I'm a Product Engineer based in Helsinki with a background that spans both sides of the product-engineering divide. Before writing code professionally, I spent five years in product management for EdTech platforms in Taiwan, including a K-12 learning product used by over 100,000 students. That experience taught me how to think about users, prioritize ruthlessly, and work across functions. I carried all of that into software engineering. My core stack is TypeScript, React, Node.js, PostgreSQL, and AWS. I've built full-stack applications, integrated AI services and third-party APIs, and won first place at the Supercell AI Hackathon 2025 as team lead. I'm currently based in Helsinki and actively building at the intersection of product thinking and technical execution. I care about shipping things that actually work for people, not just things that work.…I'm a Product Engineer based in Helsinki with a background that spans both sides of the product-engineering divide.
