How to apply

Along with your CV, please send us a brief, evidence-based application demonstrating how you work with AI-assisted development. Share links to relevant GitHub or GitLab projects and briefly explain what you built, which AI tools you used, and how you used them. We’d also like to understand what was generated by AI and what you personally designed, reviewed, fixed, tested, or improved. If available, mention testing, CI/CD, deployments, active users, or other real-world usage.
