𝗵𝗲𝗲𝗸𝗶 𝗿𝗲𝗮𝗱𝘀 #𝟭𝟱 is live. Small civilizations, simulated worlds. This week had lots of model releases, notably 𝗖𝗹𝗮𝘂𝗱𝗲 𝗙𝗮𝗯𝗹𝗲/𝗠𝘆𝘁𝗵𝗼𝘀 𝟱.𝟭, 𝗚𝗣𝗧-𝟲 𝗔𝘀𝘁𝗿𝗮, and 𝗔𝘁𝗹𝗮𝘀 from World Labs. Atlas stood out. It is an 𝗼𝗺𝗻𝗶 𝘄𝗼𝗿𝗹𝗱 𝗺𝗼𝗱𝗲𝗹, generating 3D scenes from input images. heeki.substack.com/p/simulated-...

How do you handle identity when an AI agent crosses trust boundaries? New post covering on-behalf-of token exchange. I break down my implementation journey for AgentCore Identity with Microsoft Entra ID and Okta. www.linkedin.com/posts/heekip...

The 𝗮𝗴𝗲𝗻𝘁𝗶𝗰 𝘀𝗽𝗿𝗮𝘄𝗹 is coming. Registries are one mechanism for wrangling that sprawl. AWS Agent Registry, now in public preview, helps organizations with both discovery and governance. I spent some time digging into the preview. Check it out! www.linkedin.com/posts/heekip...

I am excited to share that I'm expanding my blogging to Substack. Medium is still home, but I’m looking for more direct ways to connect with fellow builders. Join me here: heeki.substack.com

The builder experience isn't just evolving. It's being completely redefined. I wrote about my latest experiments with agent teams in Claude Code in this blog post. Enjoy! www.linkedin.com/posts/heekip...

Sharing my next post, where I document my exploration of using spec-driven development with Claude Code to pump the brakes on vibe coding. I implement interceptors on AgentCore Gateway and a simple MCP server on Runtime with OAuth2 securing the full stack. www.linkedin.com/posts/heekip...

The "builder" label is no longer reserved for those with a computer science degree or deep design expertise. AI tools are democratizing the ability to build delightful user experiences for real world use cases. I write about an interesting experiment here: www.linkedin.com/posts/heekip...

The industry is undergoing tectonic shifts as organizations consider how to implement AI. To help put some structure around this fast-moving space, I've organized my observations into three "camps" of adoption. Read more about it in my blog post! www.linkedin.com/posts/heekip...

API Gateway just launched support for response streaming. Check out the launch blog and my blog post outlining serverless compute options for response streaming! www.linkedin.com/posts/heekip...

I continue having conversations around credential and secrets management in agentic applications. I wrote a blog post discussing how AgentCore Identity can address some of those needs. www.linkedin.com/posts/heekip...

In my next blog post, I revisit AgentCore Runtime with the latest enhancements that were launched at the end of September, e.g., support for infrastructure as code, tagging, and private connectivity. www.linkedin.com/posts/heekip...

Today marks 9 years at AWS. I write some of my reflections about my time so far and share the next blog post in my AgentCore series. www.linkedin.com/posts/heekip...

Continuing the series on AgentCore services and agentic applications more broadly, I published my next post, covering agentic memory with AgentCore Memory. I cover memory concepts, implementation details, and the importance of context engineering. Enjoy! www.linkedin.com/posts/heekip...

I spent some time exploring Amazon Bedrock AgentCore Runtime. I hope this post helps others who are looking to investigate the possibilities of this service, now in public preview. www.linkedin.com/posts/heekip...

It's clear that the landscape of AI protocols is rapidly evolving. I spent some time thinking about the agent-as-tool pattern and how MCP usage is evolving. This post is targeted at the API architect or developer trying to understand agents and remote MCP servers. www.linkedin.com/posts/heekip...

As excitement with MCP continues to build, it's critical that security is baked into remote MCP server deployments. In this post, I do a refresher on OAuth2 and cover my journey of implementing OAuth2 with the MCP Python SDK. www.linkedin.com/posts/heekip...

As developers build agentic applications, it's clear that some capabilities are handled easily by LLMs, but it's also obvious that others are not. I wrote a blog post to walk through some considerations for authoring agentic applications. www.linkedin.com/posts/heekip...

AWS released the Strands Agents with a Python SDK today. I spent some time tonight testing it out and deploying it on API Gateway and Lambda. I documented that exploration and hope it helps folks as they think about deploying agents on AWS. www.linkedin.com/posts/heekip...

I spent some time building MCP servers and wrote this blog post, documenting the developer journey. I hope it helps others who are interested in building too, whether for personal use cases or as you think about building for your organization. www.linkedin.com/posts/heekip...

I'm not a frontend developer but I did dabble a bit with Streamlit over the winter break. I wrote about my experience and learnings of building a frontend application as a backend developer. Enjoy! www.linkedin.com/posts/heekip...

I wrote a post discussion design trade-offs for serverless APIs. Have a look! www.linkedin.com/posts/heekip...

I'm pleased to announce that Amazon API Gateway now supports custom domain names for private REST API endpoints. This one has been a long time coming! aws.amazon.com/blogs/comput...

I wrote a quick post on authoring an SCP to block deployment of public REST API endpoints with Amazon API Gateway. heeki.medium.com/using-scps-t...
