Zhanarys Mataev

I’m a Senior Frontend Engineer with 8+ years of experience specializing in building complex, high-performance web applications. I bring structure to “chaos” by refactoring vibe-coded projects into maintainable, scalable architectures.

I’ve led modernization and migration efforts, including refactoring a chaotic codebase into a structured system and migrating 8 core business modules from the Freshworks environment into a standalone high-performance Next.js application. I optimized performance to achieve a 2x–3x speed increase and significantly improved Core Web Vitals, while keeping frontend stability and data integrity during database migration.

I also thrive on product development—co-architecting and building No-code Website Builders and custom Enterprise CRM systems from scratch, plus designing a dynamic UI engine with React and TypeScript for drag-and-drop workflows. My background spans fintech (banking services), e-commerce (medical equipment marketplaces), and hybrid WebView solutions, and I’m driven by reducing technical debt and shipping reliable user-facing value.
