[GSoC 2026] FINERACT-2442 - Loan Origination System Architecture Overview

[sujan kumar <su...@gmail.com>]

Hi All,

I am Sujan, a GSoC 2026 contributor working on FINERACT-2442: Loan
Origination System (LOS) for Apache Fineract.

The goal of this project is to build a modular Loan Origination System that
manages the lifecycle of a loan application before it reaches the core
lending workflow in Fineract. The system is designed to support application
intake, document verification, credit assessment, approval workflows, and
eventual loan disbursement integration.

Proposed architecture overview:

   - Domain-driven design with dedicated entities representing loan
   applications, applicants, documents, approvals, and scoring outcomes.
   - State machine-based workflow to model and enforce loan application
   lifecycle transitions.
   - Layered architecture consisting of REST APIs, service layer, domain
   layer, and repository layer.
   - Configurable approval workflow to support different approval paths and
   decision outcomes.
   - Credit scoring module designed to evaluate applicants and assign risk
   categories based on configurable scoring criteria.
   - Disbursement bridge planned as the integration point between the
   origination workflow and Apache Fineract's lending domain.
   - Comprehensive API documentation and CI/CD quality checks aligned with
   Apache standards.

The objective is to keep the solution modular, extensible, and suitable for
future enhancements such as alternative credit scoring models, external
integrations, and multi-stage approval processes.

I would appreciate any feedback from the community regarding the
architecture, domain modeling approach, workflow design, or other
considerations that should be taken into account as development progresses.
Early feedback is especially valuable while the design is still evolving.

Looking forward to your suggestions and discussions.

Best regards,

Sujan Kumar

Hi All,

Following up on my earlier note  it's been about a month since we started
coding, so wanted to share progress.

Repository:

https://github.com/apache/fineract-loan-origination

Completed so far:
- Standalone Spring Boot 4.1 service with CI pipeline.
- Domain layer: 4 enums and 5 JPA entities covering the full loan
application lifecycle, with optimistic locking, multi-tenancy, and audit
trails.
- Repository layer: tenant-scoped query interfaces
- State machine enforcing all valid lifecycle transitions
 (DRAFT→SUBMITTED→UNDER_REVIEW→APPROVED/REJECTED/REFERRED  → DISBURSED),
with unit tests
- Credit scoring engine in progress — pluggable scoring factors with
weights configurable via application.yml, following CGAP microfinance
guidelines.

Architecture decisions are documented as ADRs in docs/adr/ for anyone who
wants to understand the reasoning  particularly why this is a standalone
external service rather than embedded in Fineract core, and why a custom
state machine was chosen over a BPMN engine.

Next up: finishing the scoring engine, then approval workflow and the REST
API layer.

Still very open to feedback on the approach.

JIRA: https://issues.apache.org/jira/browse/FINERACT-2442

Best regards,
Sujan
