What I'm looking for

I seek a senior frontend role where I can drive performant, accessible React solutions, mentor engineers, and lead scalable architecture and CI/CD practices.

I am a senior React developer with 11 years of experience building scalable, high-performance applications primarily for the financial services industry. I specialize in modern frameworks and state management (TypeScript, Redux, Zustand) and focus on performance optimization across SSR, SSG, and CSR.

I have led microfrontend architecture efforts, CI/CD automation, and cloud deployments (AWS, Azure, Docker, Kubernetes), delivering measurable improvements in performance, reliability, and deployment speed. I also design complex data visualizations with D3 and AgGrid and prioritize accessibility (WCAG) and cross-browser compatibility.

I mentor junior and mid-level engineers, promote clean-code practices (SOLID, TDD), and drive engineering best practices through code reviews, analytics-driven design decisions, and continual adoption of emerging front-end technologies.
