About David Andrea
Software engineer and educator based in Canada, working remotely
💻
Full-Stack Development
Building end-to-end web applications with modern frameworks and best practices
🚀
DevOps & Infrastructure
CI/CD pipelines, containerization, and Kubernetes-based platforms
📚
Technical Writing
Engineering tutorials that bridge educational theory and practice
Background
I design and ship full-stack web apps end-to-end—from product exploration through production-ready delivery—while building the CI/CD automations that keep them healthy.
I'm just as curious about the systems around the code. I experiment with Kubernetes-based platforms to understand how teams operate at scale, and I write about how educational theory can improve how we teach coding and mathematics.

Thoughts on engineering, performance, and developer experience.
Why is Java so dumb?
Java’s data types, wrapper classes, and concurrency helpers look excessive until you see the trade-offs they unlock.
Why JavaScript is so hard for beginners
Legacy syntax, paradigm overload, and a forgiving runtime make JavaScript tough on newcomers, but understanding those quirks helps.
