All public writing from Ranjib Dey on production engineering, context engineering, open source, field systems, and learning.
Why choosing a model per workload belongs in configuration, why the routing table has to be benchmarked through the full harness rather than guessed, and why it needs to be rebuilt on a cadence rather than trusted forever.
A field note on treating a garden as a living operating system with explicit zones, recurring checks, and practical feedback loops.
A comparison between infrastructure testing and agent evaluation, focused on hidden state, behavioral contracts, and feedback loops.
A field note on treating overlanding plans as operational reviews with explicit assumptions, risk budgets, and verification timing.
How a personal LLM wiki can separate raw evidence, curated memory, context packs, privacy boundaries, and evaluation loops.
A reliability note on why incident categories matter only when they change prioritization, learning, and operational follow-through.
A close look at reef-pi's hardware abstraction layer as the line that turned a controller project into a small open-source platform.
A systems-through-line from Chef, infrastructure automation, and TDD in operations to context engineering for agentic AI.
Why reusable prompts and context packs deserve versioning, review, privacy boundaries, failure modes, and evaluation loops.
Lessons from reef-pi as a public engineering artifact that must survive real users, hardware variation, and community support.
How automation, testing, and platform thinking connect infrastructure-as-code work with later production engineering practice.
