RarxNetwork
Umbrella SaaS network with shared identity, billing and infrastructure across multiple commercial products.
Designed and built the network-wide identity and billing layer so every product on the network shares one account, one Stripe customer and one usage dashboard.
Wrote the shared TypeScript SDK that each product imports — auth tokens, plan checks, feature flags, audit logs — so a feature can ship across the whole network in one PR.
Built the operations layer: status page, fraud watchlist for the billing flows, automated on-call alerting and a single observability pane.
All of it runs on a tightly tuned single-server stack (Nginx, PM2, Postgres) with zero-downtime deploys — instrumented and budgeted so the network is profitable from month one.
