Real-world engineering challenges I solved while building modern web applications.
IMemoryCache can boost API performance by 3-5x, but misconfiguration causes memory leaks and stale data. Learn production-tested patterns for safe caching, including token-based invalidation, size limits, and when to choose Redis instead.
After migrating 12 monolithic .NET applications to microservices, here are the patterns that actually work: Kafka event streaming, Saga orchestration, Kubernetes deployment strategies, and the mistakes that caused production outages.
IMemoryCache isn't enough for scaled .NET applications. Learn how to implement Redis distributed caching safely: preventing cache stampedes, optimizing serialization, handling connection drops, and tuning for production Kubernetes environments.
Jetpack Compose and Kotlin are the standard, but building production-ready Android apps requires more than basic tutorials. Learn the real-world patterns for state management, avoiding recomposition traps, optimizing Room, and structuring scalable Clean Architecture.
Beyond basic tutorials: Learn how to build scalable, crash-free iOS apps using type-safe NavigationStack routing, the new @Observable macro, and robust MVVM patterns that handle complex state changes.
Textbook cryptography rarely survives contact with production. Learn how to properly implement public/private key encryption, master Envelope Encryption, secure your keys in KMS/Vault, and understand modern TLS and Post-Quantum Cryptography.
Building Azure AI applications is easy. Building them for production at scale is hard. Learn the real-world patterns for RAG architecture, token cost optimization, prompt injection defense, and monitoring that we use to run Azure OpenAI workloads serving 10M+ requests monthly.
Moving from VMs to Kubernetes is complex. This guide covers the practical reality of orchestrating microservices: managing Deployments, configuring Services, implementing autoscaling, and avoiding common production pitfalls that crash clusters.
EF Core is powerful, but misconfigured queries can crash your database. Learn production-tested patterns for avoiding N+1 queries, mastering AsSplitQuery, implementing keyset pagination, and preventing change tracker memory leaks.
Learn how to test ASP.NET Core Web APIs using xUnit, including unit testing controllers and services, integration testing with WebApplicationFactory, mocking dependencies, database testing, authentication scenarios, and production testing strategies.
Learn how to integrate Alibaba Cloud AI models into modern applications using Qwen models, API services, Retrieval-Augmented Generation, vector databases, AI agents, and enterprise AI architecture patterns.
Learn how to optimize PostgreSQL database performance using indexes, query analysis, execution plans, indexing strategies, and production optimization techniques for high-performance applications.
Learn how to improve Entity Framework Core performance using efficient LINQ queries, tracking optimization, projections, indexing strategies, compiled queries, database optimization, and production-ready techniques.
Learn the most important .NET design patterns with practical C# examples. Understand SOLID principles, creational, structural, and behavioral patterns used to build scalable and maintainable enterprise applications.
Learn how to apply SOLID principles in .NET applications with practical C# examples. Understand Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion principles for building maintainable software.
Learn how to apply Domain Driven Design (DDD) in .NET applications. Understand entities, value objects, aggregates, domain events, bounded contexts, and enterprise architecture patterns with practical C# examples.
Learn Jetpack Compose from beginner to advanced concepts. Understand composable functions, state management, layouts, navigation, Material 3, animations, performance optimization, and modern Android UI architecture with Kotlin examples.
Learn Kotlin Coroutines and Flow for modern Android development. Understand suspend functions, coroutine scopes, dispatchers, StateFlow, SharedFlow, error handling, and reactive programming with practical examples.
Learn how to build scalable Android applications using Clean Architecture with Kotlin. Understand layers, dependency rules, MVVM, use cases, repositories, dependency injection, testing, and modern Android development practices.
Learn how to use the Combine framework with SwiftUI to build reactive iOS applications. Understand publishers, subscribers, operators, @Published, ObservableObject, asynchronous streams, networking, and best practices.
Learn SwiftUI state management from beginner to advanced concepts. Understand @State, @Binding, @StateObject, @ObservedObject, @Environment, ObservableObject, @Published, and the modern Observation framework for building scalable iOS applications.
