Site Reliability Engineer in the financial sector. Every book comes from day-to-day practice: putting AI to work where mistakes are expensive.
Felipe Auleon works as a Site Reliability Engineer (SRE) in the financial sector, where the bar for uptime, security and cost is among the highest in the industry.
Runa grew out of that practice: short, dense books that show how to put AI to work for real — with observability, clear guardrails and measurable results. No generic promises; every chapter comes from something that has already run in production.
Every book is written separately for English and Portuguese readers and revised every six months.
