I build the systems behind financial products.For the past 7 years, I've worked across Fintech payments, banking, Trading, AI and Web3 Crypto, from the dense User Interface to distributed backends, real-time data pipelines, and infrastructure in React, TypeScript, Node, Java, Go, and Rust.
software where mistakes have consequences, 
real-time systems that 
trade, settle, and move money. 
React, Next.js, and React Native for interfaces that update every second and can't drop a frame. Trading terminals for CEX and DeFi venues, non-custodial wallets, and financial dashboards that stream order books, liquidation heatmaps, and portfolio PnL over WebSockets. When off-the-shelf charting can't keep up, I go down to the rendering layer itself: custom candlestick series and Canvas bitmap coordinate systems built on top of libraries like TradingView's Lightweight Charts.
