• Expertise in containerized application development and management. Preferably with a strong familiarity of Docker & Kubernetes, including deploying, managing, and scaling containerized applications, as well as troubleshooting and optimizing workloads within a cluster.

• Proficiency with RESTful API design, data visualization, database architecture (SQL/NoSQL), and version control (Git).

• Familiarity with CI/CD pipelines, DevSecOps practices, and automation tools (e.g., Jenkins, GitLab CI/CD, Terraform, Ansible).

• Experience with front-end frameworks and responsive design principles.

• Experience with cloud platforms (AWS, Azure, or Google Cloud) and infrastructure as code (IaC).

• Strong debugging and performance optimization skills for distributed systems.

What Desired Skills You'll Bring:

• Experience with Kafka, RabbitMQ, NATS , or message-driven architectures.
