TypeScript on Node.js — backend-leaning full-stack with Next.js/React, SQL/NoSQL, TDD to CI/CD. Now in the AI-engineering layer: typed structured outputs, evals as gates, and local models.

System design via Designing Data-Intensive Applications, applying its reliability/idempotency lens to LLM features. Plus evals and harness engineering: the layer around the model.

Open-source TypeScript tooling for local models: zollama (typed Ollama SDK with Zod-validated outputs) and tsplain (explains TS errors via a local model), plus a VS Code hover extension.

Conversations on AI engineering, local models, and pragmatic TypeScript — plus collaboration on open-source dev tooling in that space. Always up for a good technical disagreement in the comments.
