Johanna Hendrix

👋

Hi, I'm Johanna Hendrix

I'm a passionate Full Stack Developer who thrives on building innovative software solutions.

Originally from Germany, I have been living in the U.S. for 25+ years now.

I like building stuff, learning new things, exploring huge datasets, automating workflows, and now: deep-diving into AI and exploring its possibilities.

📝 About Me

Summary

Seasoned full-stack developer with extensive experience crafting modern web applications, sophisticated cloud architectures, and data-driven solutions. Passionate about efficient code, optimizing cloud costs, delivering exceptional user experience, and lately: leveraging AI to eliminate any human-powered tasks that LLMs can be trained to do (safely and accurately)

Current favorite tech stack: Next.js 15 with server components, TypeScript, C#/.NET for back end services, and either serverless / event-driven architectures using proprietary cloud services or VPS deployments using open source packages (depending on use case, traffic, and budget).
