Hey, I'm Pavlo Piliuiko aka Eakzit, a Frontend/Full-Stack Engineer specializing in building high-performance, scalable web and mobile applications with modern JavaScript ecosystems. I focus on crafting clean, maintainable architectures with strong attention to performance, accessibility, and long-term scalability.
Over the past several years, I've worked extensively with React, Next.js (App Router), TypeScript, and modern state management solutions including Redux Toolkit, Zustand, and React Query. I've built production-grade applications using SSR, SSG, and ISR strategies, with a strong focus on Core Web Vitals, SEO optimization, and real-world performance tuning.
My frontend stack also includes Tailwind CSS, shadcn/ui, Framer Motion, and component-driven development with Storybook. I've designed and maintained scalable UI systems, implemented design systems, and integrated REST and GraphQL APIs into complex applications with strong TypeScript safety and architectural consistency.
I also have extensive React Native experience, having built and shipped multiple mobile applications to production. These include apps published on the App Store and Google Play, some of which gained strong user adoption and real-world usage. My mobile experience covers performance optimization, native module integration, navigation architecture, offline-first patterns, and working with libraries such as React Navigation, Reanimated, and Expo (as well as bare React Native setups).
On the backend side, I have solid mid-level experience working with Node.js and NestJS, building RESTful APIs, authentication systems (JWT and session based), and working with PostgreSQL and MongoDB. I've used Prisma and TypeORM for data modeling and worked on designing API layers that scale well in full-stack applications. While backend is not my primary focus, I am comfortable contributing across the stack when needed.
Additionally, I've worked with modern backend-adjacent tools such as Strapi and Directus for headless CMS solutions, and integrated third-party services including Stripe, Firebase, OAuth providers, and real-time communication services in production systems.
I continuously improve my engineering skills and stay current with modern React patterns, server components, edge rendering, and frontend performance optimization techniques. I also explore system design principles and backend scalability concepts to strengthen my full-stack engineering perspective.
I enjoy building end-to-end products, from UI architecture to API design and deployment, and I care deeply about clean code, developer experience, and delivering reliable software. If you're looking for a frontend-focused engineer with strong React Native experience and practical backend capability, I'd love to connect.
