Hiring a web developer is one of the most important decisions a business can make for its online success. The right developer builds more than just pages — they create experiences that convert visitors into customers. But how do you separate the good from the mediocre? Here are the key traits to look for when hiring a web developer.
A good web developer has a solid understanding of the core technologies: HTML, CSS, and JavaScript. For more advanced projects, familiarity with at least one backend language (PHP, Node.js, Python, Ruby) and a database (MySQL, PostgreSQL, MongoDB) matters. They should understand version control (Git), deployment basics, and how to debug issues.
With most web traffic coming from mobile devices, a developer must prioritize responsive design. This goes beyond simply making things shrink — it involves rethinking layout, images, touch targets, and performance for smaller screens.
Fast websites convert better and rank higher in search engines. A skilled developer knows how to optimize images, minimize HTTP requests, use caching, and implement lazy loading. They can measure performance using tools like Google PageSpeed Insights or Lighthouse and interpret results.
Even if you hire a separate designer, developers should have a good eye for spacing, typography, and visual consistency. Small details—consistent paddings, properly scaled images, crisp icons—make a big difference in perceived quality.
Web development is mostly problem solving. A great developer breaks down complex issues, reproduces bugs, and finds efficient fixes. They don’t just patch problems; they find root causes to prevent recurrence.
Clear communication saves time and reduces misunderstandings. Look for developers who explain technical concepts in plain language, provide progress updates, and ask clarifying questions. This is especially important for remote work or cross-functional teams.
A developer who understands the basics of SEO (clean URLs, semantic HTML, meta tags) and accessibility (proper ARIA roles, keyboard navigation, alt text) adds extra value. These practices expand reach and reduce legal or usability risks.
Security can’t be an afterthought. The developer should follow best practices: validate inputs, protect against SQL injection and XSS, use HTTPS, and handle user authentication and passwords correctly.
A good developer writes reusable code and tests it. This includes unit tests, integration tests, or at least manual testing across browsers and devices. They use staging environments for safe testing before pushing to production.
Web tech evolves fast. Developers who learn new frameworks, follow best practices, and adapt to changes bring long-term value. Ask what they learned recently or which blogs, podcasts, or communities they follow.
Delivery matters. A dependable developer sets realistic timelines, meets deadlines, and communicates early if things go off track. Check references and past project delivery records.
Building a website often requires working with designers, marketers, and product owners. Collaboration skills, the ability to accept constructive feedback, and empathy for end users differentiate great developers.
Portfolio review: Check live projects on mobile and desktop; assess performance.
Code samples: Review GitHub or code snippets for readability and structure.
Technical interview: Ask scenario-based questions, e.g., “How would you debug a slow page?”
Trial task: A short paid task replicating real work shows skills and communication.
References: Speak with past clients about reliability and problem solving.
Vague answers about past projects or unclear role.
Over-reliance on templates without customization.
Poor communication or missed deadlines during hiring.
No concern for performance, security, or accessibility.
