Requirements: - Commercial full-stack development experience across .NET and Angular (v12+) for 2+ years. - Solid command of the Microsoft .NET technology stack, including .NET Framework and .NET Core. - Strong Angular (v12+) and RxJS skills. - Expertise in complex SQL Server queries (JOINs, CTEs, window functions, performance tuning). - Solid experience with MongoDB (aggregation pipelines, indexing, schema design). - Experience with event-driven architecture and message brokers (RabbitMQ or Azure Service Bus). - Experience with Entity Framework Core and ORM performance implications. - Proven experience with legacy codebases and microservices migration. - Hands-on experience with Redis caching strategies (cache-aside, write-through, TTL). - Working knowledge of Claude Code. - Level of English – from Intermediate+ and above.

Nice to have: - Experience in the travel industry or with booking/reservation systems. - Experience building SPAs, specifically with Blazor. - Knowledge of Docker, Kubernetes, and containerized deployments. - Exposure to version control software (GitHub preferred).
