• Support DevOps practices including source control, CI/CD pipelines, automated testing, deployment automation, containerization, and cloud operations.

• Experience developing or supporting React Native mobile applications, including mobile lifecycle management, API integration, testing, packaging, and deployment.
• Hands-on experience working with Oracle and/or PostgreSQL, including SQL development, query optimization, database design, transactions, indexing, and data integration.
• Experience with at least one major cloud platform (Azure, AWS, or GCP), including cloud application services, identity management, monitoring, and cloud-native application deployment.
• Strong knowledge of Git, CI/CD pipelines, Azure DevOps, GitHub Actions, Jenkins, Docker, Kubernetes, infrastructure automation, and DevOps practices.
• Experience with secure coding practices, automated testing, observability, troubleshooting, performance tuning, Agile delivery methodologies, and cross-functional collaboration.

• Experience with Infrastructure as Code (IaC) technologies such as Terraform, Bicep, CloudFormation, or similar automation tools.
• Experience using AI-assisted development technologies such as GitHub Copilot, Amazon Q Developer, Gemini Code Assist, Semantic Kernel, LangChain, LangGraph, or related AI engineering platforms.
• Relevant certifications in .NET, Azure, AWS, GCP, Kubernetes, DevOps, Cloud Architecture, or Full-Stack Development are preferred.
