Hey, I'm Sonia
A frontend developer who values meaningful impact and user experience in any projects. Welcome to my little corner where I share what I'm up to and what's on my mind 💭
👩💻 About Me
I build thoughtful, user-first digital experiences with end-to-end ownership.
As a Frontend Engineer, I take products from concept to implementation through fast iteration and constant improvement. With 4+ years of experience, I’ve collaborated with cross-functional teams and built products from the ground up across Web3 and EdTech, translating complex requirements into clear, user-friendly experiences.
I thrive on learning, adaptation, and problem-solving.
Born and raised in Hong Kong and now based in Toronto, my multicultural background has shaped an open, flexible mindset. I focus on efficient, high-impact solutions and stay curious about better ways to solve problems.
My goal is to bridge technology with the creative world.
Inspired by music, fashion, and art, I want to build tools and communities that help creatives gain recognition and support. When I’m not coding, I’m exploring styling and content creation!
Right now i'm...
- ✅ Open to any jobs or collabs in tech
- ✅ Building a creative tool - InspoLens !
- ✅ Creating social media content about music & fashion
