Product Builder | Tech for Good
Hi, I'm Esther.
I have 5+ years of experience in product and operations, mainly working in the digital healthcare field.
Curious about how things work under the hood, I went back to study Computer Science and recently completed my Master’s at Northeastern University, where I focused on full-stack development and AI-driven applications.
As AI rapidly evolves, coding is becoming a new way to express ideas and build products faster than ever. I’m excited about combining product thinking with technical understanding to create meaningful AI products.
