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)
Let’s talk honestly for a second. If you want to break into tech securely, you need to think differently from the start. A lot of people say they want to “break into tech,” but very few think about structure, architecture, and security from day one. What they usually mean [...]
Stop Running OpenClaw on Your Laptop: How I Built a Secure Personal AI Assistant Using Amazon Bedrock
I'll admit. The first time I heard about OpenClaw and its features, I was obsessed. The idea of having an AI that could actually do stuff rather than just giving responses to prompts felt like living in the future. As a university student, it’s a given that I have [...]
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 [...]

Building a Cost-Aware RAG Application with Amazon Bedrock

What if your Client can have a Chatbot that throws a highly accurate responses based on your documents? Without having a guilt of the monthly expenses. Without even subscribing to any costly, AI-support subscriptions. Only pay per inquiry requests to your model provider, and of course only costs you cents, and it lessens when your client is already satisfied with the answer, as it returns a fully verified response based from the documents you [...]

Zero-Sweat: A Comprehensive Guide to IAM Policy Autopilot

Picture this: your application works perfectly on your local machine. You deploy it to AWS, then immediately hit an “Access Denied” error. If you’ve worked with AWS for any length of time, you’ve experienced this. What follows is usually a frustrating dive into IAM documentation, trial-and-error permission updates, and lost development momentum. AWS Labs created IAM Policy Autopilot to solve exactly this problem. IAM Policy Autopilot analyzes your application code and generates AWS IAM [...]

The Year of the Agent: Anthropic’s Claude AI Models and Agents

Looking back on the past year of 2025 coding with the help of artificial intelligence, we can safely say that it was the year of agents, especially pioneered by Anthropic with Claude Code. AI products have matured to offer highly reliable agents that can understand, navigate, and work seamlessly on large codebases. It is the end of the old ways: of manually copying and pasting code into web AI applications. Agents are now [...]

AI-Driven Cloud Security at AWS re:Invent 2025

Cloud computing continues to accelerate at a pace that traditional security models were never designed to support. Development teams now provision infrastructure in minutes, deploy services continuously, and scale applications automatically. However, security processes often lag behind this speed. In many organizations, security still enters the workflow after key architectural decisions are already finalized. As a result, teams spend more time fixing problems than preventing them. Although many organizations attempt to shift security earlier [...]

Amazon Q in Practice: How AWS’s AI Assistant Actually Works for Businesses and Developers

Amazon Q is often introduced as AWS's generative AI assistant, but that description doesn't really explain why it exists or how it behaves once you start using it. If you treat Amazon Q like a general chatbot, it can feel restrictive or underwhelming. If you treat it as an AWS-native system designed around identity, permissions, and retrieval, it becomes much easier to understand. And much more useful. I've spent a lot of time working [...]

AWS Security Agent: Context-Aware Application Security

The Problem: Security Can't Keep Up In the current engineering landscape of our industry, modern software teams are supposed to be built to be able to move fast. Continuous integration, automated deployments, and agile workflows have seen the rise of weekly and even daily releases to be the norm. With rising business and customer demands in the time of rapid advancements in technology, new features, fixes, and changes are constantly pushed to production. However, [...]

Automating PII Detection and Redaction with Amazon Comprehend

Organizations today are entrusted with enormous amounts of sensitive information. Customer support logs, healthcare records, financial transactions, and even training datasets often contain Personally Identifiable Information (PII) such as names, phone numbers, email addresses, or credit card numbers. Protecting this information is not just a matter of compliance with regulations like GDPR, HIPAA, or PCI DSS. It is also central to maintaining customer trust and reducing the risk of data breaches. Amazon Comprehend, a [...]

Build a Model-Agnostic AI Text Summarizer Web Extension

Browser extensions are a great way to bring AI directly into your everyday workflows. Instead of copying text into external tools and websites to be summarized, you can do it right on the page. In this tutorial, we'll build a lightweight, model-agnostic Chrome extension that summarizes selected text using AI. With a simple right-click, users can send any highlighted text to an AI model of their choice and instantly view a concise summary in [...]

AWS Lambda Managed Instances: Serverless Simplicity with EC2 Control

AWS Lambda Managed Instances marks a significant evolution in serverless computing. For years, standard Lambda was the default for running code without infrastructure management, but it offered limited control over the underlying hardware. This new capability changes that by combining serverless simplicity with Amazon EC2 flexibility. Announced at AWS re:Invent 2025, this feature enables Lambda functions to run on designated Amazon EC2 instances. You choose the hardware configuration, while AWS manages the infrastructure. [...]

How to Generate Simple Document Embeddings with Python

Document embeddings are one of the simplest ways to give machines an understanding of text, and in our previous article, Document Embeddings Explained: A Guide for Beginners, we explored how they turn entire documents into dense numerical vectors that capture meaning and context. Now that you understand what embeddings are and why they’re useful for tasks like semantic search, classification, and clustering, this tutorial will show you how to generate them in practice using [...]
