The Economics of AI Infrastructure: Understanding AWS AI Factories
Artificial intelligence has shifted from being a software innovation challenge to becoming an infrastructure challenge. Organizations no longer struggle primarily with model design. Instead, organizations are increasingly challenged by compute density, energy consumption, networking scale, and operational complexity when deploying modern AI systems. As large-scale generative AI systems become [...]
Deploying an AWS Application Load Balancer (ALB) Using Terraform
If you’ve tried building an ALB manually in the AWS Console, you already know the drill create a VPC, configure subnets, set up security groups, launch EC2 instances, create a target group, add listeners, and then double check everything because one small misconfiguration can break the whole setup. It [...]
How to Break Into Tech (With Security in Mind)

Improving Application Security with AWS Security Agent
Modern software teams are very fast today. Code is pushed daily. Pipelines deploy automatically. Features reach users quickly. This is the success of DevOps. But security often does not move at the same speed. In many organizations, security reviews are still scheduled monthly or quarterly. Penetration tests require coordination. [...]
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 [...]

How AWS IAM Handles Conflicting IAM Policies

Overview When a user attempts an action in AWS, such as launching an EC2 instance or listing S3 buckets, AWS evaluates all involved IAM policies to determine whether to grant the request. Since IAM policies can be associated with various types of identities, the hierarchy of these identities influences the final permissions for a user. AWS IAM Policy Evaluation Flow Let’s break down the process of how AWS evaluates a request using the simplified [...]

Understanding the IAM:PassRole Permission

Introduction Many AWS services often require the use of an IAM role to execute actions on your behalf. For example, when you create a Lambda function, you assign an execution role to it. AWS can generate one for you automatically, and then you define the permissions you want it to have after. Most of the time, that's the case. However, there are instances when you might choose to associate an existing IAM role. In [...]

Different Ways of Passing Parameters Securely in CloudFormation

Introduction When writing CloudFormation templates, it's a security best practice to avoid hardcoding sensitive info, like client secrets, API keys, or passwords. Sharing templates with hardcoded details by mistake can put your infrastructure and data at risk. In this article, we'll explore different secure methods to pass parameters in CloudFormation templates. Using the NoEcho Attribute To avoid hardcoding parameters in your template, you can define them during stack creation using the Parameters section. However, [...]

Automate Confluence Backup Using AWS Step Functions

Introduction In this article, I'm gonna show you how you can create an automated Confluence backup in Atlassian using an AWS serverless solution. The motivation behind this article stems from a recent task I was working on a couple of weeks ago. My goal was to run a scheduled backup of Confluence data and export it to Amazon S3. Since Confluence backups are deleted 14 days after creation, it’s a good idea to have [...]
