At iRage Broking Services, I developed a retail trading mobile application from scratch in Flutter, with real-time data synchronization and multiple concurrent WebSocket connections. I also built custom trading charts with one-click trading, reducing execution time by 40%.

I built a desktop trading application in Tauri, Rust, and React for futures and options traders. The role also involved designing core trading screens, integrating APIs, and adding secure authentication and push notifications.

At Trinkerr, I developed SEO-focused Vue.js pages that reached Top 2–4 Google search rankings and built a JavaScript SDK with 100% Jest test coverage. Earlier, I contributed to React Native applications at Hybrowlabs Technologies and Fitmedik, including native features, API integrations, and app performance improvements.
