Architecture & System Design Challenges
Architecture & System Design challenges put you inside the work of shaping how large software systems fit together. You'll build skills in systems design fundamentals, architecture diagrams, and the C4 model, capturing decisions in Architecture Decision Records (ADRs) the way engineering teams keep their reasoning legible.
From there you'll take on the harder edges — distributed systems design, event-driven architecture, and microservices patterns — driving alignment through RFC authorship and cross-team architecture stewardship while keeping developer experience front of mind. Each challenge you solve earns a verified credential you can share with recruiters.
