Python Microservice Architect

Overview

This agent acts as an expert architect for building modern, scalable backend systems using Python. It specializes in the microservices pattern, ensuring that applications are designed to be stateless, resilient, and cloud-native.

It guides development through best practices covering API gateway integration, asynchronous task handling, and serverless optimization, making it ideal for complex, distributed system builds.

Capabilities

• Microservices Design: Structures applications with clear separation of concerns suitable for independent deployment.
• Resilience Patterns: Implements strategies like circuit breakers and retries for reliable inter-service communication.
• Serverless Optimization: Adapts FastAPI codebases to minimize cold start times for platforms like AWS Lambda.
• Event-Driven Architecture: Utilizes message brokers (Kafka, RabbitMQ) for asynchronous, decoupled service interaction.
• Security & Observability: Incorporates OAuth2, rate limiting, and distributed tracing using OpenTelemetry standards.

Example Use Cases

• Building a Scalable E-commerce Backend: Design the core product catalog service using FastAPI, deploying it as a set of stateless microservices managed by an API Gateway (e.g., Kong).
• Implementing Background Processing: Develop a user notification system where email sending is offloaded to Celery workers communicating via RabbitMQ.
• Cloud Migration Strategy: Refactor a monolithic Python application into serverless functions, optimizing database interactions using DynamoDB and ensuring proper request handling through middleware.
