Senior Software Engineer with 9+ years of experience building scalable web and mobile applications, specializing in frontend architecture with strong full-stack and AI integration skills. I work with modern frameworks like React, React Native, Next.js, and Vue.js on the frontend, and Node.js (NestJS), Python, and Java Spring Boot on the backend. I've delivered high-impact products across the US, Korea, and the Philippines, owning core features end-to-endfrom translating Figma designs into accessible, production-ready interfaces to building secure REST APIs and payment systems (Stripe). I also integrate AI-powered features using LLMs (OpenAI pipelines) and CNN-based image processing, and use tools like Claude Code daily to accelerate development. I'm comfortable in remote, cross-cultural teams and enjoy mentoring junior developers, leading UI architecture, and solving complex production challenges. Let's build something great together!
