## About

I’m a software engineer with 10\+ years of experience, with a strong foundation in frontend engineering and a career that has increasingly evolved toward architecture, platform engineering, and technical leadership\. I enjoy solving problems that go beyond a single feature—understanding the underlying challenges, simplifying complexity, and building reusable systems that help teams move faster\. Over the years, I’ve worked across enterprise products, new\-business initiatives, and large\-scale platforms, including AI\-powered experiences at Microsoft, a real\-time drone monitoring platform at Rakuten, and reusable editor infrastructure at Picsart\. I remain hands\-on with technology while taking broader ownership of architecture, technical direction, and engineering practices\. Areas I enjoy working in: • Frontend & UI Architecture • Platform Engineering & Developer Experience • AI\-powered Applications & Developer Productivity • Scalable Web Applications • Performance, Reliability & Observability • Technical Leadership & Mentoring
