Your inventory management started in a spreadsheet. Now you're overselling, stock counts don't match reality, and warehouse picks take twice as long as they should. Here's how to build inventory systems that scale.
Your CEO doesn't want to hear about database migrations or refactoring sprints. They want to know if engineering is on track, what the risks are, and what you need from them. Here's how to communicate engineering progress to non-technical leaders.
Going multi-region sounds straightforward until you hit data replication, consistency trade-offs, and DNS routing. Here's the practical guide to deploying across regions without over-engineering it.
Event sourcing gives you a complete audit trail, temporal queries, and the ability to replay history. It also adds significant complexity. Here's an honest guide to when event sourcing is worth it and when CRUD is fine.

Kubernetes is the industry standard for container orchestration. It's also overkill for most teams. Here are simpler alternatives that handle containers in production without the operational tax.
Your API gateway starts as a simple reverse proxy. Then it becomes authentication, rate limiting, transformation, and orchestration. Here's how to design gateway architecture that scales with your platform.
Should you build your own A/B testing platform or use LaunchDarkly, Optimizely, or Statsig? The answer depends on your test volume, team size, and where experimentation fits in your engineering culture.

Your product page conversion rate is a function of performance, UX engineering, and trust signals. Here are the technical optimizations that consistently improve add-to-cart rates across DTC brands.
Everyone talks about logs, metrics, and traces. Nobody explains how to implement them so they're actually useful when your production system is on fire at 2 AM.
