What I'm looking for

I'm open to remote Senior Frontend, Full-stack, or Frontend Tech Lead roles, full-time or B2B contract. I'm growing into framework-agnostic full-stack work with Node.js, while keeping tech leadership as a permanent part of my role.

At LenderKit, I lead frontend development for a crowdfunding platform with complex payment and compliance flows. I led the frontend of a new product version, migrating from Vue 2 to Vue 3 with a full redesign, and launched and supported four client platforms built on the shared product foundation.

I build payment and KYC/AML integrations, including asynchronous verification flows and Arabic RTL interfaces. I also review code, mentor developers, and write open-source Vue libraries; outside of work, I use Nuxt and Node.js on a personal information catalog.
