Self-Healing Webhook Bridges: Syncing Third-Party Vendor Data into Custom Portals Without Loss
Webhooks are at-least-once, unordered and best-effort. Build a durable inbox, version-guarded processor and reconciliation loop that keeps your custom portal converged with vendor data even when deliveries fail.
Ephemeral Pull-Request Preview Environments with Kubernetes and GitOps
Eliminate staging bottlenecks and configuration drift. Architect production-grade ephemeral pull-request preview environments using Kubernetes namespaces, ArgoCD ApplicationSets, Let's Encrypt wildcard TLS, and copy-on-write database branching.
