  • Implement secure coding, automated testing, and DevSecOps CI/CD practices.
  • Develop and maintain cloud-native applications using AWS or Azure.
  • Troubleshoot, optimize, and enhance existing applications.

Required Skills

  • Programming: Python, Java, JavaScript, TypeScript, Node.js, or C#/.NET.
  • Frontend: React, Angular, or equivalent modern frameworks.
  • Backend: FastAPI, Django, Flask, Spring Boot, Express.js, or .NET Core.
  • API Development: RESTful APIs, microservices, JSON, API integration.
