Built a copy-paste utility in Flutter. Started with 1 feature. Ended with 11. Learned more in one weekend than months of tutorials. Edge cases are where the real learning happens. GitHub link: github.com/Pinkisingh13/Util… #Flutter #Android #Ios #WebApp #OpenSource

My most powerful productivity tool doesn't have a battery. I spend 10 hours a day in VS Code. But I realized digital tools are great for speed, yet terrible for clarity. Notifications kill deep work. "Undo" buttons kill commitment. So for 2026, I went back to basics. 📝👇

Why paper? Because you can’t "backspace" ink. Digital planners let you archive goals when they get uncomfortable. A physical notebook stares you in the face. You have to own it. Sometimes, to move forward in tech, you have to disconnect from it. Team Paper or Team Digital?

I reverse-engineered my own Flutter app using free tools. If I can hack my own app this easily, so can anyone else. Full guide on what I found and how to protect your apps: medium.com/p/0abc0ce0beaa #Flutter #AppSecurity #MobileDev #CyberSecurity #DevTips

I reduced my #API latency from 2.2s → 1.0s without spending a dollar. I’m building VeloxFi (#CryptoTracker) with #NodeJS & #Flutter. I didn't want a faster server, so I wrote faster code. 🌟GitHub Code: github.com/Pinkisingh13/Velo… #buildinpublic #backend #100DaysOfCode #flutter

Users judge your app in <3 seconds. I recently fixed a slow IoT startup flow: Wrong: sequential: await a; await b; (4s wait) Parallel: Future.wait([a,b]); (1.5s wait) Small change. Huge impact. Full breakdown 👇 linkedin.com/feed/update/urn… #Flutter #IoT #MobileDev #Performance
