Denis Isaev — Infrastructure Engineer
I am an infrastructure engineer and former CTO. I currently work on core cloud infrastructure and reliability at Yandex Cloud. Before that, I spent six years at Yandex Go and six years at VK.
I am looking for Senior Staff+ individual-contributor roles in London and across the UK, particularly in cloud and AI infrastructure, compute platforms, developer infrastructure, and reliability. I hold a UK Global Talent visa and do not require sponsorship.
Selected work
Reliability at Yandex Go. Led a twelve-month programme that improved availability from 99.9% to 99.99% across a backend of approximately 800 microservices. One of the resulting investigations connected retries to load amplification and a metastable failure state, compared recovery strategies through simulation, and led to retry budgets in shared client infrastructure. Read the case study in English or watch the talk in Russian.
Performance at Yandex Go. Led cross-system work that reduced median main-screen load time by 2.4 seconds and introduced performance budgets for new features. Watch the talk in Russian.
Go developer tooling. Created golangci-lint, now widely used in the Go ecosystem, and go-queryset. Watch my GopherCon talk on Go linters.
