Сопроводительное письмо
I am writing to express my strong interest in the Senior Backend Engineer position for the PerfectScale platform at DoiT. With over 6 years of experience in backend development and a deep specialization in Golang, I have spent the last few years building high-load distributed systems that align perfectly with the technical challenges described in your posting. My background includes extensive work with microservices, Docker, and Kubernetes, which are central to the PerfectScale mission of cloud optimization.
In my previous roles, I have consistently focused on writing clean, maintainable code and proactively addressing technical debt—a practice I am pleased to see integrated into DoiT's culture with your dedicated 'housekeeping' days. I have significant experience with PostgreSQL and ClickHouse, and I am particularly excited about the opportunity to contribute to a data-intensive SaaS product that empowers DevOps and SRE teams. I am confident that my proactive approach and technical expertise in Go and cloud infrastructure will make me a valuable asset to your EMEA engineering team.
