Learn how to understand and troubleshoot API latency from a System Design perspective. This practical guide explains how network time, ASP.NET Core processing, database queries, and external API calls contribute to total response time, with a real latency breakdown and a simple ASP.NET Core timing example.

Understand how read-heavy and write-heavy workloads affect System Design. This practical guide explains read and write traffic, caching, read replicas, database performance, transactions, concurrency, and how a simple read/write traffic calculation can influence architecture decisions in .NET applications.

Learn how to estimate application traffic before designing a scalable system. This practical guide explains the difference between users, requests, concurrent users, average traffic, and peak traffic, with an e-commerce example and a simple C# calculation for estimating requests per second.

Learn how to identify users, roles, permissions, and use cases before designing APIs and architecture. This practical guide uses an e-commerce system to show how business requirements can be mapped from users and roles to use cases, features, and ASP.NET Core APIs.

Learn how real-world constraints such as budget, team size, existing systems, technology limitations, and delivery timelines influence System Design. This practical guide explains how .NET developers can balance business requirements with real-world limitations to create simpler, maintainable, and realistic software architectures.

Understand the difference between Functional and Non-Functional Requirements using a practical Order Management System example. Learn how the same feature can be viewed from two perspectives and how performance, security, availability, and scalability requirements influence ASP.NET Core system design.

Understand Non-Functional Requirements from a practical .NET developer's perspective. Learn how performance, availability, security, and scalability requirements influence ASP.NET Core APIs, database design, architecture, and real-world System Design decisions.

Learn what Functional Requirements really mean and how .NET developers can convert business requirements into users, actions, features, business operations, and APIs. This practical guide uses an Order Management System to explain how requirements become the foundation of effective System Design.

Learn how .NET developers can understand and break down software requirements before writing code. This practical guide explains how to identify the problem, users, system actions, use cases, business rules, data, and functional and non-functional requirements using a real-world Order Management System example.

Learn what System Design really means from a .NET developer's perspective. Understand how requirements, APIs, data, traffic, performance, availability, and scalability come together to build reliable real-world applications.

Understand the .NET GC's Mark, Sweep, Compact, and Finalization phases. Learn how it efficiently reclaims memory and keeps your C# apps running smoothly.

Unlock .NET performance secrets! Understand Garbage Collection generations (Gen 0, Gen 1, Gen 2) and how they optimize memory management in C#.

Learn how .NET's Garbage Collection automatically manages C# memory, preventing leaks and improving app reliability by reclaiming unused objects.

Secure your JWT-based ASP.NET Core API by implementing robust logout and refresh token revocation to prevent session hijacking and unauthorized access.

Enhance ASP.NET Core Web API security with JWT refresh tokens. Learn to implement long-lived refresh tokens for seamless user authentication and improved UX.

Integrate ASP.NET Core Identity roles into JWTs for seamless role-based authorization. Learn how to add role claims to your tokens.

Integrate ASP.NET Core Identity with JWT for secure user authentication, replacing manual password handling with robust, built-in features.

Replace hardcoded login with EF Core database authentication in ASP.NET Core Web API for secure user management and JWT generation.

Master custom authorization in ASP.NET Core. Implement complex business rules beyond roles/claims with custom handlers for enhanced security.

Master ASP.NET Core Policy-Based Authorization for complex business rules beyond roles. Learn to configure and apply policies for enhanced API security.

Learn how to implement role-based authorization in ASP.NET Core Web API using JWT. Secure your endpoints by assigning and verifying user roles.

Understand JWT claims in ASP.NET Core. Learn how claims identify users, how they're created, and accessed in controllers for efficient authentication.

Secure your ASP.NET Core Web APIs with the [Authorize] attribute. Learn to protect endpoints, differentiate public/private access, and prevent unauthorized data access.
