Solid understanding of Docker and containerization concepts. Experience deploying applications into private cloud or on-premises virtualized environments. Strong experience with SQL Server; additional experience with Postgres/MySQL is a plus. Ability to support and modernize legacy on-premise applications while designing new cloud-hosted replacements. Working knowledge of API design, REST, GraphQL, microservices, and distributed systems. Hands-on experience with AI-assisted development tools. Familiarity with Git, GitHub, Bitbucket, or Atlassian Preferred Skills Experience converting monolithic applications into microservice or container-based architectures. CI/CD engineering with GitHub Actions, GitLab CI, or Jenkins. Strong UX/UI fundamentals, wireframing, and component-driven design. Familiarity with authentication systems (OAuth2, SAML, JWT). Exposure to distributed logging and monitoring platforms such as Sentry. Experience working with Atlassian tools (Jira, Confluence) and formal change-order or ticket-based development workflows (helpful but not require) Background in logistics, ERP, or enterprise operational platforms is a strong plus.
