Achieve AWS Mastery with LocalStack

2025-10-01T13:57:23+00:00

Imagine if there is a way to learn AWS without ever needing an internet connection, learn to test your infrastructure locally, run AWS services on your machine? Well, there's this thing called LocalStack in which allows you to run AWS in your machine. You can test out different services, learn how to connect each of it, test out how they can work together, and maybe testing out an application that uses a specific service that you cannot test locally. In this blog, I will guide you through on how to set it up and the things that you can do [...]

Zero-Infrastructure Vector Search with Amazon S3 Vectors

2025-08-22T14:27:33+00:00

  The world of generative AI is evolving at a rapid pace and one of the most powerful and practical applications is Retrieval-Augmented Generation (RAG). RAG enhances Large Language Models (LLMs) by giving them access to external, up-to-date knowledge bases. This allows them to generate more accurate and context-aware responses. Traditionally, building a RAG system required setting up and managing a separate vector database that adds complexity, cost, and a new layer of infrastructure to maintain however with the introduction of Amazon S3 Vector Buckets a new paradigm has emerged: zero-infrastructure vector search. What is Zero-Infrastructure Vector Search? Amazon S3 [...]

Renovate Your Second Home: Terminal with Amazon Q

2025-06-14T12:01:09+00:00

For many developers, the terminal is not just a tool to make you look cool but it is a sanctuary. It deserves the title "A Developer's Second Home." Here, we build what we want, everything flows freely, and productivity reigns. However, comfort doesn't mean we can't tinker and upgrade it. In this blog, we'll explore how Amazon Q can renovate our sanctuary to make life easier. We need to improve our terminal experience from simple scripting with vim or nano to navigating directories and configuring systems. Your Terminal, Reimagined: The AI Renovation Has Begun The command-line interface (CLI) has been a [...]

Giving LLM Superpowers: The Magic of Model Context Protocol

2025-05-22T16:03:46+00:00

Large Language Models (LLMs) are already incredibly  powerful. They can generate human-like text, answer complex questions, and even write code. LLMs are great at creating content we can easily read and use but what if we could elevate them beyond just content creation? What if we could give them tools they could understand, use, and execute on their own? They would just need a simple description of the tools they have access to. Imagine giving your LLM superpowers, allowing it to do more by simply providing it with context about the tools you use and have. This isn't a futuristic [...]

Signed, Sealed, Secured: Amazon S3 Style

2025-04-11T10:08:31+00:00

Building applications requires extensive planning, ranging from UI design and data flow to database interactions. However, one of the most crucial aspects is figuring out how to allow users to save files such as images, PDFs, and videos  securely and reliably within our application. Fortunately, AWS offers a robust and scalable service for handling file storage: Amazon Simple Storage Service (S3). Nevertheless, the real challenge lies in controlling how users upload and download their files. While Amazon S3 is simple to use, it’s essential to ensure that the interactions between our application and S3 are reliable, fast, and secure. Therefore, [...]

Build a Web-Based Linux Terminal Playground

2024-12-09T04:51:18+00:00

In this blog, I will guide you through creating a Simple Web-Based Linux Terminal Playground that enables running Linux commands directly in the browser. We will use technologies such as Podman for containerization, React for the UI, and Express and node-pty for the backend. WebSockets will handle real-time communication between the frontend and backend, creating a seamless, secure, and interactive environment to learn and execute Linux commands. Each connection will be isolated and ephemeral therefore ensuring security and separation between users. Why Use Podman, React, Express, node-pty, WebSockets, and Alpine? Why Podman? Podman is an open-source container engine that focuses [...]
