KanmonOS

Embedded lending platform powering term loans, lines of credit & invoice financing for vertical SaaS

Jan 2025 — Nov 2025
  • Contributed to Kanmon (kanmon.com) — an embedded lending infrastructure that lets vertical SaaS platforms (professional services, practice management, digital supply chain, and industry-specific business management software) offer term loans, lines of credit, and invoice/trade financing to their SMB customers without leaving the host platform.
  • Worked across backend and frontend on the customer onboarding and lending lifecycle: queue management, Persona-based KYC/identity verification, Astra payment processing, and state-machine logic driving application, underwriting, disbursement, and repayment stages.
  • Helped keep the platform compliant and low-risk for partners by implementing well-bounded modules, idempotent workflows, and predictable state transitions across the embedded lending flow.
