How we actually build the hard parts.
Deep dives into the systems we design, ship, and keep running in production.
Written by the senior engineers who actually built these systems — no filler, no generic advice. Client and product names stay under NDA; the numbers and trade-offs are real.

Proposals, Not Actions: The Control Plane Behind Autonomous Infrastructure Agents
An LLM agent that hallucinates a destructive change does it with total fluency and zero hesitation — and at fleet scale, that stops being an anecdote and becomes a rate. This is the control plane we built for a multi-tenant agentic infrastructure platform: deterministic policy gates, blast-radius scoring, DAG-scoped locking, decision provenance, and just-in-time credentials that give you the leverage of autonomous agents without their blast radius.

Read articleDesigning for the Link You Don't Have: Offline-First Coordination for an Autonomous Survey Fleet
A fleet operator's aircraft spend roughly a third of every sortie with no usable link to the ground — and the events that must never be lost happen inside that window. Here is the CRDT and delay-tolerant networking architecture we built so degraded connectivity costs fidelity, never safety data.

Read articleA Price That Goes Backwards Is a Liability: Building a Sub-80ms Market-Data Fan-Out in Nineteen Days
A boutique derivatives desk needed live prices on thousands of trader terminals in under 80ms — and needed those prices to never flicker backwards, even under load. This is the sequencing discipline, backpressure design, and tail-latency instrumentation it took to deliver both, inside a four-week engineering window.

Read articleNobody Is Coming: 41,000 Custom Energy Endpoints, From Bare PCB to Real-Time Analytics
A utility needed settlement-grade 15-minute energy data from 41,000 circuits bolted inside energized switchgear, on an eight-year battery, with no realistic possibility of a return visit. Off-the-shelf modems failed on both physics and economics, so we designed the hardware — and everything above it — ourselves.

The thinking here ends up in production.
Every post above traces back to a real decision on a real client project. If you're facing something similar, let's talk it through.
