Software Architecture & Performance

Designing software that scales, responds, and performs

Architecture decisions that create lasting value

Good software architecture is not only about choosing patterns or technologies. It is about understanding how boundaries, data structures, state management, and implementation choices influence a system as it grows. The course explores approaches such as modular front ends, unidirectional data flow, branded types, and well chosen data structures and shows how they can reduce coupling, prevent subtle errors, and make complex applications easier to understand and maintain. You will also learn how to evaluate architectural trade offs instead of introducing complexity simply because a technology or pattern is available.

Performance from architecture to runtime

Performance needs to be considered across the entire system, from SSR and hydration in the browser to CPU usage, task scheduling, data structures, and application architecture. The course combines practical examples with real world measurements to show how architectural decisions can affect responsiveness, scalability, and resource consumption. You will explore how to identify bottlenecks, choose efficient approaches, benchmark implementations, and validate performance improvements, while also learning where AI assisted development and agent oriented architectures can introduce new opportunities or unexpected costs.

Take Your Skills to The Next Level

Article | Deconstructing the Monolith: Architecting Loosely Coupled Front-Ends with the Mediator, Façade, and Module Patterns | Gil Fink

Explore the Module, Façade, and Mediator patterns and learn how they can decouple complex front ends, improve testability, and make large JavaScript applications easier to maintain.

Article | Taming UI State: Engineering Predictable Unidirectional Data Flows | Gil Fink

Understand Flux and unidirectional data flow and how predictable state management helps eliminate cascading updates and makes complex applications easier to debug.

Article | Hydration is not free: The hidden costs behind SSR performance | Soumaya Erradi

Learn how server side rendering and hydration affect performance, interactivity, data transfer, and application complexity, and why SSR always involves architectural trade offs.

Article | Branded Types in Production: The Architecture of Domain Integrity | Soumaya Erradi

Discover how Branded Types in TypeScript create stronger domain boundaries and prevent subtle bugs caused by structurally identical values crossing semantic boundaries.

Article | A Survey of Data Structures | Michael Dowden

Build a practical toolbox of TypeScript data structures, including arrays, records, stacks, queues, linked lists, trees, and graphs, and learn how they affect performance, memory usage, and maintainability.

Session | Beyond Microservices: Migrating from Service-Oriented to Agent-Oriented Architecture | Andrew Miller

Compare service oriented and agent oriented architectures, explore migration strategies, and understand the trade offs around flexibility, reliability, orchestration, monitoring, and governance.

Session | Six Languages, One AI: What Real-World Performance Teaches Us About Choosing the Right Stack | Bohuslav Šimek

Examine an AI assisted development experiment across PHP, Python, JavaScript, Ruby, Rust, and Java, comparing runtime performance, developer experience, iteration speed, and end user performance.

Session | Mastering Task Management in JavaScript | Gil Fink

Learn how browser task scheduling can improve responsiveness by deferring non urgent work and allowing the browser to prioritize user interactions.

Session | Where We're Going, We Don't Need Mockups: Instant Prototyping with Agentic AI | Laurie Lay

See how agentic AI can accelerate full stack prototyping by generating APIs, database schemas, and React front ends, turning business ideas into testable proof of concepts in hours.

Session | How I Made Immer Twice as Fast: Performance Optimization in Practice | Mark Erikson

Explore performance optimization in practice and learn from a real world case of improving the performance of Immer.
