Read article →Questions Sujith gets asked
When does Sujith recommend reactive programming over a traditional REST stack?
Reactive shines when you have high-fan-out workloads, websocket-heavy products, or systems that must hold steady under unpredictable traffic spikes. For a CRUD admin tool, classic REST is still the right tool.
How does Kiebot’s engineering org keep code quality high while moving fast?
Three non-negotiables: every PR is reviewed by a senior, CI runs the same checks that block production, and we treat tests as part of the deliverable, not an afterthought.
