Project description

Our client is one of the largest e-commerce platforms in Europe, used by millions of users every day. The company connects sellers - from small businesses to global brands - with customers, offering a vast product selection, fast delivery, and a well-crafted shopping experience.

Designing a vertical-specific user experience for the automotive category as part of company’s key strategic initiative, aimed at transforming the platform from a general-purpose marketplace into a collection of specialized “stores within a store.”

  • Design, build, and maintain scalable backend services and REST APIs using Java/Kotlin and Spring Boot.
  • Develop frontend features using React and TypeScript, working with existing components and Microfrontend architecture.
  • Design and maintain distributed, microservices-based solutions, with a strong focus on code quality, testing, performance, and reliability.
  • Work with Google Cloud Platform (GCP), SQL and NoSQL databases, including MongoDB.
  • Build and maintain technical and business monitoring for developed products and features.
  • Use AI-assisted development tools, such as GitHub Copilot, OpenCode, and other agentic coding solutions, as part of your daily development workflow.
  • Collaborate with engineers, product teams, and other stakeholders to deliver new features and continuously improve the platform.

Frontend

  • Strong proficiency in TypeScript and modern JavaScript.
  • Good knowledge of React and its ecosystem for building user interfaces.
  • Solid understanding of semantic HTML5 and the ability to create responsive layouts using CSS.
  • Practical knowledge of building accessible web applications in line with WCAG standards.
