Architecture Decision Records (ADRs) document the reasoning behind important engineering choices. They explain what was selected, why it was selected, which alternatives were considered, and what trade-offs were accepted.
The records below focus on the technical decisions behind the AI Business Assistant & CRM, a practical application integrating conversational AI, customer management, secure REST APIs, and SMS communication.
Code shows what was built. Architecture explains how the system is organized. Architecture Decision Records preserve the engineering reasoning behind important choices.
Documenting decisions improves maintainability, supports future development, and helps other engineers understand the context in which a technology or design was selected.
These ADRs provide a record of the architecture decisions supporting the AI Business Assistant & CRM.
Selection of FastAPI as the backend framework for REST APIs, AI integration, request validation, API documentation, and Python-based application development.
Read ADR-001Selection of PostgreSQL as the primary relational database for CRM records, appointments, SMS history, chat messages, and other persistent application data.
Read ADR-002Selection of OpenAI APIs for conversational AI, customer inquiry handling, information extraction, and AI-assisted business workflows.
Read ADR-003Planned documentation of cloud hosting decisions, deployment strategy, CI/CD integration, infrastructure considerations, and future scalability.
Coming SoonPlanned documentation of architectural boundaries between the presentation layer, API endpoints, business workflows, external services, data storage, and infrastructure.
Coming SoonAdditional decisions may document authentication, authorization, messaging integration, deployment, testing strategy, and future AI capabilities as engineering requirements evolve.
Back to Knowledge CenterA system becomes architecture when every design decision can be explained.
Great software is built with code. Great architecture is remembered through decisions.
