Build Real Skills.
Structured guides on web development, DevOps, backend, system design, AI/ML, and AR/VR — with real code examples.
Tech Categories
Java
From basics to expert: OOP, Collections, Streams, Concurrency, Spring Boot REST APIs, System Design, Error Handling, Performance Optimization, and Database Indexing.
Web Development
HTML, CSS, JavaScript, TypeScript, frameworks like React and Vue, and modern web APIs.
Vue Masterclasses
Step-by-step, module-by-module masterclasses covering Vue 2 (Options API, Vuex, Vue Router v3) and Vue 3 with TypeScript (Composition API, Proxy reactivity, Pinia, RBAC routing).
React Masterclasses
Deep, module-by-module masterclasses on React internals and enterprise architecture — Class Components and the full lifecycle, React + TypeScript + Redux Toolkit, and dedicated performance optimization patterns.
Angular Masterclasses
Module-by-module masterclasses on enterprise Angular — NgModule vs Standalone architecture, strict TypeScript component design, Hierarchical Dependency Injection, RxJS and Signals, and typed routing with guards.
JavaScript Deep Dive
An exhaustive, engine-level JavaScript masterclass — memory and type coercion mechanics, the prototype chain and `this` binding, the event loop and Promise internals, V8 JIT optimization and garbage collection, and expert design patterns with Proxies.
DevOps
CI/CD pipelines, Docker, Kubernetes, infrastructure as code, and cloud deployments.
Backend & Servers
REST APIs, databases, authentication, caching, message queues, and server-side patterns.
System Design
Scalability, distributed systems, load balancing, CAP theorem, and architectural patterns.
AI & Machine Learning
Neural networks, supervised learning, NLP, computer vision, and ML engineering.
AR / VR
Augmented and virtual reality development with WebXR, Unity, and spatial computing.
