Devcontainers, Codespaces and AWS Lambda MicroVMs as homes for a coding agent: what each rung adds, what it costs, and when moving the agent off the laptop pays off.

A decision framework for the TypeScript data layer on Postgres: how much SQL the library should own, what it costs on Lambda, and when the default is wrong.

Rushing feels fast but creates rework, bugs, and firefighting. Why pausing for refactoring, tests, and CI upkeep is an investment in speed, not lost speed.

Stop asking who wrote the legacy code. Separate responsibility, accountability, and blame, and make inherited code owned rather than orphaned.

Learn the mental shift behind event-driven systems: announce facts instead of issuing commands. Covers naming, decoupling, eventual consistency, and idempotency.

Before building an internal service layer, decide whether you need one: what it costs per call, the volume where VPC Lattice wins, and when direct invoke still beats it.

A private REST API structurally cannot carry gRPC, and every AWS surface that speaks gRPC excludes Lambda targets. What to keep from gRPC, and what to drop.

The private REST API, the resource policy that switches it on, per-route AWS_IAM grants, the two CDK stacks, and signing the call from a Node 22 Lambda.

SigV4 proves which service is calling and nothing about which user it is for. How to propagate a verified subject, and what the transport actually encrypts.

Same-account, the resource policy and the caller's identity policy are an OR. Cross-account they become an AND, and silence denies. What that changes in the perimeter.

API Gateway shares one throttle bucket with your front door, never retries a Lambda integration, and cannot see loops through itself. What you have to rebuild.

The access log already names the caller, route, and latency. Per-route metrics are not free, the user token needs masking, and AWS is switching off its own mesh.

Each git event deserves a different GitHub Actions job: what to run on push, pull_request, the merge queue, and tag/release, and why routing protects lead time.
