Message

At Huawei Technologies, I built the internal device-management dashboard used by operators across 12 regional offices and created a shared library of 40+ UI components adopted across four applications. I also designed frontend state architecture and established testing practices that reduced post-release regression bugs.

As a freelance Senior Software Engineer, I architect API design for a real-time financial analytics platform, replacing multi-second polling with sub-second updates. I build React and Next.js applications and full-stack services, with work spanning GraphQL APIs, performance improvements, automated testing, and headless Shopify storefronts.
