What I'm looking for

I seek senior frontend roles focused on building modular, performant React/TypeScript UIs, integrating AI features, mentoring teams, and collaborating cross-functionally in product-driven environments.

I am a Senior Frontend Engineer with over a decade of experience building fast, intuitive, and scalable web applications across fintech, healthcare, and SaaS domains.

I specialize in React, Next.js, Angular, and TypeScript, and I design modular component systems, optimize rendering performance, and integrate complex REST and GraphQL APIs into predictable user experiences.

I have led frontend efforts at large organizations, created shared UI component libraries, and integrated AI-enhanced features like LLM-powered suggestions and ML-driven UI insights to improve user efficiency.

I mentor engineers, champion accessibility and testing, and drive modern frontend practices to deliver polished, resilient interfaces that align product, UX, and backend teams.
