Develop custom plugins for specific business workflows or integrations.

Write clean, secure, and scalable PHP/MySQL code following WordPress coding

standards.

Optimize database queries and caching mechanisms.

Introduce error-logging and rollback handling for all critical backend updates.

Use Git for version control (feature staging production branches).

Manage CI/CD pipelines for automated build, lint, and deployment processes.

Maintain staging environments for QA validation and UAT.

Perform environment variable and configuration management (via Composer, dotenv,

8. Quality Assurance (QA) & Testing

Define and follow QA protocols across all development stages (unit, integration, and

regression testing).

Conduct functional testing for templates, forms, and custom features before deployment.

Validate cross-browser and responsive layouts using real devices and tools (e.g.,

BrowserStack).

Test API integrations for latency, data accuracy, and error handling.

Perform UAT (User Acceptance Testing) with stakeholders before production rollout.

Ensure accessibility, SEO tags, and analytics events are verified in each release.

Create and maintain test cases and test reports for each release cycle.

Implement automated testing where possible (e.g., PHPUnit for backend,

Playwright/Cypress for UI regression).

Collaborate with PMs and QA reviewers to log issues, track resolutions, and verify fixes

before go-live.

9. Documentation & Knowledge Transfer

Maintain developer documentation for code structure, APIs, and configuration steps.

Prepare handover manuals and changelogs for internal or external teams.

Maintain a QA & Release Log documenting test results, known issues, and resolutions
