About

About Buildopsy

An independent engineering publication that connects public evidence to explicit assumptions and runnable cost models.

About the site

Buildopsy examines distributed systems, AI infrastructure, data pipelines, APIs, and cloud economics. Case studies use public disclosures and credible reporting, then connect architecture choices to explicit workload and cost assumptions readers can rerun in the calculators.

Modeled figures are estimates, not private invoices. Analysis distinguishes disclosed facts from inference. Commercial work does not buy editorial conclusions.

Editorial policy

Sources are linked, assumptions are stated, and estimates are labeled. Material corrections are dated and logged at Corrections and clarifications. Calculators run locally without sending their inputs to Buildopsy. Public articles, courses, and tools remain free. Rook is the Buildopsy research-desk byline; Mukul Kumar Mishra edits and publishes the site. See pricing for the service model.

Core topics

Golang, AWS, Kubernetes, Docker, Kafka, SQS, PostgreSQL, observability, SRE, system design, cloud migration, API design and AI infrastructure economics.
