Full-Stack Developer for Legal Tech AI Platform

Duration: 2 weeks.
Location: Remote
Start Date: Within the next 2 weeks.

About the Project
We have a legal SaaS platform (multi-tenant, case-based system) that is partially complete but needs expert hands to finalize stability, tighten security, and build out critical new features. This project was vibe-coded by a not-so-smart lawyer, so the existing codebase needs refinement, cleanup, and professional-level hardening before we can move to launch.

Scope of Work

Review & Optimization Tasks:

1. Code Stabilization & Cleanup – Remove unnecessary bloat, ensure stable performance across the app.
2. Security Hardening – Implement OTP-based user authentication; ensure best practices for secure React/TypeScript applications.
3. Tenant Data Isolation – Verify and enforce that all tenants are fully siloed; no cross-tenant data access possible.
4. Internal Notification System Fixes – Repair internal app notifications, SMS notifications, and email alerts to notify users when clients send messages.
5. LLM Integration Update – Replace OpenRouter LLM integration with Azure OpenAI API integration.

New Feature Development:

1. Sidebar for In-App Word Processor – Extend the existing in-app Word document processor by adding a sidebar for AI drafting and editing.
2. RAG PDF Processing System – Integrate an open-source Retrieval-Augmented Generation (RAG) library to parse large PDF record sets and output structured JSON for the platform to convert into medical chronologies and demand letters (no from-scratch NLP work required).
3. Telynx Voice Agent API Integration – Switch from Vapi API to Telynx and set up for outgoing calls.
4. Lob API Mail Integration – Connect the mailbox feature to the Lob API so users can physically mail documents with one click.

Required Skills & Experience:

• Advanced React and TypeScript/Javascript expertise.
• Strong understanding of application security & compliance for SaaS (multi-tenant systems, SOC2 compliance, secure authentication).
• Experience with multi-tenant architecture and strict data siloing.
• Proficiency with Azure OpenAI API integrations.
• Strong backend integration skills for APIs (SMS, email, telephony, AI, mailing).
• Familiarity with RAG pipelines and working with large document sets.
• Ability to work in and improve partially completed “vibe-coded” codebases.

Nice-to-Have Skills:

• Experience with legal tech or healthcare data systems.
• Familiarity with document editing libraries in React.

Deliverables:

• Fully stabilized, secure, and optimized codebase.
• OTP authentication implemented.
• Verified tenant isolation.
• Fully functional notification system.
• Azure OpenAI integration live and tested.
• Sidebar AI generate word processor feature.
• RAG PDF-to-JSON processing system integrated and functional - generate medical chronologies and demand letters based on references.
• Vapi API configured for outbound AI Agent calls.
• Lob API integration for one-click physical mailing operational.

How to Apply:
