• Built and maintained IMS Campaign Manager, cloud-native FastAPI backend for P&G media campaign planning platform, supporting marketing teams with digital ad campaign planning, approval, tracking, and reconciliation across global publishers.
• Used Python 3.13, FastAPI, and layered router -> service -> repository design with FastAPI Depends dependency injection to keep service and repository logic stateless.
• Implemented data access with SQLAlchemy 2.0 ORM on Google Cloud Spanner through sqlalchemy-google-spanner for transactional storage and Google BigQuery through sqlalchemy-bigquery for reporting and analytics queries.
• Reduced FastAPI cold-start latency by configuring Redis distributed caching, startup cache warming, and fastapi-cache2 in-memory caching, along with lazy dependency and router loading.
• Developed 20+ versioned REST routers using Pydantic v2 models for enhanced request and response validation and comprehensive OpenAPI documentation.
• Integrated LangGraph and langgraph-supervisor multi-agent flow with langchain-openai supervisor agent that routed natural-language planning requests to specialized ReAct sub-agents for planning data, campaign mapping, knowledge retrieval, and RAG search.
• Applied JWT authentication with PyJWT, environment-based secret management through Pydantic Settings, CORS policy enforcement, and gitleaks pre-commit secret scanning.
• Used Poetry, Docker, Black, isort, mypy, pylint, pre-commit, Commitizen, pytest, pytest-cov, fakeredis, and pytest-mock for development, testing, and code quality, with SonarQube and Google Cloud Run, Secret Manager, Cloud Tasks, and Cloud Logging for delivery and deployment.

Project Details.
