Auditing an Existing Subnet Plan Before a Cloud Migration

Most subnet articles start from a blank piece of paper and end with a clean diagram. That is not the situation most teams are actually in. The situation is a Confluence page from 2019, a router config someone exported last quarter, and a network engineer who swears "the 10.40.0.0/16 is in use somewh...

The Bug That Passed Every Test — And Still Took Production Down

A few years ago, I was working on a backend service that looked completely healthy. Tests were green. CPU usage was normal. Memory looked fine. No obvious exceptions were showing up in the logs. And yet, every few hours, requests would suddenly slow down. Not fail. Just become painfully slow. T...

A GIF re-encode made the file 4.5x bigger. Interframe differencing fixed it.

Cropping a GIF should not make it bigger. Ours did, and not by a little: a 288-frame Foucault pendulum went from 1074 KB in to 4881 KB out, and a 70-frame gun turret went 116 KB to 1232 KB. That is 455% and 1062%. The same thing happened with no crop at all, which is the detail that gives the cause...

Seven interview rounds is a confession that your bar is broken

If you have to go through seven interview rounds, it's not thorough process - it's a hostage situation. A company that needs seven conversations to decide on you is telling you it can't read a signal. So they're going to wear you down until you're the only one left. What long loops actuall...

As I said, Alea AIcta est.

An argument against the intensive use of AI in development is appearing more and more often, and it could be paraphrased like this: "the more code agents generate, the further developers move away from the codebase they are supposed to understand and maintain." And the argument is not without merit...

When Learning to Code Becomes a Loop: Why I’m Choosing to Build

There was a period when I felt like I was making progress as a developer.I was watching tutorials. Taking courses. Learning new concepts. Saving resources. Watching someone build something and thinking, “Okay, I understand this now.” Then I would move on to the next thing. HTML? Done. CSS? I underst...

Bring Your Own Key: Building an AI Portal That Never Touches the Billing

Bring-your-own-key, not another subscription Every few months another "all AI models in one place" product shows up, and almost all of them work the same way: you pay them a subscription, and they resell access to Claude, GPT-4, Gemini and friends at a markup. That's a reasonable business...

Code Review in the AI Era

One thing I have been thinking about a lot recently is how AI is changing not only the way we write code, but also some of the engineering processes we have built around software development. One of the most interesting ones, in my opinion, is Code Review. For a long time, Code Review was never ju...

How I Built Smart Scraper M2M: A Fast ~30ms Scraper API for AI Agents

Building AI Agents with frameworks like CrewAI or LangChain often hits a bottleneck: heavy, slow web scraping that bloats context windows and increases LLM token costs. To solve this, I built Smart Scraper M2M — a lightweight, high-performance web scraper API designed specifically for machine-to-ma...

Why engineers need commercial awareness, not just technical depth

Engineers who only understand the technology, and never the business it serves, hit a ceiling early. The best ones develop commercial awareness — a real sense of how value is created, funded, and sold.

Keeping Mac work alive without pretending awake means safe

A developer usually meets Mac power management through a simple need. A build, local server, download, or agent is still running, and idle sleep would interrupt it. The caffeinate command can be enough for that open lid case. Lid close is a different boundary. An idle sleep assertion does not mean...

A hackathon is a compression test for how you actually work

A hackathon is a compression test for how you work. Everything you'd normally have weeks for gets squeezed into a window measured in hours — scoping, building, integrating, presenting — and what survives that compression tells you a lot about an engineer. Leading SYNTAX TERMINATOR to the top 12 of m...
