At Tradler, I led the migration of a multi-tenant B2B SaaS platform from a legacy Laravel monolith to a React 18, TypeScript and Vite single-page application. I also shipped its integrated mobile application with Capacitor and Ionic.

I established the new codebase's engineering standards, state architecture and automated delivery pipelines. I developed gamification modules, manager analytics dashboards and multi-role permission settings.

At Devinnotech, I built real-time frontends for competitive esports applications using React, TypeScript and WebSockets. Earlier, I co-built an internal UI kit at NWS LAB and developed REST API-integrated frontend applications at Elastic Systems.
