How does this skill help with architecture diagrams?

It uses the C4 model framework to help you define System Context, Container, and Component diagrams within your technical documentation using standardized notation.

Can it estimate cloud infrastructure costs?

Yes, it provides a structured approach to capacity planning, calculating server, database, and CDN requirements based on expected user traffic and data throughput.

Does it support Architecture Decision Records (ADRs)?

Absolutely; the skill emphasizes documenting the rationale behind design choices, helping teams maintain a clear history of architectural trade-offs and decisions.

Is this skill useful for technical interview preparation?

Yes, the skill follows industry-standard patterns and best practices used in high-level system design interviews at major technology companies.

API Development

Architects scalable, production-ready systems using C4 modeling, capacity planning, and rigorous trade-off analysis.

About

The System Design skill empowers developers and architects to build robust, enterprise-grade applications by providing structured frameworks for architecture visualization and decision-making. It guides users through the C4 model for multi-level diagramming, assists in detailed capacity planning—including traffic, storage, and cloud cost estimations—and facilitates objective trade-off analysis for critical technology choices. Whether you are refactoring a monolith or designing a high-traffic distributed system, this skill ensures best practices like loose coupling and fault tolerance are integrated into your development workflow.
