Scaling from 10 users to 10 million — the decisions that matter at each stage
Scaling isn't one problem. It's a sequence of different problems that appear at different stages. Here's what actually matters at 10 users, 10,000 users, 100,000 users, and 10 million — and the mistakes that come from solving tomorrow's problem today.

AI observability — logs, traces, cost and hallucinations
You can't run an LLM system on hope. Traditional observability misses the things that actually go wrong with AI: silent quality drift, runaway token cost, and confident wrong answers. Here's the observability stack an AI system needs.

AI rate limiting and cost control — before the bill surprises you
One buggy loop or abusive user can turn an LLM feature into a five-figure invoice overnight. Rate limiting and cost control for AI aren't the same as for a normal API — here's how to cap spend without breaking the product.

Domain-Driven Design for startups — the parts worth keeping, the parts worth skipping
DDD is a powerful set of ideas buried under a lot of enterprise ceremony. Here's what's genuinely useful for a startup — bounded contexts, ubiquitous language, aggregates — and what you can safely skip until you need it.

Hexagonal Architecture without overengineering — ports, adapters and the line you shouldn't cross
Hexagonal Architecture is one of the most useful ideas in software design. It's also one of the most over-applied. Here's what the ports-and-adapters model actually buys you, where it becomes ceremony, and how to apply it without drowning in abstractions.
