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
A practical look at using tower as the middleware layer for Rust AWS Lambda functions, with examples that build up to a DynamoDB-backed per-IP rate limiter. It covers Service, Layer, stack ordering, short-circuiting, boxed async futures, and testing middleware without deploying a Lambda. Comments
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

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
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
A hands-on dev review focused on i18n, date/number formatting, and non-ASCII edge cases. Why I Tested TestSprite for Locale Handling Specifically Most AI testing tools get reviewed for their core functionality — does it find bugs, does it write good test code, does it integrate with CI/CD. Those reviews exist. What I couldn't find was a focused review on how TestSprite handles locale-specific edge
