Start with the business rule
Real-time features, workers and picking the right tool.
Reliable software starts with understanding what must always be true. Write down the rule, identify the data it touches, and consider how concurrent requests could break it.
Keep the implementation explicit
- Validate inputs at the boundary.
- Keep related writes inside a transaction.
- Make failures visible and recoverable.
- Test the behaviour that matters to the business.
Measure what happens in production
A clear implementation is easier to monitor, explain and improve. Use real feedback to guide the next iteration.
