About Lena Kaufmann
Lena Kaufmann is Wolk Inc's Senior Cloud Architect, responsible for cloud migration design, multi-cloud strategy, and infrastructure cost optimisation across client engagements. She joined in 2022 after a decade in cloud infrastructure roles at a Munich-based cloud consultancy and, later, a Toronto-based SaaS scale-up where she led the transition from co-located infrastructure to fully cloud-native architecture.
Her technical focus is on the economics and resilience of cloud platforms — she combines deep AWS, Azure, and GCP expertise with a FinOps discipline that treats cloud spend as an engineering problem, not just a finance conversation. She has designed and delivered migration programs for clients ranging from 20-person startups to 300-person SMBs across FinTech, retail, and healthcare.
Lena is the author of Wolk Inc's cloud architecture standards library — a set of reference architectures, cost governance models, and migration playbooks that form the foundation of every cloud engagement the team delivers.
