The product includes complex client-side flows such as image handling, media rendering, uploads, previews, downloads, sharing flows, dashboard logic, and external integrations.

We need someone who can work closely with our technical founder, enter an existing codebase, diagnose issues, improve performance, and help make the product stable across devices and browsers.

Relevant experience:

• Strong React / Next.js / modern JavaScript experience

• Strong frontend debugging and performance optimization skills

• Experience with client-side rendering and browser-based media flows

• Experience with image / video / canvas handling — advantage

• Experience with mobile browser behavior, especially iOS Safari — strong advantage

• Backend / API understanding — advantage

• Experience stabilizing MVPs or pilot-ready products — strong advantage

This role is best suited for someone practical, sharp, reliable, and hands-on.
