Senior Frontend Engineer
Delivering production-grade web & mobile applications at scale - from Amazon Pharmacy to eBay's PWA. Fluent in React ecosystems, AWS infrastructure, and GDPR-compliant architectures.
Engineering at scale & precision
Hi, I'm Anh Tran - most people call me Tony. I'm a Senior Frontend Engineer (L5) with 10 years of experience delivering production web and mobile applications. I take ownership from initial build through deployment, working directly with business stakeholders.
At Amazon, I led the prescription refill flow for Amazon Pharmacy and owned three React micro-frontends serving 200k+ daily users on Prime benefits pages. Previously at eBay, I maintained the eBayUI Core component library and spearheaded a PWA that cut repeat-visit load time by 40%.
I implement GDPR-aligned frontend solutions, optimise for Web Vitals (CLS/LCP), and integrate AI-powered chat interfaces into production systems. Available for remote roles globally.
The stack I live in
10 years of battle-tested experience across modern web, cloud infrastructure, and mobile platforms.
