Our team was losing too much time on repetitive development tasks - searching documentation, waiting for code reviews, and explaining the same business patterns over and over to new developers. We implemented a complete AI-powered development workflow using two key components: 🔧 Amazon Q Custom Agents We created specialized agents: one for Scala/Spark development, another for CI/CD. Pre-loaded with business rules and code patterns, they provide instant contextual assistance without needing explanations. 🔍 Automated AI Code Review GitHub Action that automatically reviews every pull request using custom prompts tailored to our functional programming standards, providing detailed feedback before human review. Key Insight: Generic AI isn't enough. The magic happens when you customize AI with your domain-specific knowledge, code patterns, and business rules.
