Industry Experience

Software & Internet
    paper Real-Time Meme Coin Alert Bot

    Built a real-time Solana token monitoring bot that polls DexScreener every 5 minutes, scores tokens using a composite formula (volume 40%, liquidity 40%, rug risk 20%), and surfaces high-signal alerts via a live web dashboard. Surfaces emerging tokens within 5 minutes of meeting signal thresholds — hours before they appear on mainstream trackers. Includes a velocity gate to filter noise, SQLite dedup with 24-hour window, RugCheck API integration for safety badges, and a FastAPI backend with APScheduler. 67 automated tests (unit + integration against live APIs).

    paper AI-Powered Pet Relocation Checklist Platform

    Built the backend and AI data pipeline for a pet relocation platform covering international travel regulations. Reduced research from 5+ hours across government sites to a guided 10-minute checklist. Dual-LLM pipeline (Claude + Gemini) runs in parallel, consolidates outputs with Jaccard similarity matching, and flags conflicts for admin review. Admin UI for managing live routes, step timing, and community uploads. Deployed on Vercel + Supabase with CI/CD and Sentry error tracking.

    paper AI-Powered Community Game Finder

    Built a real-time game discovery platform that monitors community messaging groups for game announcements. Reduced time to find a local game from 20+ minutes of manual group searching to under 60 seconds. A 3-stage LLM pipeline (regex → template → Gemini batch) parses unstructured messages and extracts structured game data — location, time, skill level. Results are served via a REST API to a web UI with browse and AI chat modes. Includes a Telegram digest bot for daily game summaries. Deployed on GCP with CI/CD, auto-rollback, monitoring alerts, and 285 automated tests.
