In 2015, I had an interesting task: build a crossword game. The UI was easy. The hard part was the grid: fit 20 words so every crossing shares a letter. I ran my old Swift generator again. 11 years later, I found a word it can never place 👇 #gamedev #iOSDev #Swift

How it works: 1. Sort the words, longest first 2. Try every spot where the next word shares a letter with the grid (red = doesn't fit) 3. Score each spot by its crossings; take the best 4. Repeat 30 times; keep the grid with the most words Code: github.com/maximbilan/iOS-Cr…

The word is SYNCOPATION, from my own README. It's always 2nd in line, and the 1st word always lands on the 2nd row, so SYNCOPATION can only cross it with S or Y. PUMPERNICKEL has neither. I'm bringing my old code back to life, one post at a time. Follow for the next one.

Yesterday: the 3D Pac-Man that got me my first game dev job. But it wasn't enough. Gameloft sent an "additional test". Cars, Bullet physics, burning barrels. C++, 2011. Here it is on my Mac, 15 years later. They hired me anyway. Show me your first test task 👇

This 3D Pac-Man got me my first game dev job. Gameloft test task, 2011. C++, Irrlicht, Visual C++ 2008. 15 years later I rebuilt it on my Mac and found a bug: the snow I listed under "additional features" has alpha 0. Invisible the whole time ❄️ What was your first test task? #BuildInPublic

What if we had Claude Code for Windows 3.1? 🔊 Dial-up to the model. Models on 7 floppies. "Not enough memory to start Subagent 4." And it still finds a clever way to save 2 bytes.

My first programming language was QuickBASIC on MS-DOS. The coolest thing I made back then: green Matrix rain in the terminal. So I rebuilt it in Go with Claude for 2026 👇 What was YOUR first programming language? Drop it below; let's connect 🤝

Parents abroad: how do you keep up with school chats in a language you're still learning? I built a bot for it: 47 Spanish messages → 1 Ukrainian digest, every evening. Right now it's just for me. Should I keep going and turn it into a real product?

Something I built at the start of the year and never shared. I wanted Grammarly in my terminal, running on my own OpenAI or Claude key. So I made grammr. Would you use this? Worth working on, or should it stay a personal tool? #BuildInPublic

Сouchmode 🛋️ 📺 is submitted to the Amazon hackathon, a week before the deadline. The agent runs on your laptop; the TV shows its work; you approve from the couch. Open source 💾 #BuildInPublic

Saw the flying @Tesla Roadster. Gave it a go on lap one 🚀 Rocket pack not in the game. The flying laps are. #BuildInPublic

Cut the price of my game in half. Next day: one sale. From the UK 🇬🇧 Statistically meaningless. Emotionally huge 😅 Indie devs: Has lowering the price ever actually moved the numbers for you? #BuildInPublic

Didn’t win #Shipaton 🏁 No regrets. When I started, this account had 36 followers. Today it’s 245, and more importantly, I met some genuinely great people along the way. Shipped a game, a browser build, and a watch build nobody asked for. Learned more about building in public than in years of not doing it. Thanks @RevenueCat for running it, and congrats to the winners 🎉 I make small weird things. Let’s connect 👋 #BuildInPublic
