
• 56 Pytest tests
• Walk-forward, cost-aware backtesting

Python · pandas · NumPy · scikit-learn · LightGBM · SHAP · Typer · Streamlit · Pytest

Research code on public market data, not investment advice. The hosted demo may need a moment to wake.

Five machine-learning algorithms implemented from scratch in TypeScript and drawn on canvas, so each one can be stepped through a single operation at a time.

• Five algorithms implemented directly
• Per-algorithm state machines
• Canvas rendering, dynamic imports

TypeScript · React · Next.js · Canvas

A rebalance-readiness system for separately managed accounts, with effective-dated controls across holdings, lots, restrictions and approvals, ending in an authorised handoff.

• 12 effective-dated controls
• Approvals expire when their basis changes
• Dependency-ordered actions

TypeScript · Next.js · React · Zod · Zustand · Vitest · Playwright

Independent project, synthetic accounts. Never creates or routes an order.
