Things I've built that actually matter.
Real problems, real code. Here's a look at the work I'm proud of.
AI-powered grocery intelligence app that pulls real-time pricing and inventory data from marketplaces and convenience stores, then uses ML models to surface deal predictions and personalized shopping recommendations.
✦ The prediction model flagged a flash sale 3 hours before it went live.
A personal OS for life. Track long-term goals, daily habits, and life milestones with visual progress rings and streak tracking — think fitness app, but for everything that matters to you.
✦ The streak system is addictive enough that I've been using it myself every single day.
Comprehensive automated testing suite for an e-commerce platform. Includes UI tests, API tests, and performance benchmarks to catch regressions before they reach users.
✦ The test suite catches 94% of regressions before deployment.
A Python CLI tool that ingests brokerage CSV exports and produces a detailed equity breakdown — sector weights, volatility metrics, Sharpe ratio, and correlation heatmaps — all rendered in the terminal via rich.
✦ Discovered a 0.94 correlation between two holdings I thought were uncorrelated.
A rule-based screener that fetches live market data via yfinance, runs technical indicator filters (RSI, MACD, Bollinger Bands), and outputs a ranked watchlist. Includes a backtesting module to evaluate strategy performance on historical data.
✦ The RSI-oversold filter outperformed a buy-and-hold S&P 500 benchmark by 8% in backtests.
A lightweight Chrome extension that intercepts your ChatGPT / Claude prompt before submission and rewrites it for clarity, specificity, and context — using a local rewrite model or OpenAI under the hood. One click, better outputs.
✦ Early testers reported a 40% reduction in follow-up clarification prompts after using the enhancer.
