Reviews

Sergey Ryzhkov is a professional specialist with a high level of technical competence, efficiency, and attention to detail. Most reviews highlight his competent work, understanding of tasks, quality execution, clean code, and willingness to assist at all stages of a project. However, there are two negative reviews: one points to a cessation of communication and account deletion without completing the work, while the other mentions missed deadlines and incomplete task execution, which led to client dissatisfaction.
