Built a real-time fraud detection engine at Meridian FinTech (Python, Scikit-learn, Kafka) that reduced fraudulent transactions by 43%, saving $1.2M in year one. Also led a zero-downtime migration of core banking APIs to AWS Lambda + API Gateway, cutting server costs by 55% and p99 latency from 820ms to 94ms. #FinTech #Python #AWS #MachineLearning

I created a Solana-focused crypto wallet app designed to make managing digital assets feel clearer, calmer, and more premium. The app lets users track their portfolio, view live market prices, swap tokens via Jupiter, and send or receive assets, with real-time data powered by Alchemy, CoinMarketCap, and Helius.

A big part of my process was using @mobbin for inspiration and UI research. I studied premium fintech patterns, interaction flows, and visual hierarchy, then translated those ideas into a product that feels polished, intuitive, and trustworthy.

Building it with @Anything made the process much faster and smoother, and the final result is fully responsive. Really enjoyed this one 💛 Project: https://crypto-wealth-management-ap-502.created.app

For the #levelupwithbubble challenge, I built HashHouse...think LinkedIn meets Kaggle, but for blockchain security professionals. It's a platform where security researchers publish vulnerability reports, build a public reputation on the leaderboard, access a curated resource library, and use our API to train AI security models on real-world data.

The blockchain security space is less than 5 years old but already has 60,000+ researchers, 300+ firms, and interest from top AI labs like Anthropic and OpenAI. It's projected to be a $5B+ industry by 2034. HashHouse is built to be the home this fast-growing community has been missing. Went from idea to live product in 4 days, entirely on Bubble.
