BriefSmart AI — Client Onboarding Automation

Sole developer, end to end · Feb 2026 – Mar 2026

An AI platform that ingests sales call transcripts, documents and notes to auto-generate structured, versioned onboarding briefs — replacing manual sales-to-delivery handoff review.

Orchestration

A Node.js/TypeScript REST API drives a Python multi-agent LLM pipeline through child-process orchestration, with Server-Sent Events streaming real-time pipeline progress to the client. The SSE client is hand-rolled on fetch and ReadableStream for cross-proxy and HTTP/2 compatibility.

Dual-database design

PostgreSQL via Sequelize for relational data, MongoDB for AI-generated schema-flexible content, with the Node layer mapping between them.

Avoiding wasted LLM calls

SHA256-based file-change detection drives delta regeneration of a multi-section generated document, so unchanged source material never triggers a model call. Prompt-level source-priority rules let explicit internal notes override call-transcript content.
