#Architecture

Backends split into microservices, but frontends stay as one giant monolith. Micro frontends solve that — here's what they fix, how composition works, and when it's actually worth it.

As a single model grows complex, reads and writes start tripping each other up. Here's how CQRS solves that problem — from simple separation to full event sourcing, with TypeScript examples throughout.

Explore why synchronous request-response communication breaks down in microservices and how Event-Driven Architecture solves it. Covers Kafka vs RabbitMQ vs SQS, domain events vs integration events, event sourcing basics, eventual consistency, and practical Node.js examples.

Passing a function as props from a Server Component broke everything. Understanding the serialization boundary revealed RSC's true patterns.

Started with admin/user roles but requirements grew complex. When RBAC isn't enough, ABAC provides attribute-based fine-grained control.

I only used Redis as a cache until I discovered it handles sessions, leaderboards, pub/sub, and rate limiting. It's a Swiss Army knife.

10MB images upload fine but 2GB videos timeout. Chunked uploads, presigned URLs, and retry logic for robust file upload systems.

Sending one notification is easy. As notifications scale up, preventing duplicates, respecting preferences, and handling retries becomes a completely different engineering problem.

Started with SQL LIKE, hit its limits, moved to Elasticsearch, and got shocked by operational costs. The real trade-offs of search systems.

Integrating a payment API is just the beginning. Idempotency, refund flows, and double-charge prevention make payment systems genuinely hard.

1:1 chat is straightforward, but group chat, read receipts, and offline messages turn it into a completely different beast.

A URL shortener sounds trivial until you face hash collisions, expiration policies, and redirect latency. A microcosm of system design.

Component growing too large? Logic mixed with UI? Learn how to extract business logic into Custom Hooks for cleaner, testable code.

Main screen loads before user settings are ready? Compare 3 strategies: Awaiting in main(), Splash Screen, and AppLoadingWidget.

From simple CRUD to an append-only log of immutable events. We dissect Event Sourcing—the architecture behind scalable financial systems. Learn why it pairs perfectly with CQRS, how to handle the versioning of events (Schema Evolution), and the trade-offs involved in complexity versus auditability.

When our service grew, migrating from MongoDB to PostgreSQL became inevitable. But our code was a spaghetti mess of business logic and database queries. I share my journey of adopting Hexagonal Architecture (Ports and Adapters) to decouple the core logic from external tools, turning a nightmare migration into a manageable task.

Don't check every second if a new video is up. One subscribe button automatically notifies you. The elegant design pattern solving 1:N dependencies.

When Scale-Up fails, Scale-Out is the answer. Vertical vs Horizontal Partitioning, Shard Key selection strategies (Geo vs Hash), and the complexity of Distributed Transactions.

Singleton, Factory, Observer... Don't reinvent the wheel. Use the proven blueprints.

SRP, OCP, LSP, ISP, DIP. The foundation of maintainable software architecture. Examples in TypeScript.

MVC's Controller got too fat. Split into Presenter/ViewModel, auto-update with Data Binding. Core pattern of modern frontend.

When you break a monolith into microservices, you lose ACID transactions. How do you ensure data consistency across boundaries? We explore the limitations of Two-Phase Commit (2PC) and dive deep into the Saga Pattern, Event Consistency, and practical implementation strategies like Choreography vs Orchestration.

DDD is not just about entities and repositories. It's a strategic approach to tackling complex software problems. Learn how Ubiquitous Language, Bounded Contexts, and Aggregates can help you model the real world and align your software architecture with business goals. We also explore Event Storming and Strategic Design.

In complex domains, using a single data model for both reading and writing can lead to performance bottlenecks and messy code. Learn how CQRS (Command Query Responsibility Segregation) coupled with Event Sourcing can decouple your architecture, improve scalability, and simplify domain logic.

Context API is not a state management tool; it's a dependency injection mechanism. Understand why updating a single context value triggers widespread rerenders across your React app. We explore the 'Object Reference' problem, how to fix it with Split Contexts and Memoization, and when to abandon Context for dedicated state managers like Zustand or Redux.

Does 8 cores mean 8x faster? From Amdahl's Law to concurrency vs parallelism, hyper-threading, and why Chrome eats so much RAM.

Don't be fooled by spec sheet numbers. The real secret of CPU performance isn't how fast it ticks, but how much work it does per tick.

A CPU is actually a giant factory. Inside, there are Managers, Workers, and Workbenches.
