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. While this hands-on method is excellent for learning the fundamentals of PII detection, it’s not practical in real-world, high-volume environments where speed and accuracy [...]
Are AI Engineers the New Full-Stack Developers?
Something has been quietly shifting in the tech industry. Job titles that used to sit in completely separate corners of a hiring platform are starting to blur together, and engineers on both sides are feeling it. The full-stack developer who's suddenly expected to integrate LLMs. The AI engineer who's [...]
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
Large language models are powerful, but power alone is not enough for enterprise AI. A model may generate fluent responses, yet still miss your company’s tone, fail structured validation rules, or produce outputs that are technically correct but operationally unusable. The real challenge is not just making models smarter, [...]
Don’t Install OpenClaw! (Unless You Read This First)
If you have been on Twitter, TikTok, or GitHub recently, you have probably seen the hype. Clawdbot (now rebranded as OpenClaw) promises something bold: a self-hosted AI employee that runs on your Mac Mini, has terminal access, and takes instructions through messaging platforms like Telegram. It sounds powerful. It [...]
