What I'm looking for

I’m looking for senior frontend roles where I can lead architecture, mentor engineers, and build high-quality, performant user interfaces in a collaborative team.

I am a senior frontend engineer with 9+ years focused on building user-centric interfaces using modern JavaScript frameworks such as React, Vue, Svelte and related toolchains. I have led frontend feature implementation, mentored UI developers, and delivered production applications including a crypto exchange, fee-payment portals, and large-scale hotel booking UI components.

I consistently improve code quality, type safety and performance while collaborating with backend teams (Django, Node/Express) to ship reliable products. I seek opportunities to drive front-end architecture, grow teams through mentorship, and deliver delightful, accessible user experiences.
