My First Exposure to Machine Learning with PyTorch
If you have ever opened a machine learning tutorial and felt like you were reading a math and statistics textbook, you are not alone. I spent months telling myself I would “get into AI eventually”, until I finally arrived at my breakthrough. This is not a textbook breakdown of [...]
Building AI Browser Agents with Browser Use and Playwright
Artificial intelligence is changing how developers interact with the web. Traditional browser automation was originally designed around predefined scripts, rigid workflows, and predictable user actions. Developers manually wrote automation logic that followed exact selectors, buttons, and navigation sequences. While effective, these systems often broke whenever websites changed their layouts [...]
The New Software Stack: AI + GitHub + Cloud
Software development looks very different today than it did five years ago. Developers are no longer working with isolated tools and manual deployment pipelines. Instead, the modern software stack has grown into a connected ecosystem where artificial intelligence, cloud infrastructure, automated DevOps workflows, and collaborative development platforms all work [...]
AI Coding Assistants Are Changing Junior Developer Learning Habits
Human AI workflows are rapidly transforming modern software development. From generating boilerplate code to debugging cloud infrastructure configurations, AI coding assistants are becoming part of the everyday toolkit of developers around the world. For junior developers, this shift is significantly changing how programming is learned. A few years ago, [...]
Connecting the Pieces: How AWS Services Form Cloud Architectures
One of the biggest surprises I encountered while learning AWS was realizing that understanding individual services and understanding cloud architecture are not the same thing. Like many beginners, I started by learning services one at a time. EC2 was a virtual server. S3 was object storage. RDS was a [...]
How to Deploy a Lovable Site to AWS Lambda Using the AWS Lambda Web Adapter
There is a real satisfaction in taking something you built yourself and putting it live on infrastructure you own and control. This guide shows you how to deploy a Lovable site to AWS Lambda using the AWS Lambda Web Adapter, so a page you designed in an afternoon can [...]
The Rise of Human + AI Workflows
I've grown with AI during it's formative years to see how the public's perception constantly shift. AI was once framed as a threat: You vs. AI. Then it became a divide: AI-assisted users vs. non-AI-assisted users. Now, we are entering the real future of work: You + AI. The [...]

Amazon Bedrock’s LLM-as-a-Judge: Automate AI Evaluation with Nova Lite + Claude

Evaluating your LLM’s quality should not cost you too much money or even weeks of your time. You’re probably stuck in a limbo of choosing between two options that have their own drawbacks: Automated metrics like BLEU, ROUGE and accuracy scores? Sure, they are quite fast and cheap, but they ultimately fall short in judging real conversations. Since they simply match word patterns, they're not a good fit for open ended responses simply because [...]

A Beginner’s Guide to the Machine Learning Pipeline on GCP

When people hear the term "machine learning," they often imagine complex math, advanced algorithms, or mysterious "AI magic" happening behind the scenes. In reality, machine learning on the cloud is far more practical and structured than it may sound. At its core, an ML pipeline is a series of steps that transform raw data into useful predictions. Think of it like a typical software workflow: You prepare your code You build the application You [...]

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.
