What I'm looking for

I seek a role where I can build scalable web applications, improve UX and performance, work on accessible, data-driven products, and grow into broader system design or engineering leadership.

I am a results-driven full-stack developer with strong expertise in React, Next.js and Node.js, having led front-end initiatives and engineered microservices that improved delivery efficiency and user engagement across large-scale campaigns.

I build responsive, accessible web applications and dashboards, optimize performance and developer workflows, and deliver measurable product improvements—reducing debugging time, improving page views, and increasing accessibility and delivery metrics.
