Rockstar🎓
Top SchoolKen Micklas is a Senior Software Engineer in London with 13 years of experience building robust back-end systems and cross-platform tooling at companies including Bloomberg, Uber, and Google. He combines production-grade engineering at scale with deep open-source involvement in systems-level projects—contributing fixes and build improvements to notable repositories like rust-lang/rust and the Haskell Cabal ecosystem. His work spans backend, QA, and full-stack concerns, with practical expertise in build systems, mobile platform support, WebSocket/hydration reliability for FRP web apps, and type-safe SQL libraries. Colleagues rely on him to unstick tricky build and portability problems and to improve code correctness and maintainability across complex codebases. Notably, he has hands-on experience enabling mobile builds on Nix-based platforms and adding cursor navigation to Rust’s BTreeSet—small, low-level changes that yield outsized developer ergonomics.

reflex-frp/reflex-dom
Jul 2018 - Sep 2019
Web applications without callbacks or side-effects. Reflex-DOM brings the power of functional reactive programming (FRP) to the web. Build HTML and other Document Object Model (DOM) data with a pure functional interface.
Role in this project:Full-stack Developer
Full-stack DeveloperContributions:1 review, 23 commits, 9 PRs in 1 year 2 months
Contributions summary:Ken focused on improving the reflex-dom library by addressing several aspects. They refactored the WebSocket implementation to use text frames instead of binary, enhancing data handling. The user also made adjustments to the hydration process, ensuring that the hydration tests are reliable by implementing retries and a new network namespace. Furthermore, they updated the tests and utilities.
