About the internship

Interested in building real-world software skills and learning from experienced mentors? Our internship program is back — designed as a project-oriented experience where you’ll work on a meaningful topic with the support of an experienced mentor.

From day one, you’ll go through a structured onboarding (similar to what new employees complete) to get familiar with the working environment and processes in an international organization. Together with your mentor, you’ll define the project scope based on your interests and current skills. The internship concludes with a short presentation of what you’ve built and learned, plus two-way feedback.

✅ Important update: this internship is planned with a clear progression path from July 2026 — the first month is an unpaid internship period; after that, we offer a permanent contract (UZ or B2B) and continue with a standard hiring path (formal employment), based on results, engagement, and project needs.

  • Build and enhance features in a real project using .NET 8 (C#) and Vue.js

  • Learn cloud fundamentals by working with Azure App Services, Functions, and Storage

  • Implement and understand authentication/authorization flows (OIDC/OAuth2, JWT)

  • Work with data and reporting basics (e.g., Power BI context and outputs)
