Software engineer at Habits. I build the product — the screens, the APIs, and the pipelines that have to hold up for real customers.

My experience

Software Engineer

Habits Inc.

Full-stack engineer building AI-assisted product features with React, Node.js,TypeScript, python,and AWS. Worked on ideas until they became real production-ready products that are used by large scale consumers.
