Explore the mathematical foundations of spectral methods in machine learning. Understand how eigenvalues, eigenvectors, and spectral decompositions underpin dimensionality reduction, graph learning, and kernel methods, with a focus on theory and structure.

Dive deep into the internal workings of Spring AOP. This course is designed for Java and Spring developers who want to understand not just how to use AOP, but how it operates under the hood. Explore the architecture, proxy mechanisms, weaving, and the lifecycle of advice in Spring AOP, with a blend of theory and hands-on code exploration.

A beginner-friendly course introducing the core concepts and practical skills for testing Spring Boot applications. Learn unit testing, integration testing, test slices, mocking, and effective testing strategies to ensure robust and maintainable Spring projects.

Manage application state in React using Zustand. Create and update stores, derive and organize state, handle asynchronous logic, and apply middleware for extended behavior. Structure Zustand stores effectively and evaluate when Zustand is an appropriate state management solution.

Explore the mathematical foundations of machine learning generalization. This course covers empirical risk minimization, bias–variance tradeoff, VC dimension, generalization bounds, and the theory of overfitting, equipping you with rigorous intuition for model selection and evaluation.

TLS and HTTPS Internals is a course for developers, DevOps engineers, and anyone who wants to understand what’s actually happening behind the little lock icon in the browser’s address bar. No academic jargon, no 400-page RFCs, and no boring textbook diagrams. Instead, you’ll see the story of paypa1.com with a green lock, Maria sitting in a café using open HTTP, and DigiNotar collapsing within a month after being hacked. If you’re tired of googling “what is a cipher suite” every time something breaks — this course is for you.

Manage server state in React applications using TanStack Query. Fetch, cache, and synchronize remote data, handle mutations and optimistic updates, and implement advanced query patterns for dynamic data flows. Optimize queries for performance, scalability, and maintainability in production React applications.

Test React applications using Jest and React Testing Library. Write unit and integration tests, validate component behavior through user interactions, and debug test failures effectively.

Learn to represent documents as high-dimensional vectors, apply TF-IDF weighting, measure document similarity, and discover structure in text collections using geometric and statistical modeling—without linguistic or NLP assumptions.

Build 3D graphics in React applications using Three.js. Create and render 3D scenes, add objects, lighting, and cameras, and implement interactive and animated behaviors. Optimize rendering performance and structure scalable 3D applications for production use.

A comprehensive course for software engineers and SRE/DevOps professionals on understanding, detecting, and mitigating traffic flooding events, and designing resilient systems to withstand such incidents.

A comprehensive, code-free exploration of transformer-based language models, focusing on their architecture, text generation mechanics, and the theoretical principles underlying their behavior.

Deepen your understanding of object-oriented programming with TypeScript by working with classes, encapsulation, interfaces, generics, and inheritance. Learn how to structure reusable components, enforce contracts, and design scalable class hierarchies.
