  • Integrate SQL Server stored procedures and optimize database queries.
  • Implement authentication, session, and access control aligned with CI4.
  • Deploy applications on IIS servers and Dockerized Azure environments.
  • Implement CI/CD pipelines and manage Azure App Services deployments.
  • Ensure testing, documentation, and security best practices are followed.

  • Microsoft SQL Server, T-SQL, Stored Procedures, Views, Triggers
  • IIS (Windows Server 2019/2022) configuration & optimization
    DevOps / Cloud:
  • Docker containerization (multi-stage builds, networking, volumes)
  • Azure Cloud Services (App Service, Azure SQL, Container Registry, Key Vault)
  • CI/CD pipelines (GitHub Actions, Azure DevOps, or Jenkins)
  • Version Control: Git (GitHub / GitLab / Bitbucket)
    Tools & Supporting Libraries:
  • Composer, PSR-4 autoloading, Namespaces
  • PHP extensions: SQLSRV, intl, gd, zip
  • ENV configuration for multi-environment setup
  • PowerShell or Bash scripting for deployment

Preferred Experience

  • Experience upgrading CI2 to CI4 with functional and database parity.
  • Migrating CI2 sessions, routes, and libraries to CI4 equivalents.
  • Working knowledge of API-based integrations (e.g., reCAPTCHA, payment gateways).
  • Exposure to WordPress or Bedrock setups (bonus).
  • Knowledge of Windows Docker containers and hybrid deployment scenarios.
  • Certifications in PHP, Azure, or DevOps are a plus.
