UW ECE grad student with 5+ years of backend automation experience, now building full-stack and AI-powered applications across Python, JavaScript, and cloud platforms.
Seeking 2026 SWE internships.
Hi, I'm Yulo — a full-stack developer and former backend automation engineer with 5+ years of experience building high-reliability data pipelines in the global clinical research industry. At Parexel, I engineered large-scale ETL workflows and designed automated data-processing frameworks, improving execution speed, system reliability, and cross-team delivery efficiency.
Today, I build full-stack and AI-powered applications using Python, JavaScript/TypeScript, SQL, and modern cloud platforms such as AWS and Cloudflare Workers. My recent work includes serverless AI agents, Excel automation systems, and Chrome extensions designed for productivity-focused users.
I’m pursuing an M.S. in Electrical and Computer Engineering at the University of Washington, specializing in software engineering, data systems, and AI-driven applications. I’m passionate about building practical tools that help people work faster, think clearer, and solve real-world problems.
