Every React component starts innocent.
 Then someone adds something.
 Then another thing.
 And suddenly, you end up with this beauty:

Cats are natural founders. They understand leverage. Why hunt when you can convince a human to become your unpaid operations team?

I’m building SaaSanity. Part landing-page audit. Part founder intervention. Part AI saying, “This hero section is not about the customer, is it?”

Manual coding is dead. Anyway, I just built an app on my phone with no internet and no console.log, like a medieval JavaScript peasant. Who’s joining my coding Amish community? 👨🏻‍🌾

The $0MRR founder breakfast

Me waiting for my business metrics to magically improve

Alright, I guess that's enough coding for today.

Sorry, can’t jump on a call. I’m busy horizontally scaling.

Sunday coding session. Step 1: Open laptop. Step 2: Take photo. Step 3: Close laptop. Step 4: Tweet about the grind.

Cursor is great and all, but have you tried Cat-sor? It physically prevents you from introducing bugs. One treat per prompt. Premium starts at tuna 🎣

Built an app on my phone on a flight to Istanbul. No internet. No ChatGPT. No Google. No DevTools. Every bug had to be solved using the ancient art of... thinking.

If aliens landed last night… They’d assume honking is how humans reproduce. You haven’t really experienced Spain until someone’s celebrated a football trophy directly under your bedroom window. My sleep schedule lost 7-0.

That’s the reason I’ve developed this really useful skill:

Coding from Popeyes because my startup can't afford an office... ...or groceries. Nothing says "bootstrapped founder" like deploying to production with chicken grease on your keyboard.

Do you know that HTML has a <legend> tag? Coincidentally, that's also how I introduce myself after fixing one CSS bug 😎

Don’t think I’ve ever seen anything cooler than this site: lusion.co Probably AI slop though 😅

You have more cool equipment than David Guetta

I'm about to weaponize Relume and Claude Design to answer one question: Can AI produce a website that doesn't immediately look AI-designed? Enough purple gradients. Enough floating glass cards. Enough of the same smiling people pointing at analytics.

Here are the secret facts about me. Drop yours below if you're willing to accept the consequences. And yes, this entire thing runs on React. Some people call it overengineering. I call it having standards and mild psychological problems. sergeytkachenko-cj.github.io/secret-facts...

There are two stages of becoming a CSS developer. Stage 1: “I am a CSS god.” Stage 2: “Cursor has reviewed my code.” The scrollbar became a progress bar 😅

Spent nearly 3 days making a website responsive for a screen size nobody has ever opened a browser on. So what's the smallest device you've written a media query for? Smart watch? Tamagotchi that somehow has a browser in 2026? The display on an insulin pump?

I finished The Singularity Is Nearer by Ray Kurzweil. I came away thinking, "I really hope I stay alive long enough to see all this tech stuff." Definitely wearing a helmet every time I ride my bike now 😅

Working from the beach sounds glamorous until you’re staring at a stack trace while sunscreen drips into your keyboard. And undefined is still not a function, but now outdoors.

Startup idea: A tiny box of real grass for your desk. Whenever someone tells you to “touch grass”, you can calmly place your hand on it and continue arguing online. Current valuation: $47 million.

Today I added special handling for screens below 380px. If your device is any smaller, please stop browsing and return it to the museum immediately.

Front-end developers are good at respecting boundaries. Because front-end development is mostly about forcing boxes to respect each other's boundaries. A valuable life skill, honestly. And that's exactly what I did all day today.

Responsive design never really stops. You spend 5 hours making the app work on every screen size. Then some good man opens it on a Samsung Smart Fridge and gives you a one-star review.

Today's coding session: hide things on mobile. That's it. That's the feature. Weeks of development just to conclude that users shouldn't see half of it. At this rate, my mobile version will soon be a blank page with excellent performance.

Today's coding session: Responsive layout refinement. Which is developer-speak for: "Move stuff around by 3 pixels for 6 consecutive hours” Now my app now works perfectly on exactly one device - my laptop 😅
