What I'm looking for

I'm open to remote frontend work where I can build business-critical web applications, improve performance, modernize legacy systems, and shape scalable frontend architecture.

At Kaspi.kz, I build seller-facing marketplace interfaces for thousands of merchants, covering product listings, inventory, and order management. I reduced repeated page transitions from 3+ seconds to around 0.5 seconds by introducing stale-while-revalidate caching.

I've modernized legacy JavaScript into TypeScript, led a Vue 2-to-Vue 3 Composition API migration, moved builds from Webpack to Vite, and re-architected frontend code around Feature-Driven Development. I also built a secure partner-support tool embedded in CRM through iframe and postMessage.

Previously at Discovery Studio, I built code-hosting, healthcare SaaS, and enterprise real-estate products with Vue, Nuxt, React, Next.js, GraphQL, and scalable component architectures. I interview frontend candidates and mentor a junior developer through reviews, pairing, and day-to-day guidance.
