Demo apps, playbook QA tools, and workflow demo UIs for validating and showcasing legal AI capabilities.
2024.12 — 2026.03 BHSN AI Engineer
Demo PoC Playbook
Overview
Built demo applications and QA tools for internal validation and external showcasing of legal AI capabilities. Developed apps for various purposes including AI Review performance verification, playbook management automation, and workflow demonstrations.
Key Achievements
- Built AI Review performance QA page: provided a structured interface for systematically verifying review results
- Automated playbook uploads: implemented an end-to-end pipeline from file upload to Google Drive storage to SQL synchronization
- Implemented per-workspace playbook overlay system: applied customer-specific custom rules on top of shared playbooks
- Built legal workflow demo with RAG search and streaming API
Lawyer-in-the-Loop Platform
Beyond a simple demo app, built a self-serve playbook platform where lawyers directly create checklists, test them on sample contracts, and selectively deploy to specific clients:
- Excel-based playbook authoring → upload testing → final version Drive upload → QA zone deployment
- Separated LATEST from existing releases to manage iterative revisions vs. currently deployed versions
- Overlay structure where specific workspaces customize certain playbooks while keeping the shared base intact

Technical Approach
- Designed a self-serve workflow where lawyers create checklists, test in a demo environment, go through QA approval, and deploy to customers
- Implemented a demo UI displaying real-time results using RAG-based search and SSE streaming API
- Automated playbook management and deployment to enable non-engineers to operate the system directly
- Built workflow gallery with builder/runner UX supporting JSON import/export for a fully interactive demo app
