Why You Should Sometimes Reinvent the Wheel

Picture this: You’re knee-deep in a project, caffeine coursing through your veins, when suddenly you need to implement a feature that surely someone has built before. Your colleague leans over and whispers those magic words that every developer has heard a thousand times: “Don’t reinvent the wheel.” But here’s the thing – sometimes that wheel is square, sometimes it’s made of concrete, and sometimes it comes with 47 dependencies that’ll make your bundle size explode faster than your patience during a code review....

Ignoring Industry Trends to Focus on What Works

Picture this: You’re at a tech conference, surrounded by developers evangelizing the latest framework that will “revolutionize everything.” Meanwhile, you’re sitting there with your trusty old stack, wondering if you’re the equivalent of that person still using Internet Explorer in 2023.

The Case Against Always Using Serverless Functions

Serverless functions are the shiny new toy that everyone wants to play with. They promise infinite scalability, zero infrastructure management, and that magical “pay-only-for-what-you-use” pricing model. But here’s the thing: just because you can put everything in a serverless function doesn’t mean you should. Let me be the party pooper who tells you why your serverless-first approach might be costing you more than just money—it might be costing you sanity, performance, and control over your own application....
