I kept watching the same thing happen. What I Built It's a 3D interactive sales simulator. I call it a flight simulator for software — except instead of flying a plane, you're walking a non-technical client through the risk inside their own infrastructure. The Map You feed it a simple JSON file describing your client's tech stack. It reads it and instantly draws a floating, 3D web of nodes — s
I was building a side project that needed image compression. My first instinct was to look for an API — TinyPNG, Cloudinary, something with a POST endpoint. if (blob.size >= file.size) { Try the requested quality first. If the output is bigger, walk down through lower qualities until something sticks. As a last resort, if WebP output is still larger, fall back to JPEG entirely. Not elegant, but it
Ever had users sign up with [email protected] or [email protected]? Disposable email addresses are a headache for any app that relies on real user contact. I built burner-bouncer to solve this — a zero-dependency libra
I finished an English series on the way I think ordinary people can start using AI for real work. The point is not to become an AI expert first. The point is to have one place where you can say what you want, give the tool access to the right folder, and check the result. Anything important still needs a human pause: publishing, deleting, paying, or authorizing. My preferred starting point is simp
When you bind Ctrl+S to "save" in a web app, do you check event.key === "s" or event.code === "KeyS"? The honest answer is "I don't remember, I copy-paste from Stack Overflow." Until a Dvorak user reports the shortcut is broken — or a Japanese IME user reports it fires mid-composition. This is a live inspector for KeyboardEvent: press any key (or combination), see every field — key, code, keyCode,
Imagine you have a Nodejs server with endpoint that performs heavy CPU operations. By default your server runs on a single thread. This means it will freeze depending on the CPU load. If your server has other asynchronous endpoints, for example, to execute database operations, those endpoints would become unresponsive while the heavy load endpoint is processing. Our first idea is to create more th
Every dev team has lost hours to .env problems. A missing variable breaks a deploy. I built Razify to make all of that stop happening. Razify is a single binary CLI tool for .env file management. No cloud account No tracking No Go installation required Works with Node.js, Python, Ruby, Laravel, Rails — anything that uses .env files. razify scan .env Detects leaked secrets using 80+ regex patte
I got tired of not knowing why users were dropping off in my app. Heatmaps show you where people click. Analytics show you when they leave. But nothing tells you how they felt while using it. So I built SessionMood API — a REST API that scores user mood in real time based on behavioral events. You send behavioral events from your frontend: fetch("https://session-mood-api-production.up.railway.app/
