Here is what I learned after 50 interviews and fixing my resume after every rejection. The problem was never my skills. It was how I presented them. I wrote the same things most developers write. "Worked on the API." "Helped with database optimization." "Responsible for code reviews." Those sentences describe presence. They do not describe contribution. After months of getting ignored or rejected,
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,
Most developers like to believe that a good product will eventually speak for itself. Sometimes it does. More often, it quietly sits on the internet, perfectly engineered, carefully documented, and almost completely invisible. That is not because the product is bad. It is because the web is crowded. Search engines, communities, newsletters, blogs, GitHub repositories, comparison pages, and documen
When building modern applications, one problem shows up everywhere: How do I uniquely identify data across systems? That’s where UUIDs (Universally Unique Identifiers) come in. A UUID is a 128-bit unique identifier used to identify information in distributed systems. Example: 550e8400-e29b-41d4-a716-446655440000 It looks random - and that’s the point. Traditional IDs (like auto-increment integers
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/
There's a quiet shift happening in how AI tools interact with users, and most developers haven't noticed yet, because just one week after the MCP Apps specs were published by Anthropic, OpenAI launched a huge marketing campaign around OpenClaw and they got all the attention, at least for a while. For the past two years, every AI assistant has been stuck behind the same interface: a text box. You a
Thanks to AI, I've spent more time architecting and building apps, which means I spend a lot of time looking at frontier models and agonizing over token use. I’ve also been battling a very modern affliction: token consumption anxiety. It feels modern AI-powered app architecture is asking us slaps an LLM at the front door. You want to dynamically pick the best model for a specific task? Great, the
