I build scalable React and Next.js web applications with TypeScript, polished UI, and performance-focused architecture.

I've built scalable web applications at Abz.agency using React, Next.js SSR/SSG, and TypeScript, owning features from requirements and architecture through production support.

I developed an admin panel, KYC/KYB verification flows with Jumio and Kyckr, manual document-review tools, and real-time client-admin updates through WebSockets. I also worked with backend engineers on APIs for verification and document handling.

I reduced bundle size by 30% through code splitting and lazy loading, while building reusable UI components with SCSS, MUI, and Storybook. My work includes REST API integration, caching with SWR and TanStack Query, and authentication with NextAuth and JWT.

I'm currently contributing production features for WinWin's travel-tech platform with React 19, TypeScript 5, Tailwind CSS, Radix UI, Zustand, and TanStack Query. Earlier, I delivered websites and WordPress projects for small-business clients.
