Rockstar🎓
Top SchoolIvan Mikushin is a pragmatic principal/staff-level software engineer with 14 years building cloud-native and distributed systems, currently based in San Jose. He specializes in backend and orchestration work—Kubernetes, Rancher, Knative and Tanzu—bringing deep Go experience since 2015 and a history of shipping platform features and controller logic at VMware and Rancher Labs. Recently he’s gravitated to Rust and low-level runtime work, contributing to Wasmtime and implementing Wasm GC, and has also worked on zero-knowledge proof systems like Kimchi and HyperPlonk. Ivan combines systems-level engineering (OS and build infrastructure contributions to RancherOS and multi-arch builds) with developer tooling and CI expertise, having authored internal tools such as a Go vendoring utility. He favors Clojure on the JVM for its Lisp simplicity, reflecting a long-standing taste for expressive languages alongside pragmatic production coding. Notably, his open-source work includes practical refactors and stability improvements to high-profile projects like Knative Serving and Tanzu Framework that improve real-world deployability.

vmware-tanzu/tanzu-framework
Aug 2021 - Jan 2023
Tanzu Framework provides a set of building blocks to build atop of the Tanzu platform and leverages Carvel packaging and plugins to provide users with a much stronger, more integrated experience than the loose coupling and stand-alone commands of the previous generation of tools.
