Final answer:
The programmer specializing in the last step of the programming process, which is testing, is called a software tester or quality assurance engineer.
Step-by-step explanation:
The type of programmer who specializes in the last step in the six steps of programming is referred to as a software tester or quality assurance (QA) engineer. The six steps in programming, referred to as the software development life cycle (SDLC), typically include: requirements gathering and analysis, design, implementation or coding, testing, deployment, and maintenance. The testing stage, which the QA engineer is largely responsible for, involves identifying and rectifying bugs or errors in the software code. This role requires a keen eye for detail and a comprehensive understanding of software algorithms and coding.
