Caching Is Easy. Production Caching Is Not.

This post is part of the series The True Code of Production Systems. The first time you add caching to a system, it feels like a superpower. One afternoon of work. Response times drop. Database load drops. The whole system breathes easier. You ship it, you move on, and somewhere in the back of your mind you file caching under "solved problems." That filing is the mistake. Because caching in ...

Chatlectify: turn your chat history into a writing style your LLM can reuse

Two years of daily Claude + ChatGPT. They've seen probably a million tokens of my writing. Every response still opens with "Certainly!" or "Great question!" and closes with "In conclusion…". Nobody writes like that. The model has no idea who you are — you're just another session. So I built chatlectify. Point it at your exported chat history (Claude / ChatGPT / Gemini JSON, or a folder of your o...

How to Add Authentication to Any App in Under an Hour (2026 Guide)

Auth is the part every tutorial skips. Here's a complete, honest breakdown of your three real options in 2026. Authentication is where most "build an app in a weekend" tutorials quietly stop. They get you to a working UI, a connected database, maybe a deployed URL — and then assume auth is someone else's problem. It isn't. It's yours, and it's the part that most commonly causes production incid...

How to Optimize React & Next.js Apps for SEO and Rank Faster

I spent 3 hours debugging why Google couldn't see my React app. Turns out, Googlebot was rendering a blank white page — because my entire content lived inside client-side JavaScript that hadn't loaded yet. The fix was 4 lines of code. But getting to those 4 lines cost me a week of confused Google Search Console reports, zero indexed pages, and a growing suspicion that SEO for single-page applicati...

Your AI Sounds Most Confident Right Before It's Wrong — Here's the Data

Let's start with something that took me a while to sit with properly. AI models are 34% more likely to use confident language — phrases like "definitely," "certainly," "without question" — when they're generating incorrect information compared to correct information. Not less confident. More. That's not a bug report from a niche research paper. That's how the system fundamentally works. And if ...

5 Data Patterns That Scream 'Your Developer Is Burning Out

Nobody quits on a Monday. The resignation email you receive on a random Thursday was written — emotionally — six weeks ago. The disengagement started three months ago. And the data saw it coming the entire time. The 2023 Stack Overflow Developer Survey found that over 70% of developers reported some level of burnout symptoms. Replacing a mid-level software engineer costs an estimated 50-200% of t...

AI as a Software Engineer: Limits of Autonomy in Real-World Systems

The narrative that AI will soon replace software engineers is compelling, but incomplete. After working closely with modern large language models in production systems, a more nuanced reality emerges: AI is undeniably powerful, yet fundamentally constrained when operating autonomously in real-world environments. The gap between writing code and owning systems is where autonomy begins to fracture. ...
