My technical toolkit includes modern technologies like React.js (v19), React Native, Vue.js (v3), TypeScript, Go & Gin, GraphQL, TradingView Advanced Charts, WebSocket, Playwright, TailwindCSS, MUI, PostgreSQL, and Docker. I'm passionate about clean code architecture, performance optimization, automation testing, and creating delightful user experiences.
