CTO (currently @NowSecure), Developer, Early Adopter, Collaborator, and Entrepreneur

Hi there! I'm David, a passionate developer, early adopter, and team builder. I'm enthusiastic about entrepreneurship and always eager to chat about solving hard problems.

πŸ”§ My Current Projects & Contributions

  • πŸ“± At NowSecure, I work with the product development, engineering, and mobile research teams to enable automated mobile app security solutions at scale
  • 🎩 Although a significant portion of my work remains private, I enjoy contributing while hacking on hobby projects. Recently I experimented with the openapi-generator project, with a focus on enhancing and fixing the Erlang client generation. In the past, I developed a Node.js API client for the Google Play Store to download APKs. I rewrote that client in Rust here, which was forked by EFF.
  • πŸš€ As someone with a lot of experience with mobile technologies, reverse engineering, security, privacy, and technology teams, I love collaborating on all sorts of challenging problems and projects.
  • πŸ› οΈ You'll often find me using tools like Frida, Radare, and working on projects involving iOS or Android, mitmproxy, and more.
  • 🐳 I've been an early adopter of many technologies, including Docker and some handy articles back in the early days.
  • 🧠 Recently I was exploring the potential of OpenAI's ChatGPT in various applications and also toying around with GitHub Codespaces and GitHub CoPilot.
