Becoming a tech lead was the goal from pretty early in my career. I had a clear picture of what the role was. More responsibility, more influence over the work, more of the interesting problems landing on my desk because someone had to figure them out and that someone, finally, would be me. It read like the natural next step. The thing you graduate to once you're good enough. What that picture did
Introduction Picture two doctors updating the same patient record at the same time - one in São Paulo, the other in London. Both are offline. When connectivity returns, whose changes prevail? This is not a hypothetical. It is the everyday reality of distributed systems: multiple nodes, no shared clock, no guaranteed network. The conventional answer has long been locking - one node waits while an
Introduction Some code works. Some code lasts. The difference rarely comes down to typing speed, syntax mastery, or how many nights you're willing to push through. It comes down to how you think about a problem before you write a single line. Big-O notation is a mathematical framework that describes how an algorithm performs as its input grows. In plain terms, it answers one question:

I have been meaning to upgrade my personal site to Astro 6 for a while. The release notes sat in my open tabs for weeks, and every time I sat down to do it, I found an excuse to work on something else. This week, I finally ran out of excuses. I carved out an afternoon, ran npx @astrojs/upgrade, crossed my fingers, and expected a smooth ride. The dev server crashed immediately with a cryptic error
For years, I called myself a web designer. Then a developer. Then a digital consultant. None of those titles ever felt quite right. Because clients weren't just asking me to build things. They were asking me to solve problems. Slow sites, broken checkouts, confusing navigation, teams that couldn't figure out how to update their own content. That's when I realized what a technology solutions profes
If you use ChatGPT, Claude, Grok, Copilot, or Gemini daily, it feels like you're talking to a person. It remembers what you said three messages ago. It references the project details you shared yesterday. It feels like the model has a persistent brain that is learning about you. But it’s a lie. From an architectural standpoint, an LLM is the most "forgetful" piece of software you will ever use. Ev
I've been working remotely for a while, and most of what I picked up in the first six months turned out to be wrong, or wildly overrated. Not bad advice exactly. Most of it sounds reasonable when you read it. It just isn't doing the work it claimed to. The "wake up at 5am, dedicate a workspace, use the Pomodoro technique, journal every morning" stack is a kind of theater. Some of it helps a little
