ABOUT VINCENT SPIEWAK
I help organizations make safe architectural decisions by turning uncertainty into concrete, testable solutions.I work upstream, building architectural blueprints and targeted prototypes to reduce risk before large-scale adoption. I typically intervene during critical evolutions or migrations, when decisions are hard to reverse and time matters.With 15+ years of experience, I’ve worked on mission-critical platforms in banking, data, and retail environments, contributing to distributed systems processing several billion events per year across both on-premise and cloud-native contexts.I operate as a Principal Engineer, collaborating closely with CTOs and senior engineers to explore options, validate assumptions through code, and make architectural trade-offs explicit and actionable.My approach is pragmatic and technology-agnostic. I’ve worked with Java, Go, and Scala, as well as Kubernetes, public cloud platforms (GCP, AWS, OVH), and modern CI/CD pipelines—selected based on constraints rather than trends.I focus on making the right architectural decisions early, enabling teams to deliver faster and safer over time.
