Strong experience with React, Next.js, or similar frontend frameworks.
Solid understanding of APIs, web architecture, and data modeling.

Comfortable working in a collaborative, product-driven engineering team.
Interest in building systems related to user growth, subscriptions, or customer lifecycle.
