What I'm looking for

I’m looking for a team where I can build high-performance, scalable frontend systems for AI-native, real-time products—translating complex research into production-ready UX, collaborating cross-functionally, and optimizing reliability and performance end to end.

I’m a Senior Frontend Engineer with 8+ years building AI-powered platforms, real-time systems, and scalable consumer products. I specialize in React.js, TypeScript, Next.js, and modern frontend architecture across AI enterprise platforms, iGaming systems, and NFT marketplaces.

In my recent role, I architected frontend systems for AI-native enterprise platforms for fraud intelligence, claims automation, underwriting risk analysis, and AI-assisted operational decision systems. I developed investigation workflows, AI-powered analytical dashboards, and real-time monitoring systems, including RAG pipelines, semantic search, and vector-based knowledge retrieval to improve document intelligence and operational summaries.

I also build AI agent workflows and explainable AI interfaces—visualizing fraud signals, entity relationships, confidence scoring, and investigation reasoning—while optimizing streaming data workflows and large-scale visualization performance (including ~35% dashboard responsiveness improvements). I’m passionate about high-performance, scalable, user-focused frontend experiences that turn complex AI research into production-ready tools.
