AWS Bedrock Guardrails Architecture

The Missing Layer in Your Enterprise AI Stack: AWS Bedrock Guardrails

Everyone wants to ship AI into production. Almost no one wants to own what happens when it goes wrong. I’ve been in enough rooms with financial services clients to know how this plays out. A team builds something impressive on Bedrock — a RAG-powered knowledge assistant, an internal compliance copilot, a customer-facing chatbot. The demo looks great. Then someone in Legal raises their hand. What happens if it leaks a customer’s SSN? What if it makes a recommendation that sounds like investment advice? What if a clever user tricks it into ignoring your system prompt? ...

Student Branding Starter - Sample Portfolio Website

Building Your Personal Brand: A Student's Guide to Online Presence

What does your online presence say about you? For many students, searching their name online brings up little more than a LinkedIn profile and perhaps some social media accounts. This limited visibility can make it challenging to stand out professionally or showcase your actual skills and projects. A personal website offers a solution - providing a dedicated space where you can control your professional narrative and present your work on your own terms. ...

Designing Pre-Trade Risk Controls on AWS (SEC Rule 15c3-5)

Introduction On August 1, 2012, Knight Capital Group—one of the largest market makers on the New York Stock Exchange—lost $440 million in 45 minutes due to a software deployment failure. The incident nearly bankrupted the firm and sent shockwaves through financial markets. While the technical details are fascinating, the real lesson lies in what wasn’t there: an effective, centralized mechanism to stop runaway automation before catastrophic losses occurred. This post explores how modern streaming architectures using Apache Kafka and Apache Spark can implement the kind of real-time risk controls that regulations now require—and that Knight Capital desperately needed. We’ll connect the dots between a historic trading disaster, regulatory requirements, and a hands-on demo you can deploy yourself. ...

Building a Cost Optimization Agent with AWS Bedrock and Cost Explorer

Managing AWS costs becomes increasingly complex as infrastructure grows. Organizations often struggle with cloud cost management, spending valuable engineering time manually analyzing Cost Explorer data, identifying optimization opportunities, and implementing changes. Even with dedicated cost management tools, the analysis and remediation process remains largely manual, requiring specialized expertise to interpret cost data and translate it into actionable steps. This post demonstrates how to build an automated agent that analyzes AWS costs and generates actionable recommendations to reduce cloud spend. By combining AWS Bedrock’s analytical capabilities with Cost Explorer data, the system identifies cost outliers and provides specific optimization steps that go beyond basic visualizations to deliver meaningful insights. ...

Building a GitHub PR Reviewer with Bedrock Agents and Action Groups

Code reviews are essential for maintaining code quality, but they can be time-consuming and often repetitive. Developers find themselves commenting on the same issues across multiple pull requests: missing tests, inconsistent naming, inadequate error handling, and numerous other routine concerns. This creates a bottleneck in the development process, as team members wait for their code to be reviewed while reviewers struggle to balance thorough reviews with their own development work. ...

Building a Company Knowledge Bot: Slack + Bedrock Knowledge Bases

“Where can I find our vacation policy?” “What’s the process for requesting new hardware?” “Can you explain our security guidelines?” These questions echo through company Slack channels daily, interrupting workflows and creating redundant work for team leads and HR staff. The same questions get asked repeatedly, and answers are buried in documentation that’s difficult to navigate. In this post, I’ll show you how to build a simple yet powerful Q&A bot for Slack that leverages your company’s documentation to provide accurate, contextual answers. The best part? It runs entirely on AWS managed services, minimizing operational overhead while delivering immediate value to your organization. ...

The Week of the Moltbots - OpenClaw and autonomous agents

The Week of the Moltbots

I wrote this article for Ippon on February 10, 2026. The enthusiasm around projects like OpenClaw—an open-source framework enabling autonomous task execution across messaging platforms, file systems, and enterprise APIs—reveals a critical blind spot in enterprise technology governance. For an entire week, I heard nothing but discussions of moltbots, OpenClaw, Clawd, and various implementations being created with these tools. But when I realized the permissions being exposed and how enterprises were approaching agent governance, I felt compelled to document this moment in AI history. ...

Richmond AWS User Group - FastMCP Demo

Richmond AWS User Group: FastMCP Demo on AWS

Live Demonstration of FastMCP on AWS The February meetup of the Richmond AWS User Group featured a hands-on demonstration of FastMCP on AWS, exploring how modern agent frameworks can be deployed and operated in real cloud environments. Rather than focusing on theoretical concepts, the session provided attendees with practical insights into what it actually takes to run AI agent frameworks in production. Behind the Scenes: Unscripted AI Engineering What made this demonstration particularly authentic was that I hadn’t tested the solution beforehand. Armed with an impressively detailed prompt I’d crafted (available on GitHub), I wanted to make this a genuinely live experience—including all the potential hiccups and surprises that come with real AI development. ...

Reference Architecture for Safe Generative AI on AWS for Regulated Environments

From Prompt to Production: Designing Safe Generative AI on AWS for Regulated Environments

The Real Problem: Production, Not Prototypes Everyone can demo generative AI. Almost no one can run it safely in production. Enterprises in finance, healthcare, and the public sector aren’t blocked by technology capabilities—they’re blocked by governance requirements that today’s AI implementations rarely satisfy. These organizations face three critical blockers: Data leakage risk: Sensitive information, from PII to trade secrets, flowing through public model APIs Lack of auditability: No reliable record of prompts, responses, or who accessed what information Unclear ownership: Ambiguous rights over prompt engineering IP, training data, and generated outputs AWS customers don’t want AI that behaves like a chatbot toy. They need AI that behaves like enterprise infrastructure: secured, monitored, audited, governed, and compliant with their existing security posture. ...
