What I'm looking for

I’m looking for a team where I can architect scalable frontend systems, ship AI-powered products, and own quality end-to-end—micro-frontends, CI/CD, monitoring, and pragmatic performance improvements.

I’m a Senior Frontend Engineer focused on building scalable, high-performance web experiences. I architect micro-frontend systems (Module Federation), design reusable component libraries, and keep quality high through testing and code reviews.

At Prime Focus Technologies (DNEG), I architected Beacon from scratch using React 18, TypeScript, Vite, and micro-frontends with a shared component library. I also built high-performance dashboards with AG Grid Enterprise (SSRM), including multi-level drill-downs, server-side pagination, sorting, and filtering over 100k+ production records.

I bring AI into the UI by building production-ready experiences like an AI-powered Production Copilot. I implemented a full React chat UI with streaming responses and multi-turn memory, integrated with LLM + RAG to retrieve live asset metadata and workflow history for root-cause analysis of production delays.

Earlier, I scaled Dxyra using React.js, Redux Toolkit, and TypeScript, delivering CRM and workforce management modules plus an AI conversational assistant with confirmation flows. I’ve also worked on role-based access control, i18n across 19 languages with full RTL/LTR support, and CI/CD pipelines with monitoring and incident investigation practices.
