A private, secure, serverless voice assistant backend designed for integration with Home Assistant and other smart home platforms. Built with AWS (API Gateway, Lambda, Polly, Transcribe, S3) and a security-first mindset.

• Voice→Intent→Action: Convert voice commands to secure smart home actions.
• Privacy by Design: All secrets stored in AWS Secrets Manager. No third-party data leaks.
• API Security: API Gateway with API Key (optionally Cognito), strict IAM, encrypted storage.
• Home Assistant Integration: REST commands, automations, and secure token use.

    [Secrets in AWS Secrets Manager]

• AWS account (IAM user with least-privilege, MFA enabled)
• Node.js/Python (for Lambda)
• Home Assistant (HA) instance with HTTPS and Long-Lived Access Token

git clone https://github.com/yourusername/jarvis-personal-assistant.git
cd jarvis-personal-assistant/infra
pip install -r requirements.txt  # or npm install

• Define AWS resources using Pulumi/Terraform (see infra/).
• Store all secrets (HA token, API keys) in Secrets Manager.

• Add rest_command to HA configuration.yaml to call API Gateway endpoints with API Key.
• Use HA automations/scripts to trigger voice/intent actions.

• Secrets: Never hardcode. Always use AWS Secrets Manager or SSM Parameter Store.
• IAM: Use narrowly scoped roles for Lambda/API Gateway.
• API Gateway: API Key required for all endpoints; consider Cognito for multi-user.
• S3: All audio files encrypted at rest, presigned URLs expire quickly.
• Logging: All access/events logged in CloudWatch (audit-ready).

• Voice command to intent (NLU)
• Home Assistant state query/response
• User authentication with Cognito
• Automated security scanning (CI/CD)
• Multi-environment deploys (dev, staging, prod)

• Fork, branch, and PR (feat/refactor/fix/chore).
• All code must pass security and lint checks before merge.
• See CONTRIBUTING.md for details.
