📌 Digital Lending Journey – End-to-End (Text Only)

1. Customer Onboarding & Loan Request

• Amit R visits the Prestige Group website to book an apartment.

• He opts for a home loan and fills out the digital application form integrated with the bank’s lending portal.

• As Enterprise Architect, I ensured the onboarding microservices are designed to capture personal details, KYC documents, and consent, while integrating with Azure AD for authentication and data encryption standards for compliance.

2. Identity Verification & KYC

• The system runs real-time KYC checks using Aadhaar, PAN, and CKYC registry APIs.

• It also checks AML/OFAC/FATCA compliance using external partners (e.g., Refinitiv, Dow Jones).

• I designed the reference architecture that ensures business-IT alignment:

  • APIs securely integrate with regulators.

  • Audit logs are maintained for every transaction.

  • Governance is enforced with EA frameworks and Azure Policy.

3. Credit Assessment & Bureau Check

• Amit’s credit profile is fetched from CIBIL/Experian via bureau APIs.

• A Credit Assessment microservice evaluates repayment history and generates a credit score.

• As EA, I guided the capability model for risk management, ensuring the architecture supports decisioning engines, ML models for fraud detection, and scalability via Azure AKS clusters.

4. Loan Evaluation & Eligibility

• Based on income proofs, property details from Prestige Group, and credit score, an eligibility microservice calculates loan amount, tenure, and EMI.

• I ensured the architecture design covers rules engines for configurable lending policies, and governance checks so business rules remain compliant with RBI/SEBI guidelines.

5. Builder Collaboration & Property Verification

• Prestige Group’s property details (title, approvals, valuation) are validated via integrated APIs.

• The builder portal microservice enables Prestige Group to directly upload required property documentation.

• I defined the enterprise integration blueprint to enable secure, role-based collaboration across external parties while ensuring compliance and data governance.

6. Risk, Compliance & Fraud Checks

• Automated fraud detection services run anomaly checks on Amit’s income vs. loan request.

• Compliance microservices validate against FATCA, AML, and KYC norms.

• I defined the architecture governance model so that all risk checks are logged in a central audit and compliance repository, satisfying internal and regulatory audits.

7. Loan Approval Workflow

• If automated checks pass, Amit’s loan goes for STP (Straight Through Processing) approval.

• If manual review is needed, it routes to a credit officer dashboard.

• As EA, I mapped the process design so both automated and manual paths are supported, ensuring business-IT alignment with flexibility.

8. Loan Agreement & E-Signature

• Once approved, a loan agreement document is generated digitally.

• Amit signs it using e-Sign (Aadhaar/OTP).

• I ensured the enterprise document management service is integrated, with reference architecture for digital signatures and legal compliance.

9. Disbursement to Builder (Prestige Group)

• Loan amount is disbursed directly to Prestige Group’s escrow account in tranches (as per construction progress).

• I defined the integration pattern with the core banking system and escrow management, ensuring transaction governance, security, and audit compliance.

10. Post-Disbursement Services

• Amit can track EMI schedules, make payments, and request statements through a digital self-service portal.

• Prestige Group can view builder-side disbursement status.

• I created the enterprise roadmap for customer experience, ensuring long-term scalability, performance, and integration with AI-driven advisory for cross-sell (insurance, investments).

📌 How This Aligns with EA Role & JD
