Hi, I'm Ellen — a full-stack web and app developer with a background in Android development and a growing focus on modern web technologies.
Over the past two years, I've built a variety of projects including an AI-powered web chatbot and ecommerce store demo.
I recently led a 6-month solo developer role at a startup, designing and building an end-to-end cashback gift registry platform using React, Node.js, and PostgreSQL.
What drives me is the challenge of problem-solving and the excitement of building intuitive digital experiences. I enjoy merging design with functionality and adapting quickly to new technologies and workflows.
When I’m not coding, I love playing ARPG & strategy games and painting — both of which fuel my creative thinking in tech. I just started to try Dev notes to record my progrss and learning, I added it below.
