Senior Frontend Engineer | React Developer | TypeScript | Next.js | E-commerce | Web Performance | Based in Poland 🇵🇱

Frontend Engineer specializing in React and TypeScript, building scalable web applications and complex user interfaces.

Over the past few years I’ve been working on production React applications used in large-scale products, focusing on maintainable frontend architecture, performance, and reliable UI behavior in data-heavy environments.

Currently working on a large-scale e-commerce platform for a UK online retailer. The platform includes complex user flows such as product discovery, checkout, payments, and order management. My work focuses on developing React components, improving frontend architecture, and refactoring legacy code while keeping production systems stable.

I regularly work with React, TypeScript, and modern frontend tooling to build reusable UI components, integrate with backend services and REST APIs, and improve performance through techniques like code splitting, lazy loading, and render optimization.

Earlier I worked on enterprise automotive platforms where I built data-heavy dashboards and internal tools used by employees to analyze operational data and manage service workflows.

I enjoy working in cross-functional teams with backend engineers, QA, designers, and product managers to deliver production-ready frontend features.

Tech stack: React, TypeScript, Next.js, Redux Toolkit, TanStack Query, JavaScript (ES6+), REST APIs, Webpack, Jest, React Testing Library, Cypress.

Based in Poland (EU timezone). Open to remote opportunities across EU, UK, US, and Asia-friendly timezones.
