Web development costs the lowest when you hire junior engineers and developers. They are certified but the least experienced in the lot. They lack the skill-set to fast-track full-stack or full-cycle back-end requirements alone. Hence, junior developers are usually hired in numbers. They cost between $15-$25 per hour based on the tech stack. Advanced-intermediate backend engineers cost between $25 and $55. They have a consummate knowledge of programming based on custom requirements, offering guidance to junior programmers, and applied knowledge of database deployment, testing, and integration. Senior backend experts/engineers/developers have several certifications to vouch for their mastery over given programming language domains. Their average hiring rates range from $75-$150, depending on project scope, additional management duties, etc. These backend experts have full-stack knowledge including migrations and advanced troubleshooting.
