WRITING ARTICLES

I write articles on various topics. I write about mobile app development with Flutter, about Tech Communities, web development, my stories, and anything worth sharing.

The topic list has widened over the years into AI agent tooling, product analytics, authentication and security, backend design and Firebase architecture, Angular and Vue on the frontend, and career notes from the Google Developer Expert path. The pieces vary from short walkthroughs to longer teardowns, and many ship with companion source repositories.

Here are articles I've written over the years. For some, I published them on my blogs. For others, they were guest authorship for blogs like CSS-Tricks and freeCodeCamp, and outlets like Medium, Hashnode, Dev.to, and SweetCode.
