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.
Green CI pipelines can still hide production bugs. Learn how to build a robust, fast, and reliable testing strategy for ASP.NET Core using xUnit, Testcontainers, WebApplicationFactory, and modern .NET 8+ patterns that actually catch real-world failures.
Calling an LLM API is easy. Building a scalable, secure, and cost-effective AI application on Alibaba Cloud is hard. Learn production-tested patterns for Qwen models, AnalyticDB vector search, semantic caching, and VPC isolation.
Slow queries don't just annoy users; they crash production databases. Learn production-tested PostgreSQL optimization patterns: mastering EXPLAIN (ANALYZE, BUFFERS), covering indexes, BRIN for time-series, and tuning autovacuum for high-churn tables.
EF Core is powerful, but misconfigured queries can silently crash your database. Learn production-tested patterns for mastering AsNoTracking, solving N+1 queries, implementing Keyset Pagination, and preventing Change Tracker memory leaks.
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.
Moving beyond basic tutorials: Learn how to build robust, leak-free Android apps using Kotlin Coroutines and Flow. Master structured concurrency, lifecycle-aware Compose collection, StateFlow vs SharedFlow, and production-ready testing patterns.
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.
