Quick answer
Hiring a custom WordPress plugin developer means finding someone who can translate your goals into secure, performant, and maintainable code. Focus on proven plugin examples, adherence to WordPress coding standards, a clear testing and deployment process, and ongoing support. A good developer explains tradeoffs and communicates timelines clearly.
Hiring checklist
- Define scope: list features, integrations, user roles, expected traffic, and any privacy or compliance needs.
- Review work: ask for plugin demos, GitHub or code samples, and references from past clients.
- Coding standards: ensure they use WP APIs, nonces, sanitization/escaping, and follow PHP and JavaScript best practices.
- Testing & staging: confirm they use automated tests, code reviews, and a staging environment before production deploys.
- Deployment & maintenance: agree on update cadence, compatibility testing with major WP releases, documentation, and emergency support.
- Contract & budget: clarify fixed-price vs hourly, milestones, IP ownership, and acceptance criteria up front.
Key interview questions
- How do you handle security and data validation? Look for specifics about nonces, escaping, and prepared statements.
- Can you show a plugin you built and explain the architecture? Reading real code is the best indicator of skill.
- How do you test for compatibility and performance? Ask about profiling, caching, and compatibility matrices.
- What is your support and bug-fix policy? Make sure response times and SLAs are clear.
- Who will own the code? Confirm license and intellectual property terms in writing.
