AI Voice Assistant

A fully hands-free desktop AI assistant powered by Google Gemini, with an async Python core, a real-time PyQt6 heads-up display, and natural speech input and output.

  • Automates multi-step workflows through 20+ pluggable skill modules: desktop control, computer vision, browser automation, coding, and media.
  • A persistent memory store personalizes responses over time.

Engineering noteRuns the asyncio Gemini session on a background thread and updates the PyQt6 UI through Qt signals. It reconnects automatically with exponential backoff, capped at 30 seconds.

Trade Journal

AI Trading Analytics SaaS

A subscription trading-analytics SaaS with a 9-table PostgreSQL schema (Prisma), 16 REST endpoints, Stripe billing, and NextAuth authentication.

  • A built-in AI review (Gemini and Groq) evaluates win rate, P&L, and recurring mistakes, and returns personalized, actionable feedback so traders improve week over week.

Engineering noteThe weekly AI review budgets tokens per request to stay inside Groq's per-minute limit, and tells the user exactly when to retry instead of failing silently.

Stock Analyzer

Quantitative Equity Screener

A Python screener that ranks stocks and ETFs by blending fundamentals (P/E, ROE, debt/equity, growth) and technicals (RSI, MACD, 200-day MA) into a weighted score, using live yfinance data.

  • A position-sizing and dollar-cost-averaging engine spreads a fixed budget across up to 8 holdings within configurable risk limits.

Engineering noteScores are weighted 60% fundamentals and 40% technicals, and every threshold lives in a YAML config. Market data is cached on disk, so repeat scans are instant.
