Aether SDK

The Problem

Every integration project rebuilds the same plumbing: entity models, sync loops, webhook handling, secret management, and tenant separation — rewritten per tool, per client, per project. The plumbing is never the product, but it's always the risk.

Aether SDK is a universal, multi-tenant sync and orchestration substrate: one entity model, one adapter interface, and tenancy enforced from core to storage — so connecting a new system means writing an adapter, not an application.

Architecture

Engineering Discipline

• Tenancy as an invariant, not a convention: every entity, storage call, adapter push, secret lookup, and webhook event carries a TenantId enforced from core to backend — adapters cannot write into another tenant's slice.
• CI that blocks on isolation: a dedicated tenant-isolation end-to-end test suite runs as a required merge gate. A red mark blocks the merge.
• Tier-aware feature management: adapter access controlled across free / pro / enterprise tiers from a single flag manager.
• Single-tenant stays simple: deployments that don't need tenancy run unchanged under a stable default tenant.

Why It Matters Here

This is the systemized version of the integration work in my track record — the Docebo/Workday/Salesforce/SSO wiring done at Entrust and FHLBC, generalized into infrastructure that makes the next integration a config exercise instead of a rebuild.
