Rockstar🎓
Top SchoolDmitry Kutakov is a Senior Backend Engineer based in Berlin with 13 years of experience building high-throughput, production-grade systems across startups and large companies. He has designed and scaled real-time data platforms (from 2k to 6M events/sec) and owned resilient ML-backed recommendation services with 99.95% uptime at Snap, combining Go, Python, Kubernetes, and cloud-native tooling. A practical engineer who moves between hands-on coding, CI/CD and infrastructure, he championed API-first design, observability and reproducible builds while founding backend standards and on-call practices. Dmitry is also an active open-source contributor to prominent Go projects like gin-gonic/gin and urfave/cli, improving test coverage, error handling and form mapping logic—work that reflects his focus on quality and maintainability. He often brings less obvious strengths to teams: turning ad-hoc prototypes into fully automated, secure deployment pipelines and mentoring others through shared knowledge sessions.
