→ Tenant isolation is architectural, not policy-based.Row-level security at the database layer. Zero shared connection pools. Separate encryption keys per tenant. Cross-tenant data access is impossible by design — not prevented by an if-statement.
7UNIT / FINTECH
Financial systems built forregulated environments.
Fintech is not a harder version of normal software. It is a different problem entirely. The data is regulated. The workflows are audited. The failure modes have compliance consequences. We have built in this environment — and the architecture decisions we make reflect that.
7UNIT / WHAT WE HAVE BUILT
Financial operating systems that absorb multi-bank configuration, nightly batch submissions to lenders, commission operations, and document generation owned by operations — alongside multi-tenant stacks with RBAC enforcement, KYC and bureau integrations with async fallback handling, append-only audit trails, and compliance-aware data residency. Multi-tenant platforms where a tenant boundary failure is a regulatory event, not just a bug.
7UNIT / KEY ENGINEERING DECISIONS
→ Audit trails are append-only and immutable.Every state change writes a record with actor, action, before state, after state, timestamp, tenant ID, and request correlation ID. Non-deletable. Queryable for compliance reporting without touching production data.
→ KYC and bureau integrations are async with explicit fallback.Primary bureau with documented fallback provider. Applications are not blocked while checks run. Failed checks quarantine — they don't block the queue.
→ Compliance requirements are owned by your counsel, built by us.We implement the technical requirements your regulatory counsel defines. We do not hold PCI-DSS or RBI certifications. We are transparent about this boundary and will tell you in the first call whether our experience matches your compliance scope.
