Listens to a lot of #music, spends leisure time playing #games and tries to read #books to absorb new ideas and let my brain wander.

Working in #DataManagement and #DataGovernance to support #Analytics teams and I do a bit of #InfoSec to round it out!

Other hobbies include #camping, #hiking, #snowboarding, #travel, and enjoying way too much good food & drink.

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).

Author of the Quantum Time Machine's best documentation:: the #qmec \

Writing and designing and coding mostly for women in tech and Indigenous peoples

A Fediverse OG, but my followers count here on infosec.exchange turned off; I write for specific audiences, **not** to accumulate irrelevant numbers of "reactions" from an audience that includes Meta Platform Inc.'s bots built to deceive.

BTW, I built a free, open-source Ruby-based framework that "literally millions" in the SF Bay and PDX metro used on HTTPS. Code was later turned into a "Wordpress App" and an app that is now on Google Play; bigger numbers of millions of people use it.
