Why This Topic Matters OTP (One-Time Password) verification is a critical security feature in modern mobile applications. Whether you're building a fintech app, healthcare platform, or any service requiring user authentication, implementing OTP verification efficiently can be the difference between a smooth user experience and frustrated users abandoning your app. The react-native-otp-auto-verif
How intentional loading decisions keep your app fast at scale. Frontend performance is not a late-stage cleanup task. It’s not tech debt. It’s a set of decisions we make every day while we code — what we load, when we load it, and how we render it. The answer depends on the importance of the code, its size, and when the user actually needs it. Get that wrong, and the browser pays for everything
Introduction Building a mobile application that handles sensitive financial data — crypto transactions, KYC verification, gift cards — means security is not an afterthought. It is a core deliverable. During the development of a cross-platform fintech application, one of the non-negotiables on the security checklist was runtime application self-protection (RASP). After evaluating our options, we
I’m going on a short vacation this week, so this post is coming out a bit earlier than usual. I actually had a different, more “useful” topic in mind — something educational, something responsible. But then I came across this fascinating article: I don’t like Tailwind. Sorry not sorry written by @freshcaffeine , and I couldn’t get it out of my head. So I decided to write a response instead. I actu
What Is an Atomic Transaction? Before we begin, let’s define atomic transaction clearly: “It is a protective wrapper around multiple state updates that guarantees the whole operation either succeeds completely or has no effect at all.” Inside an atomic transaction, you can perform multiple set() calls, and even cross multiple await boundaries. Only when the entire operation succeeds do we commit
React Native's New Architecture — JSI, Fabric, and TurboModules — has been "coming soon" for long enough that some teams wrote it off as vaporware. It shipped. It is now default in new React Native projects. And it meaningfully changes how the framework works at the performance-critical boundaries between JavaScript and native code. This post is not a getting-started guide. It is an honest account
The "Unsharable" Dashboard Problem Imagine this common B2B SaaS scenario: An executive opens your analytics dashboard. They spend three minutes configuring the data—they filter the status to "Active," set the date range to "Last 30 Days," sort the table by "Highest Revenue," and navigate to Page 4. They copy the URL and Slack it to their team lead. The team lead clicks the link, but instead of see
It's a one-line item on the roadmap. "Send a push notification when X happens." Estimate is two days, three if the backend doesn't have FCM credentials yet. There's a library for it. The library is the visible part. The other 90% is platform lifecycle, registration state machines, race conditions with navigation, payload archaeology, and a half-dozen iOS and Android quirks. Nobody writes them down
