I’m looking for a role where I can work on challenging frontend problems, have ownership over what I build, and continue growing as an engineer. I value strong engineering culture, interesting products, and a team where people share knowledge and give constructive feedback.

I build high-performance React products for banking and consumer marketplaces.
GeorgiaWhat I'm looking for
At iFellow, I lead frontend development for an AI-powered cybersecurity expertise portal used by a major bank serving 100M+ customers.
I built an embedded LLM assistant with streaming responses, code-highlighted markdown, and background generation, reducing documentation search time by 34%. I also introduced Storybook for a corporate UI Kit, documenting 100+ components and cutting component lookup from 30 minutes to under 2 minutes.
Previously at Naimi.kz, I developed a React, Next.js, and TypeScript services marketplace serving 220K monthly active users. I improved catalog performance to 0.81s LCP and 64ms INP, and built discovery and request flows that reduced search abandonment by 17% and increased request completion by 23%.
I focus on component-driven architecture, accessible interfaces, and measurable product performance. I’ve also mentored junior developers and delivered WCAG 2.1 AA compliance for complex interactive components.
