I was doing a code review for a colleague when I found it. The component had five useEffect hooks. No errors. No warnings in the console. The PM had signed off on it. It had been in production for three months. But there was a subtle bug that only showed up when the user navigated quickly between pages. Data would flash. State would reset. Sometimes the old user's name would appear for a split sec
Why your servers should die after every deployment How many times have you logged into production to "quickly fix" something, only to create a snowflake server that behaves differently than everything else? If this sounds familiar, you're dealing with configuration drift, and immutable infrastructure might be the solution you need. Immutable infrastructure follows one simple rule: never modify a
A pod gets created. It gets an IP. Then it dies. A new pod replaces it. New IP. Now imagine you have ten pods of the same app, and they restart all the time. Which IP do you call? You can't. That's the problem Services solve, and the answer is more interesting than "Kubernetes assigns a stable IP." This post walks the full picture in five parts: why Services have to exist, what happens when you cr
REST has served backend development well for two decades. It is simple, predictable, and every developer on your team understands it. So why are more engineering teams moving toward event-driven architecture? The short answer: synchronous communication does not scale the way modern systems need to scale. And the teams discovering this lesson in production are paying for it in outages, latency spik
Twenty-four hours after I swapped Supabase Auth's default SMTP for Resend, my first real user signed up. I'll call him K. I emailed him three questions. He replied in 49 minutes: "make a better ui of admin so we can use." That sentence is now my Q2 roadmap. Three weeks into launch I have 3 users, 2 Google clicks, and zero mentions when you ask ChatGPT or Gemini for "free status page alternatives."
Jack had finally stepped into the world of Docker. It felt like magic, but Jack was never one to just believe in "magic spells." He was curious. He wanted to look under the hood and see what actually made Docker so powerful. He had one big question: How could 50 different people live in the same "apartment building" (the Host OS) without accidentally reading each other's mail or eating each other'
Last week I had a problem. I'd built an internal documentation site in Trilium Notes — about 30 notes covering product, marketing, and operations stuff. It was for non-technical teammates who needed to answer questions from developers about the platform. The docs were good. Structured, searchable, complete. But reading 30 notes to find one answer is not great UX, especially for someone who's been
Go is a compiled language — the code is converted into machine‑readable form before execution. From a beginner’s perspective, this means Go catches many errors during compilation, giving you cleaner, faster, and more predictable performance at runtime. Go is widely used for: API development CLI tools Microservices architecture Backend server. DEVOPS activity So it fits perfectly with the kind of
