What I'm looking for

I’m looking for senior frontend roles where I can improve user experience and business metrics through performant architectures, reusable UI systems, and collaborative product development.

I am a senior frontend engineer with extensive experience building and maintaining large-scale media and client-facing web applications. I specialize in performance optimization, reusable component design, and implementing features that improve user experience and revenue.

Across product, contract, freelance, and internship roles I have led frontend work for major media sites and enterprise clients, implementing solutions like infinite scroll, multi-role authentication, Elastic Search, Google Maps integration, and payment gateway integrations.

I emphasize Core Web Vitals, automated unit testing, and modern frontend tooling — React/Next.js, TypeScript/ES6, testing with Jest/Cypress/RTL, and design-token-driven UI implementations. I maintain and upgrade libraries and architectures to ensure stability and scalability.

I hold a Computer Science degree (cum laude) and bring a collaborative, pragmatic approach to engineering: delivering measurable UX and business improvements while keeping code maintainable and performant.
