Notes
- Joined Cognition in Aug 2025 after Cognition acquired Windsurf (July 2025); his announcement reads verbatim: "Update: Excited to be joining Cognition to work on the ML models driving the future of software engineering!"Aug 22, 2025Update: Excited to be joining Cognition to work on the ML models driving the future of software engineering!
- On X he wrote verbatim: "One of the most exciting things about Cognition is the research that our ML team is cooking on a daily basis. Glad to have been a part this effort."Jun 9, 2026One of the most exciting things about Cognition is the research that our ML team is cooking on a daily basis. Glad to have been a part this effort.
- Listed as a co-author of Cognition's SWE-1.6 Preview and SWE-1.6 release posts (authors include Carlo Baronio, Ben Pan, Sam Lee, Eric Lu, Steven Cao, Rohan Choudhury, Adam Zweiger, Ray Wang, Gary Chang, Silas Alberti); SWE-1.6 shipped GA in Windsurf at up to 950 tok/s.Apr 7, 2026
- Windsurf inference team: he thanked "my Windsurf teammates Brian Shimanuki Jonathan Ma Kaushik Varadharajan Cheng-Yuan Lee Benjamin Bajd. It was a privilege to make GPUs go brrr with you all on model inference." - so his Windsurf work was model-serving/inference, not product engineering.Aug 22, 2025Update: Excited to be joining Cognition to work on the ML models driving the future of software engineering!
- At Cognition he named his new ML research/infra collaborators verbatim: "Silas Alberti Gary (Bin) Chang Emile Timothy Anand Jacob Teo, and many others. We're just getting started!" Silas Alberti leads much of Cognition's model research.Aug 22, 2025Update: Excited to be joining Cognition to work on the ML models driving the future of software engineering!
- Joined Windsurf (Codeium) as ML Engineer in Jan 2025, "Working on inference for the models powering the first agentic coding IDE"; current Cognition role: "Working on ML research and infrastructure to shape the future of human software engineering".Jan 2025
- Co-author of Cognition's SWE-1.7 post (RL on a Kimi K2.7 base; multi-cluster training across three continents), alongside Gary Chang, Steven Cao and Silas Alberti.Jul 8, 2026
- Co-author of Cognition's "Introducing FrontierCode" blog (June 2026) with Eric Lu, Ben Pan, Deniz Birlikci, Sam Lee, Rohan Choudhury, Fermi Ma, TC Qin, Carlo Baronio and Silas Alberti, per an arXiv citation.Jun 2026
- Co-started MIT's security club and CTF team, TechSec (per his About page).Jan 24, 2019
- Spent Jan 2019 to Sep 2024 at Apple as Senior Secure Enclave Engineer on CoreOS, "Building a security-critical OS and embedded firmware in the Secure Enclave Processor (SEP)"; a jump from low-level security to ML inference in 2025.Jan 2019
- DEF CON CTF Qualifier 2017: TechSec teamed with Lab RATs (Lincoln Lab's CTF team) and RPISEC, placed 10th and qualified for DEF CON CTF 2017; he worked the weekend with Rahul (fortenforge) at Lincoln's BeaverWorks space.May 3, 2017
- On X, the day SWE-1.7 was published (2026-07-08), he posted verbatim: "We know model training."Jul 8, 2026We know model training.
