SaaS Architecture.

Scale without rewrites.

Multi-tenant data, auth, billing, infra. Systems designed to hold up at scale — and not require a re-architecture every six months.

What you get

Capabilities, not buzzwords.

Multi-tenant Postgres
Row-level security, schema-per-tenant, partitioning. Pick the right one and I'll explain why.
Auth + RBAC
SSO, SCIM, audit logs, fine-grained permissions. Enterprise-ready without an enterprise-sized team.
Billing on Stripe
Subscriptions, usage metering, invoicing, dunning, sales-led pricing. Done so finance stops asking.
Jobs, queues, schedulers
Idempotent workers, retries, observability. Background work that doesn't quietly fail.
Observability
Logs, metrics, traces, error tracking. PostHog, Datadog, Sentry — wired to the right alerts, not all of them.
Deploy + CI/CD
Preview envs per PR, fast main-branch deploys, rollback in one click.
