The person behind
the builds
Software Engineer
I enjoy building practical applications, APIs, and tools that solve real problems and are reliable enough for people to actually use.
Systems Thinker
I like understanding how pieces fit together, from frontend interfaces to backend services, databases, data pipelines, and deployment decisions.
Data-Focused
I’m drawn to problems where good software makes messy information easier to validate, analyze, search, and turn into useful decisions.
Community-Driven
As an RA and mentor, I know technical work does not happen in isolation. Communication, trust, and empathy matter as much as code.

Building
Full-stack, mobile & data tools
I'm a Columbia University undergraduate studying Computational Biology with a strong focus on computer science, software engineering, and data-driven systems. My work sits at the intersection of building useful products, designing reliable backends, and using code to make complex information easier to work with.
Outside the classroom, I've built full-stack applications, mobile tools, Chrome extensions, REST APIs, database schemas, and AI-powered developer tools. I learn best by building, debugging, and shipping projects that real people can use.
