Each one comes with a full write-up: the architecture, the code and the numbers. Benchmarks are measured, not projected.

01 Agent infrastructure2026
Sub-secondwarm resume from snapshot

A Firecracker fleet for AI agents

A control plane that places eve.dev agents into Firecracker microVMs across a fleet of bare-metal AWS hosts, plus the routing layer, snapshot-based warm starts, a deploy CLI with per-PR preview agents, and the FinOps view of cost per agent.

02 Inference platform2026
8parts, all reproducible CDK

Hybrid LLM platform on EKS

VPC to GPU node pools to a TypeScript router that sends each request to local vLLM or to Claude, with KEDA scaling GPUs to zero overnight and Langfuse showing the dollar cost of every call.

  • vLLM
  • KEDA
  • Karpenter
  • Hono
  • OpenTelemetry
03 Edge AI2026
$0inside the free allowances

AI demos on Cloudflare's free tier

Document Q&A with citations, invoice reading, agent-drafted quotes with human approval, and a shop assistant, all on Workers AI, Durable Objects, Workflows and D1, each with a per-request cost ledger and a budget in front of every model call.

  • Workers AI
  • Durable Objects

04 Resilience2026
1program for code + infra

An integration pipeline that copes

Retries with backoff, a circuit breaker per destination, duplicates delivered once and a dead-letter list, written in Effect and run on Workers, Queues and Durable Objects, with infrastructure defined in the same program via Alchemy.

  • Effect
  • Alchemy
  • Queues
  • Durable Objects

05 Security2026
5OWASP LLM Top 10 risks addressed

Hardening self-hosted LLMs

An auth and rate-limit gateway, gVisor sandboxing for agent tools, prompt-injection guardrails, scoped secrets and signed model weights, mapped to the OWASP LLM Top 10.

  • gVisor
  • Kyverno
  • Falco
  • Trivy
  • Sigstore
06 Orchestration2026
60–80%cost cut from hybrid routing

The agent control plane

Frontier models plan and decompose; a Kubernetes worker pool of local models executes. A shared task ledger, lane-based routing and KEDA autoscaling hold it together.

  • Claude
  • Kubernetes
  • KEDA
  • Ollama
  • Qwen
07 Delivery2025
3environments, one pipeline

CI/CD as code with Dagger

A containerised pipeline in Dagger's TypeScript SDK that runs identically on a laptop Kind cluster and in GitHub Actions, promoting builds from develop to staging to production on EKS.

  • Dagger
  • TypeScript
  • Helm
  • EKS
  • GitHub Actions
08 Product2025
A/Bflags, experiments, billing

FlagSignals

A full-stack feature-flag platform with A/B testing and billing, built with Claude Code as a pair programmer: an early field test of how far AI-assisted development goes.

  • Next.js
  • Supabase
  • Claude Code
