@[email protected]Hello, I'm Henry Hiles, a developer specializing in flutter and web development. I'm proficient with Dart, Astro, Node.JS, and TypeScript. I build high-performance, intuitive applications with clean, efficient code and modern design principles.
Always eager to learn, I’ve earned certifications from Microsoft, Google, and Meta in cloud computing, AI, and cybersecurity. Whether I'm optimizing mobile apps or designing websites, I’m passionate about delivering innovative digital solutions.
I am into #foss, #linux, #nixos, #selfHosting and #postmarketOS.
I occasionally boost posts without alt text (mostly of raccoons or cats, nothing important).

@[email protected]Security engineer & distributed systems nerd focused on AI, cloud, and zero-trust architectures. I care about verifiable training, confidential computing, and making “secure by default” actually real. I write, tinker, and ship odd little projects that live somewhere between research and production. When I’m not building and breaking, I’m probably alpineering, swimming, or on the airwaves.
