Clean code.
Reliable delivery.

For the past 5 years I've worked on full-stack teams in New York, building Java/Spring Boot services and React front ends for products used by thousands of customers.

I'm comfortable owning a feature end to end, from API design and database changes to UI, unit tests and deployment through CI/CD pipelines.

I like working in collaborative Agile teams, writing readable code, and picking up new tools when the project calls for it.

How I work:
Understand the problem. Write it clean. Test it well. Ship it.
