Wealth Path

Managing personal finances is tedious when transactions need manual categorization and there's no easy way to ask plain-English questions about your spending. Wealth Path automates categorization with AI and lets users query their financial data conversationally.

Role: Solo developer (full-stack) — the hardest challenge was designing a Supabase PostgreSQL schema with deduplication logic to ensure clean transaction data across repeated imports, while keeping LLM query latency acceptable.

Shipped a working finance app with AI-powered transaction categorization and an LLM chat interface for natural language questions about spending habits and financial goals.

🏆 1st Place

Digital Transformation AI Hackathon

City clerks spend hours manually searching disparate document systems to fulfill public records requests. This AI-powered search tool ingests, vectorizes, and semantically queries thousands of public records — reducing retrieval from minutes to seconds.

Role: Cybersecurity Team Lead — designed the security posture of the application and audited the full stack for vulnerabilities. The hardest challenge was locking down the vector search pipeline against SQL injection and side-channel attacks while keeping query latency under 2 seconds under hackathon time pressure.

Won 1st place out of all competing teams; the tool demonstrated a complete data pipeline from S3 ingestion through Bedrock vectorization to OpenSearch semantic retrieval.

Arbitrage Betting Software

Sports bettors have no fast way to identify guaranteed-profit arbitrage opportunities across multiple sportsbooks in real time. This tool scrapes live odds and surfaces bets where the combined implied probabilities across books fall below 100%.

Role: Solo developer — the hardest challenge was normalizing inconsistent odds formats (American, decimal, fractional) across sportsbooks and handling rate limiting without getting IP-blocked during repeated polling.

Automated detection of arbitrage opportunities across 5+ sportsbooks, surfacing bets with 2–8% guaranteed return when opportunities are present.

Mile High Matches

Airports are high-stress, impersonal environments — there's no easy way to meet other travelers with shared routes or interests. Mile High Matches is a cross-platform dating app built specifically for airport connections.

Role: Team developer — the hardest challenge was designing real-time match logic that correctly fired Firebase Auth flows and Firestore listeners without race conditions when two users mutually matched.

Shipped a cross-platform mobile app with user authentication, profile creation, and real-time match notifications on both iOS and Android via Flutter.

Personal Portfolio

A fast, zero-dependency personal site that showcases projects and work history without relying on heavy frameworks or a build pipeline — deployable instantly via GitHub Pages.

Role: Designer and developer — the core challenge was achieving a clean, responsive layout and modern design system from scratch without a component library or CSS framework.

Live site deployed on GitHub Pages, serving as the canonical home for work history, projects, and contact information.
