Overview

LARK is a fintech lending platform that issues loans against securities. A borrower pledges their holdings, the platform values and underwrites them, and the funds are disbursed straight into their bank account.

It is the most complex system on this list. Money movement, pledged collateral and regulated borrower data all sit in the same flow, and none of them tolerate a partial failure.

Every state transition in the lending lifecycle is recorded, so the position of any loan can be reconstructed at any point in time — which is as much an operational requirement as a compliance one.

The engineering problem

Financial state can't be eventually consistent. Disbursal runs through idempotent, transactional service boundaries with an append-only audit log, so a retry never moves money twice and every position is reconstructable.

What it does

  • Loans issued against pledged securities
  • Disbursal directly to the borrower's bank account
  • Multi-step underwriting and approval workflows
  • Security and compliance treated as first-class requirements
  • Full audit trail across the lending lifecycle
