P2P Crowdfunding Solution for Short-Term SME Financing

The Requirement

A Secure and Compliant Platform

They needed a solution that could:

Manage non-banking payment flows and digital wallet transactions
Support a real-time auction and bidding system with bid ranking, sequencing, and split-bid support
Provide full transaction traceability, including credits, debits, collections, intermediary payments, and charitable distributions
Automate post-auction workflows, including bid approvals, repayment schedules, and installment tracking
Maintain regulatory compliance, multi-currency support, and data transparency for all stakeholders

Our Solution

A Laravel-based Crowdfunding Platform

We proposed developing a secure, compliant crowdfunding platform using a Laravel back-end, a Dockerized microservices architecture, RabbitMQ for real-time bidding events, and a React + Flutter front-end stack for seamless web and mobile experiences.

Workflow

01

Discovery & Requirements Mapping

We worked closely with the client to map complex payment flows, bidding logic, compliance rules, and fund lifecycles, and to define APIs and microservice boundaries.

02

System Architecture & Technical Design

We designed a Docker-based microservices architecture with isolated services for:

Bidding Engine
Wallet & Payment Service
Compliance & Audit Service
User & Access Management
Notification Service

We implemented RESTful APIs with OAuth2 and JWT authentication. For asynchronous event handling and reliable, cross-service communication, we used RabbitMQ.

03

Module Development (Web, Mobile, and Admin Consoles)

Back-end: Built using Laravel, MySQL (transactions), Redis (real-time caching), and Laravel Passport (OAuth2).
Web App: Developed using React.js, React Hooks, Webpack, and Babel for optimized builds.
Mobile Apps: Developed using Flutter with a shared codebase for iOS and Android, integrated with APIs and Firebase push notifications.
Admin Panel: Provided comprehensive transaction visibility with role-based access, Elasticsearch logs, and real-time monitoring dashboards.

04

Integration & Automation

Implemented digital wallet services, fund distribution logic, repayment schedulers, and EMI generation through cron jobs and Celery tasks.
Integrated bidding engine with RabbitMQ-driven live events for ranking, sequencing, and split-bid allocation.
Added Elasticsearch + Logstash for audit trails, compliance visibility, and event monitoring.
Automated onboarding flows, KYC validations, and notification pipelines.

05

Testing, Compliance Validation & Deployment

Conducted thorough QA and testing to validate transaction handling and concurrency under auction pressure.
Ensured compliance readiness with activity logs, immutable transaction records, and audit trails.
Deployed via containerized CI/CD pipelines, enabling seamless versioning and scalable rollouts across services.

06

Testing and Deployment

Before delivering the final solution, we conducted extensive QA and testing, along with multiple UAT cycles, to ensure it aligned with the firm's operational workflows and met compliance requirements.
