Architecture, resilience & cost
Deep notes on building resilient, event-driven distributed systems and the trade-offs (and cost) nobody mentions until production.

How Graceful Degradation Reduces Cloud Costs
Resilience is usually sold as an availability feature. It's also a cost lever, and a big one. A system that degrades under load doesn't need to be provisioned for its worst moment, which means you stop paying, 24/7, for capacity you use twice a year.

Circuit Breakers in Node.js: When Slow Dependencies Become System Failures
A dependency doesn't have to be down to take your service with it. A slow one is worse. Here's how a circuit breaker works, how to build a correct one in Node.js and TypeScript, and the nuances that decide whether it protects you or just hides the problem.

Designing Read-Only Modes Without Breaking UX
Flipping a system to read-only is the easy 20%. The hard part is the UX: a naive read-only mode either lies to the user or buries them in error modals. Here's how to make degraded write paths feel like a deliberate product state instead of a broken one.

Graceful Degradation: Keeping Products Alive When Infrastructure Fails
Availability isn't binary. Senior systems degrade instead of dying. Six patterns to keep the product usable when the backend, the database, or a third-party API goes down and why they let you run leaner infrastructure.
