Project Overview

Legal257 is a custom-built case management platform and client portal designed for legal finance advisory services. The system organizes application workflows, document submissions, credit assessments, and advisor-client communication. It replaces manual email-based document exchanges with structured tracking and automated status updates.

The Problem

Advisory workflows are often slowed down by fragmented email communications, manual verification of financial documents, and lack of clarity on application status. Staff members lose hours tracking document submissions, leading to delays in case assessments.

The Solution

We built a secure client application portal and administrative case management dashboard. Clients can upload document files directly, communicate with assigned advisors, and track their application progress. The backend implements role-based access control (RBAC) to keep financial data secure, while automated status updates keep both parties informed.

Architecture & Data Flow

Legal257 connects client portals and advisor dashboards to a central API service. Financial documents are stored securely, and case logs are updated in a PostgreSQL database.

Key Features

Core capabilities implemented to fulfill business requirements and user needs.

Interactive Client Portal

Secure dashboard for clients to submit advisory requests, upload financial files, and track progress.

Case Management Dashboard

Admin panel for advisors to review applications, assign ratings, and log advisory notes.

Role-Based Access Control

Ensures strict document security, preventing unauthorized access to sensitive financial files.

Automated Status Tracking

Pushes automated status alerts to client portals as cases progress through review stages.

Secure Document Sourcing

Encrypted storage paths and access keys to keep patient and advisor communication private.

Activity Audit Trail

Detailed event logging that tracks all document access, status changes, and advisor reviews.

Technical Implementation

Deep dive into code execution, state orchestrations, and API integrations for core modules.

1. Role-Based Access Control (RBAC) Middleware

To secure sensitive financial documents, API endpoints check advisor permissions and assignment statuses before resolving requests.

lib/rbac.tstypescript
import { NextRequest, NextResponse } from "next/server";
import { getUserRoleAndAssignment } from "@/lib/auth";

export async function verifyDocumentAccess(req: NextRequest, documentId: string, userId: string) {
  const user = await getUserRoleAndAssignment(userId);
  
  if (user.role === "admin") return true;
  
  if (user.role === "advisor") {
    // Check if advisor is assigned to the case containing the target document
    const isAssigned = await checkIfAssigned(userId, documentId);
    return isAssigned;
  }
  
  if (user.role === "client") {
    // Check if client owns the target document
    const isOwner = await checkIfOwner(userId, documentId);
    return isOwner;
  }
  
  return false;
}

2. Audit Logging Event Listener

Any changes to case statuses or document access trigger event logs in our PostgreSQL database, establishing a transparent audit trail.

lib/audit.tstypescript
import { db } from "./db";

export async function logAuditEvent(userId: string, eventType: string, details: string) {
  await db.query(
    `INSERT INTO audit_logs (user_id, event_type, details, logged_at) 
     VALUES ($1, $2, $3, NOW())`,
    [userId, eventType, details]
  );
}

Technical Challenges & Solutions

Deep engineering obstacles solved during development, detailing specific logic, tradeoffs, and outcomes.

C1

Challenge

Securing Sensitive Legal and Financial Documents

Resolution

Implemented dynamic access validation and signed tokens.

Financial documents must remain private. We implemented backend validation checks that verify user permissions and case assignments before generating temporary download links.

C2

Challenge

Handling Inconsistent Application Processes

Resolution

Designed a modular status state machine.

Different financial products require distinct approval stages. We designed a state machine database schema that allows administrators to configure custom workflows and validation checks.

C3

Challenge

Managing Audit Trails Dynamically

Resolution

Configured automated database event triggers.

Manual tracking of audit events is prone to human error. We configured event triggers at the database layer to automatically log all data updates and access requests.

Results & Engineering Outcomes

Concrete metrics and operational upgrades delivered through the completed project.

Digitalized Case Management

Replaced fragmented communication with a centralized portal that organizes client applications and review workflows.

Secure Document Exchange

Built a secure upload and access framework that verifies user permissions before resolving document requests.

Transparent Status Tracking

Automated status updates kept both clients and advisors informed, reducing manual check-in requests.
