LexPanel

A legal practice management application built to replace the Excel-based workflows of small law firms.

Status: Active development — core case and financial modules complete, multi-tenant SaaS architecture in progress.

The Problem

Small law firms run on spreadsheets. Case lists, hearing dates, client advances, attorney fees, office expenses — all tracked manually across multiple Excel files. Data gets lost, calculations drift, and there's no single source of truth.

LexPanel replaces that workflow with a structured, purpose-built application.

Architecture

LexPanel.Domain          → Entities, Enums, Interfaces (zero external dependencies)
LexPanel.Application     → CQRS Commands/Queries, DTOs, Validators, Behaviors
LexPanel.Infrastructure  → Persistence, Repositories, Services, Security
LexPanel.API             → Controllers, Middleware, Program.cs
frontend/                → React application

Key patterns:

• Unified ApiResponse<T> envelope across all endpoints
• MediatR pipeline: validation → authorization → handler
• Generic repository with multi-field sort and search
• Audit fields (CreatedAt / UpdatedAt) populated automatically via SaveChangesAsync

---

Roadmap

• Case management (list, detail, CRUD)
• CMK assignments
• Mediation cases
• Contact directory
• Financial ledger with transaction rules
• Dashboard summary
• Excel import / export
• Multi-tenant architecture (multiple firms)
• Role-based access control (Owner / Lawyer / Assistant / Viewer)
• Hearing calendar view
• Global search (Ctrl+K)
• Mobile / responsive layout
• Cloud deployment
