Lending & HR SaaS on AWS

01

The problem & context

Fund Flick, by Maitrii Infotech, is a lending operations suite for LAP, MSME, vehicle, business, personal, and gold lenders. One SaaS platform covers lending work and the HR suite, with AI agents for HR, on the web and in the Fund Flick app for field officers, collection agents, and managers.

Architecture

Illustrative view of the Fund Flick platform. A Next.js web dashboard and the React Native Fund Flick app call Node.js and FastAPI services on AWS Lambda. Lending modules handle loan origination, collections, and tasks, with push notifications to field staff, while the HR suite manages people, payroll with outward payments, attendance, and leave. Records live in MongoDB, HR letters, uploads, and exports in Amazon S3, and LangGraph agents add HR assistance traced in LangSmith. CloudWatch and Datadog monitor the platform.

Architecture: HR AI agents

Illustrative view of the Fund Flick HRMS. A Next.js dashboard and the Fund Flick Android app call a FastAPI backend running on AWS Lambda, which stores employees, payroll, attendance, and leave in MongoDB Atlas. LangGraph agents built with LangChain answer HR policy questions by retrieving policy chunks through MongoDB Atlas Vector Search, draft HR letters stored in Amazon S3, summarize payroll and attendance reports, and parse uploaded resumes and onboarding documents. LangSmith traces the agents, and CloudWatch and Datadog monitor the platform.
