Real-world lessons from React Native, React, Next.js, NestJS and Node.js projects, with interactive system diagrams and code examples.
Moving from a monolithic backend to modular microservices: dependency injection, BullMQ queue management and fault-tolerant service design.
Building fluid mobile interfaces by relieving the JavaScript thread: the principles of Reanimated 3, Gesture Handler and TurboModules.
A multi-layer caching architecture that cuts database load by 80%: in-memory cache, Redis invalidation strategies and the Cache-Aside pattern.
Server Components, Client Components, Streaming SSR and Suspense: maximum speed on the web with a zero-JS client bundle.
An index architecture that brings queries down to milliseconds: the B-Tree structure, using EXPLAIN ANALYZE and composite index strategies.
Low latency in live location, chat and notification systems: the TCP 3-way handshake, the WebSocket upgrade and mobile battery optimization.
Smooth 60 FPS React Native apps with optimized render loops and native device capabilities for a seamless mobile experience.
Modular, testable and scalable microservice architectures with NestJS, including Redis caching and BullMQ asynchronous queue integration.
SEO-friendly modern web applications with fast load times (Lighthouse 99+), built on the Next.js App Router and SSR.
End-to-end type safety with TypeScript, Docker containerization and sustainable CI/CD pipelines.
