## Notes
- Cognition announced 'Welcoming Dioxus to Cognition' on 2026-09-10: Jonathan Kelley and the Dioxus team joined to improve Devin's virtual machine, computer use skills, and testing capabilities, while Cognition continues supporting Dioxus, Blitz, Taffy and Subsecond. (https://cognition.com/blog/welcoming-dioxus)
- Publicly quoted by AWS as 'Evan Almloff, Member of Technical Staff, Cognition' on the EC2 Mac page, word for word: "first week after launch, more than 1,100 customer organizations are using Devin for macOS, and we expect that demand to keep growing as teams do more of their Apple development with Devin.". (https://aws.amazon.com/ec2/instance-types/mac/)
- Dioxus Labs' own post 'Dioxus Labs is joining Cognition' (by Jonathan Kelley) says the team built a cloud coding harness, SkyVM, supporting macOS/iOS, Android, Linux and Windows with handrolled virtualization for VM snapshotting, forking and rollbacks resuming in under 50ms; this is the VM expertise Cognition cited for Devin. (https://dioxuslabs.com/blog/joining-cognition/)
- The Dioxus post states the Devin CLI terminal renderer is built with Dioxus, and Cognition says it 'used Dioxus extensively to build and improve the performance of Devin', so Evan's framework work was in Cognition's product before the team joined. (https://dioxuslabs.com/blog/joining-cognition/)
- Member of Technical Staff at Cognition (2026) after Dioxus Labs was folded into Cognition; LinkedIn lists Software Developer at Dioxus Labs 2023-2026, then Software Engineer there in 2026. (https://www.linkedin.com/in/evan-almloff-571467213)
- Reposted Cognition's 2026-09-15 launch: 'Special delivery: Devin just got a Mac 🍎 Now Devin can: 1. Build & test apps on its own Mac VM with iOS simulator...' five days after the Dioxus team joined. (https://x.com/demonthos/status/2099887912406151290)
- Co-contributor with Jonathan Kelley (and a Devin bot) on DioxusLabs/accessibility-cli, a cross-platform CLI for computer use across macOS, Windows, Linux and Android, which lines up with Cognition's stated computer-use goal for the team. (https://github.com/DioxusLabs/accessibility-cli)
- Beri.net analysis (2026-09-14) notes every crates.io owner of Blitz's core crates and two of Taffy's three owners now work at Cognition, and Blitz underpins Cloudflare's Kitesurf agent browser; Nico Burns was named lead engineer on Blitz devoted full-time to Dioxus. (https://www.beri.net/article/cognition-dioxus-acquihire-blitz-taffy-crate-owners-kitesurf-dependency)
- Dioxus Labs raised $3.5M collectively from Y Combinator and Khosla Ventures (with champions at Futurewei) before joining Cognition; Dioxus started as Jonathan Kelley's side project during the last summer of Covid. (https://dioxuslabs.com/blog/joining-cognition/)

- Creator of sledgehammer-bindgen, described by him as 'the fastest way to get data from Rust into JavaScript' using batched string decoding and per-framework opcode lists. (https://github.com/ealmloff/sledgehammer_bindgen)
- Creator of Kalosm (floneum/floneum), a local-first Rust framework for controllable language, audio and image models, and author of the Kalosm book; he also is a core contributor to the official Dioxus book. (https://evanalmloff.com/)

- I'm currently working on the Dioxus framework and building Kalosm, a library for local AI inference in Rust. I work on high performance ergonomic tools and libraries for developers from carousels to kernels; this comes from the profile summary and preserves the person's own positioning. (https://www.linkedin.com/in/evan-almloff-571467213)
