• 3+ years of experience in NestJS or similar backend frameworks (e.g., Express.js, Koa.js).
• Strong experience with microservices architecture and distributed systems.
• Proficiency with messaging systems such as Kafka or MQTT.
• Hands-on experience working with Socket.IO or native socket programming for real-time applications.
• Experience with cloud platforms Google Cloud Platform (GCP) and Amazon Web Services (AWS).
• Solid understanding of containerization technologies, with exposure to Kubernetes for container orchestration.
• Strong proficiency in modern programming languages such as JavaScript/TypeScript (Node.js) and/or Go / Rust.
• Familiarity with CI/CD pipelines and version control systems (e.g., Git).
• Experience with databases (SQL/NoSQL) and caching technologies (e.g., Redis).

Preferred Qualifications:

• Experience working with video streaming protocols (e.g., HLS, RTMP, WebRTC).
• Proficiency in Go or Rust for building high-performance backend services.
• Experience working in an agile environment with a strong emphasis on continuous improvement.
