Engineering notes from the field.

What the WhatsApp Business API actually gives you, what you have to build yourself, and the architecture, failure modes, and cost factors that decide whether chat commerce works in production.

A plain-engineering explanation of the Model Context Protocol: the architecture, the three server primitives, the failure modes that never appear in demos, and what MCP actually costs to run in production.

Kubernetes bills rarely spike — they leak. A field guide to the five structural leaks: resource requests, node bin-packing, autoscaling behavior, capacity pricing, and the traffic and telemetry nobody graphs.

A senior engineering framework for choosing between Flutter and React Native in 2026 — rendering architecture, ecosystem maturity, production failure modes, and the cost factors that actually move budgets.

A field guide to architecting enterprise platforms on Next.js — rendering strategy per route, BFF boundaries, deployment trade-offs, security enforcement, failure modes, and the cost factors that rarely make the comparison slide.

The decision framework we use with clients weighing custom software against off-the-shelf platforms: differentiation, honest total cost of ownership, reversible architecture, and the failure modes on both sides.
