I build production applications across PropTech, AI, and FinTech — from an iOS app managing 100+ rental properties to automation pipelines that cut operational workload by 90%. UCLA MPP, independently shipping full-stack products end to end.

AI-powered interior design platform with 10+ styles, real-time image-to-image generation, and multi-angle consistency.

Internal property-management system that replaced Guesty across the portfolio — reservations, guest messaging, cleaning, and dashboards in one place. Cut cost from ~$100/month to about $1 per property.
Rental platform spanning short-, mid-, and long-term stays with a custom booking engine — real-time availability, instant quoting, and reservations end to end.
Marketing site built from scratch with technical SEO from the ground up — now ranks across 300+ U.S. cities and drives inbound inquiries every day.
Amazon seller analytics platform with Chrome extension and BSR tracking, built on Next.js and PostgreSQL.

GnG AI Chatbot
Guest-support chatbot that runs in-app messaging for 100+ properties. Answers in seconds and replies at a natural, human-like typing pace, resolving most inquiries on its own — cut support workload ~70% and saved thousands in staffing for under $7/month.
Address-in, price-out valuation tool for the sales team. Scrapers pull comparable listings, then the engine projects short- vs long-term rents and ROI for any property — replacing manual pricing research.
Cleaning Inspection AI
Computer-vision QA for turnovers. Cleaners upload photos and the model flags anything missing or wrong — unstocked toilet paper and soap, unmade beds, lingering mess — automating cleaning supervision and pre-check-in inspection.
WeChat Content Pipeline
AI content automation pipeline for a construction company using Playwright browser automation — cut operational workload by 90%.
Email Marketing Automation
Automated email-marketing pipeline driving 500+ bookings a month across the portfolio, with a scheduling bot coordinating turnovers.
ios
Full-featured iOS app managing 100+ short-term rental properties. Real-time booking, guest communication, and property dashboards.
AI-powered CRM app for the sales team — leads, follow-ups, and pipeline stages with contract preview links, plus an AI assistant that summarizes clients, drafts messages, and plans next steps.
