• Containerize and deploy solutions using Docker/Kubernetes in cloud environments (AWS/Azure)
• Ensure application security using OWASP standards and best practices
• Collaborate with clients to gather requirements and deliver technical solutions
• Produce technical documentation, system designs, and process flows
• Support testing, deployment, and continuous improvement efforts
