Employment Type: Freelance/Independent Contractor (40 hours/week)

Project duration: 2-4 months

Project Overview:

We are kicking off a short-term, high-impact project focused on integrating a partner application with our platform. The main goal is to seamlessly migrate users and their data to our cloud infrastructure, ensuring the existing frontend and backend operate flawlessly within the new environment.

Key Responsibilities:
  • Integrate the existing client-facing application with our internal services and APIs.

  • Adapt and enhance UI/UX components to support migration workflows.

  • Modify and optimize backend logic (Node.js/TypeScript) to ensure correct data mapping and communication.

  • Troubleshoot and resolve integration-related bugs quickly during the testing and rollout phases.

Requirements:
  • 5+ years of commercial Full-stack development experience using TypeScript.

  • Deep knowledge of Node.js (NestJS / Express) and modern frontend frameworks (React or Vue).

  • Solid experience with REST APIs, WebSockets, and authentication mechanisms (OAuth, JWT).

  • Ability to quickly read, understand, and debug someone else's code.

  • High autonomy: capable of taking ownership of a task from start to finish without granular specifications.

Nice to have:
  • Prior experience in projects involving system integration or user base migration.

What We Offer:
  • Competitive Full-Time Project Rate: Competitive compensation based on a 40-hour work week, paid monthly.

  • 100% Remote & Autonomy: This is a full-time commitment (40 hours/week), but you have the freedom to build your own daily schedule. Our core team operates in the CEST timezone (GMT+02:00), so you'll just need to ensure a few hours of overlap with us for daily syncs and collaboration.

  • Zero Bureaucracy: Fast onboarding, direct communication with the team, and no unnecessary corporate meetings. You are here to build.
