# Proposal Management System
|
||
|
|
|
||
|
|
AI-powered proposal generation and management system for Sea Haven Industries. Enables dispatchers to submit proposal requests, uses Bedrock RAG to auto-generate draft line items from historical data, and provides admins with a pricing/approval workspace with professional PDF output.

## Local Development
|
||
|
|
|
||
|
|
### Prerequisites
|
||
|
|
|
||
|
|
- .NET 8 SDK
|
||
|
|
- Node.js 24
|
||
|
|
- Python 3.12
|
||
|
|
- AWS CDK CLI (`npm install -g aws-cdk@2.253.1`)
|
||
|
|
|
||
|
|
### Backend API
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cd api
|
||
|
|
dotnet restore
|
||
|
|
dotnet run --project src/ProposalSystem.Api
|
||
|
|
```
|
||
|
|
|
||
|
|
### Web Frontend
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cd web
|
||
|
|
npm install
|
||
|
|
npm run dev
|
||
|
|
```
|
||
|
|
|
||
|
|
### Infrastructure
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cd infra
|
||
|
|
npm install
|
||
|
|
npx cdk synth
|
||
|
|
npx cdk deploy --all
|
||
|
|
```
|
||
|
|
|
||
|
|
## CI/CD
|
||
|
|
|
||
|
|
- **CI:** Runs on pull requests to `main` (dotnet build/test, tsc, ruff, cdk synth)
|
||
|
|
- **Deploy:** Runs on push to `main` (cdk deploy, frontend S3 sync, CloudFront invalidation)
|
||
|
|
- **OIDC Role:** `githubdeploy-proposal-system`
|
||
|
|
|
||
|
|
## Data Flow
|
||
|
|
|
||
|
|
1. Dispatcher submits proposal request (web or mobile)
|
||
|
|
2. API creates proposal record, publishes SQS message
|
||
|
|
3. If vendor PDF attached: `pdf-extract` Lambda parses and structures data
|
||
|
|
4. Suggestion engine queries Bedrock KB for similar proposals, generates line items via Claude
|
||
|
|
5. Admin reviews/edits line items in workspace
|
||
|
|
6. On approval: `pdf-generate` Lambda creates branded PDF
|
||
|
|
7. On send: `library-ingest` Lambda adds to KB for future matching
|
||
|
|
8. Slack notifications at key status transitions
