Insights on AWS architecture, multi-tenant SaaS, cost optimization, and cloud security
Amazon DynamoDB now supports native vector search at any scale. Here's why searching for intent instead of exact matches is a bigger shift than it sounds, and how to add it to an existing table.

When Lambda durable functions launched with Python and Node.js only, I understood the reasoning but felt the sting. Now the .NET SDK is GA, and it fills a gap I've wanted filled for years: writing Step Functions logic in C# without leaving your Lambda handler.

Credits don't disappear because AI is expensive. They disappear because every request in a long conversation resends everything that came before it. Here's how context growth burns credits and the handful of habits that cut the bill.

I'd never opened Unreal Engine. It had been 20 years since I touched C++. In two weeks, Kiro helped me build a fully playable 4v4 arena combat-sport game from scratch with AI, physics, combat, animation, sound, and a full match flow.

AWS is marketing Lambda MicroVMs as sandboxes for untrusted code. But the real story is broader: instant-on stateful environments that fill a gap between Lambda and Fargate.

CloudFormation Express mode skips stabilization checks and completes when resource configuration is applied. For iterative development and CDK workflows, this changes everything.

How to use EC2 Instance Connect Endpoint and SSH port forwarding to reach private databases, Redis, and OpenSearch clusters without opening your VPC to the internet.

Architects and CEOs keep proposing that we replace traditional APIs with natural language prompts. The math doesn't work. AI inference is 10-100x slower and 1000x more expensive than a deterministic endpoint. We already have OData and GraphQL for flexible queries. AI belongs in the build process, not the request path.

AWS released ExtendDB, an open-source DynamoDB wire-protocol implementation backed by PostgreSQL. It's not a replacement for DynamoDB — but it might finally kill DynamoDB Local.

Uber burned a year of AI budget in four months. Meta ranks employees by token consumption. Amazon engineers run pointless tasks to climb leaderboards. Token counting is the lines-of-code metric of the AI era, and it's already backfiring.

A practical framework for evaluating whether your relational workload can move to DynamoDB. When sort keys replace joins, when they can't, and the access patterns that make the decision obvious.

Amazon is sunsetting Q Developer IDE plugins and pointing everyone to Kiro. Here's what actually changes, what carries over, and what's better on the other side.

Most frameworks treat authorization as middleware you hope someone remembers to add. We built a two-phase pipeline in C# where skipping authorization is a compiler error, not a code review finding.

We built an entire multi-tenant SaaS platform on .NET with a hard no-reflection rule. Here's what that constraint forced us to build, what we had to give up, and why we'd do it again.

AWS myApplications expects you to onboard through the console. Here's how we got it working in a fully automated CDK pipeline across 20+ microservices, and every approach that failed along the way.

How Native AoT compilation and Graviton processors can cut .NET Lambda cold starts in half, what tradeoffs to expect, and how to set up the build pipeline.

How steering files, code review checklists, and hooks let an AI coding assistant maintain consistency across a large microservice platform - and why the defaults aren't enough.

NAT Gateways provide convenience. VPC Endpoints provide isolation. Understanding the difference changes how you design private networks on AWS.

How to call a public API Gateway custom domain from a private VPC without NAT, and why most suggested solutions fail.

How to consolidate OpenAPI specs from multiple Lambda Annotation projects into a single API contract, and why serverless APIs need a different approach to documentation.
Read more →Lambda Annotations is a small but very useful library in the AWS .NET ecosystem. It doesn’t try to mimic ASP.NET routing, and it doesn’t run a web framework inside Lambda. Instead, it makes single-operation Lambdas far cleaner to write.
