How to Break Into Tech (With Security in Mind)

Real-time Personally Identifiable Information (PII) Redaction Pipeline with S3 + Lambda + Comprehend
In my previous article, I demonstrated how to use the Amazon Comprehend console to manually detect and redact Personally Identifiable Information (PII) from text files.

The “Stateful” Video: Moving from Random Prompts to Semantic Consistency
In the early days of GenAI, creating a video was like launching a Lambda function with no database—every time you ran it, the AI "forgot" what the character looked like, what they were wearing, or even the laws of physics in the previous scene.As we hit 2026, the industry [...]
Reinforcement Fine-Tuning in Amazon Bedrock: A Practical Guide for Enterprise AI

Amazon Bedrock + Promptfoo: Rethinking LLM Evaluation Methods

I discovered something embarrasing about my LLM development workflow last month. After spending hours crafting what I thought was the perfect prompt for a customer service chatbot on Amazon Bedrock, I deployed it and called it done. My validation process? I asked it five questions, nodded approvingly at the responses, and moved on. Sound familiar? This "vibe-based prompting" approach worked fine until the chatbot confidently told a user that our fictional company offers "24/7 [...]
