About

Security researcher turned indie maker. I find and disclose vulnerabilities (CVE-assigned) by day and build Mac and web tools the rest of the time. Currently building JMacy, a fast, native download manager for macOS with a Chrome extension. Also run GreyCore Labs and write crypto explainers at cryptoinbrief.xyz. Always down to talk macOS dev, security, and shipping small products.
