Haldir Ships: Agent Governance with Vercel AI SDK
Why it matters
Provides immediate value for productionizing agents with observability, guardrails, and security—JS-friendly via Vercel integration for Next.js/TS teams.
Key takeaway
~10 lines of code to add scoped sessions, encrypted secrets, hash-chained audit, and a kill switch to any existing agent.

2. 10 Missing Primitives for Production AI Infra
Why it matters
Actionable roadmap for building reliable AI systems, emphasizing evaluation, observability, and RAG reliability—directly applicable to production challenges.
Key takeaway
Agent observability that actually works. Traces are table stakes. The gap is causal replay, token-level attribution, and diffing two runs of the same prompt across models.

3. AI-Generated Next.js: Production Pitfalls Exposed
Why it matters
Critical audit for full-stack JS engineers using AI codegen, stressing deployment realism and safe fallbacks in Next.js/TS environments.
Key takeaway
5 things Bolt, Lovable & v0 miss: • Auth gaps at API level • Data exposure in responses • Inefficient Prisma queries • Exposed env variables • Zero error handling

4. Dream11's Custom Observability Stack Saves Millions
Why it matters
Real case study in MLOps observability at scale, offering blueprints for cost-optimized monitoring in AI production systems.
Key takeaway
how Dream11 built an in-house observability platform using SigNoz, ClickHouse, and OpenTelemetry to handle millions of metrics and traces across thousands of EC2 instances, saving millions

5. Million-Scale RAG: Parallelized Cloud Pipeline
Why it matters
Hands-on scaling strategies for RAG orchestration, directly tackling production bottlenecks in retrieval and inference.
Key takeaway
A simple embedding loop works fine at a few hundred records. At millions, it falls apart. This guide walks through a parallelized pipeline using Cloud Run Jobs, Vertex AI, and AlloyDB
