John Evans

I am a seasoned Senior Frontend Engineer with over 10 years of experience in building scalable, high-performance web and mobile applications at leading tech companies such as Pinterest, Instagram, and Facebook. My expertise lies in React, TypeScript, and design systems, complemented by a strong backend knowledge in Python, Go, and Node.js. I have a proven track record in cloud-native development, CI/CD optimization, and real-time performance monitoring, which has enabled me to deliver exceptional user experiences.

At Pinterest, I led a significant migration project that improved type safety and reduced onboarding time for new engineers. I drove the adoption of the Gestalt design system and implemented performance enhancements that reduced homepage load time by 35%. My commitment to accessibility and inclusive design has resulted in a shared React library that adheres to WCAG standards, ensuring a better experience for all users. I thrive in cross-functional environments, negotiating trade-offs between performance and design fidelity to achieve balanced solutions.

Previously, at Instagram, I co-architected Instagram Reels and launched features that drove millions of daily engagements. My experience at Facebook involved optimizing algorithms and developing internal tools that significantly reduced deployment times. I am passionate about mentoring junior engineers and fostering a culture of engineering excellence, making me a valuable asset to any team.
