Projects
Working builds, each one self-contained. The flagship projects carry their own README.
Trading Simulator / PnL Tracker
A shared public trade book. Open a simulated stock or option position and watch the PnL move against live market data.
Company Scorer
Scores a company on valuation, leverage, growth and profitability from SEC EDGAR filings and market data, then backtests whether the score predicted anything.
Pipeline World
Submit a character and watch it move through a real queued pipeline (validate, test, build, deploy) in a top-down world. Every run is logged and queryable on the analytics page.
SRE Infra Layer
The Redis queue, cache-aside world state, and per-IP rate limiting that Pipeline World runs on, with a live dashboard.
Site Traffic Analytics
An analytics board over this app's own network traffic: request volume over time, latency percentiles, error rate, and the busiest endpoints and outbound calls. Not visitor browsing, for reasons covered on the page.
Timed-Squares
A turn-based survival game on a 10x10 grid, playable right in the browser. Dodge obstacles that telegraph their next move before they make it, and outlast an escalating spawn rate. Public leaderboard, no login.
Tiny JVM
A compact stack-based virtual machine written in C that runs the same bytecode in the browser (WebAssembly) and, eventually, on a microcontroller. Programs are written in a small custom language and compiled to that bytecode by a real Java toolchain (lexer, parser, code generator). Try it live: step through a recursive factorial, or watch an over-temp-alarm program read a simulated sensor and drive a simulated GPIO pin.
Market Data Warehouse
yfinance's full price/dividend/split history pulled through an idempotent ingestion job into a dbt dimensional warehouse: a fact-table family (price, technical indicators, risk metrics) sharing conformed dimensions, plus a clearly labeled (not financial advice) trend projection. This page queries the built warehouse live, with a timeframe picker. Same dbt code runs on DuckDB, MotherDuck's free tier, or Snowflake.
Top Interview 150 Tracker
A personal interview-prep dashboard over LeetCode's official Top Interview 150. Pick a problem, run the 20-minute timer, compare to the solution, then mark it Yes or No. Progress is saved in the browser, no login.
AI Assistant
A retrieval-grounded agent, not a scripted chatbot: a LangGraph agent loop decides for itself which tools to call and in what order, pulling real data from this site's own live projects (trading simulator, pipeline world, company scorer, timed-squares) instead of describing them from memory. Its flagship example chains three tool calls on its own -- a stock quote, a trend projection, then a written risk report -- deciding at each step what to call next based on what the last one returned. Retrieval runs over a pgvector store with local embeddings; generation is Groq, behind a rate-limited, prompt-injection-aware public endpoint. A stats page tracks tone, volume, and top questions from the logs, with no model calls.
