KEDA changes the conversation — scaling on Kafka lag, SQS depth, or Redis list length is way more useful than CPU for any async workload. The scaleTargetRef + minReplicaCount: 0 combo lets you drop worker pods to zero during idle, which single-handedly cuts the bill on BullMQ-style queues.

Day 12: Kubernetes Autoscaling Design. "How does your k8s cluster scale?" → Most candidates say HPA. Interviewers want all 3 layers. Layer 1: HPA (Horizontal Pod Autoscaler) → Scale pod replicas based on CPU/memory or custom metrics → Custom metrics: Prometheus Adapter → KEDA (event-driven) → Stabilization window matters — prevent flapping Layer 2: VPA (Vertical Pod Autoscaler) → Right-size pod resource requests/limits automatically → Don't run VPA + HPA on same metric simultaneously Layer 3: Cluster Autoscaler / Karpenter → Add/remove nodes based on pending pods → Karpenter (AWS) → provisions nodes in seconds vs minutes → Spot instance handling: interruption detection + graceful drain Interview signal: "We use KEDA for queue-based scaling — scale to zero when queues are empty." Cost optimization + scale-to-zero = senior flag.

For "charge a card" the answer most candidates miss is the ledger is the source of truth, not the payment gateway — append-only entries with double-entry accounting invariants, then reconcile the gateway state against it via a scheduled sweep job. That framing also solves the webhook out-of-order problem.

14/ Company‑specific: Razorpay / Stripe / fintech Key themes: - Consistency, correctness, idempotency - Observability: logs, metrics, alerts - Security mindset Prep: - Know exactly how you’d design “charge a card”, “retry a failed payment”, “webhook with retries + backoff.” - Have real examples of bugs you prevented / debugged in critical flows.

Unique index on event.id + INSERT first, then catch 23505 and 200 → gives you dedup for free. For out-of-order the trick is reading subscription.status from a Retrieve API call inside the handler rather than trusting the event payload — Stripe has eventual consistency on the object but the API is canonical.

@kayintveen @fidexcode stripe webhooks specifically yeah. spent more time on webhook idempotency than the actual checkout flow. events show up out of order, duplicates fire randomly — claude gives you a clean handler that works great until real traffic hits it
