Build production services using Python, FastAPI and Pydantic models.
Develop APIs and backend workflows that support AI-enabled document and contract intelligence.
Work with PostgreSQL, SQLAlchemy and Alembic to model, migrate and operate reliable data layers.

Use AI coding tools to accelerate implementation, debugging, refactoring, testing and documentation, while maintaining high code quality.
Improve developer experience by reducing boilerplate, improving test coverage, simplifying local setup and documenting repeatable patterns.
