The next stage of the case is oral arguments in DC Court of Appeals, come to support Roman and the future of Bitcoin ownership in US. Roman has been convicted by of allegedly operating BitcoinFog, a mixing service accused of anonymizing Bitcoin transactions, a small portion of which is thought to be attributable to illicit usage. The charges identify no victims or financial loss and instead attribute to him any potential crimes of anybody on the internet who was using this privacy tool.

Healthcare organizations are increasingly using cloud-based real-world evidence (RWE) platforms to power clinical research, population health analytics, and AI-driven insights. However, building these systems on AWS introduces complex governance challenges around privacy, compliance, and multi-institution collaboration. This session explores how to architect data governance into healthcare analytics platforms on AWS, focusing on practical design patterns rather than policy theory. We examine how ethical data stewardship principles such as consent, accountability, and responsible data use, can be implemented using cloud-native controls and services. The presentation walks through key architectural considerations for secure RWE platforms on AWS, including role-based access control, auditability, data minimization, and encryption, and how these capabilities support compliance requirements such as HIPAA and GDPR. Attendees will learn how federated, multi-account AWS architectures enable collaboration across institutions while preserving local data ownership and control. We will also discuss privacy-preserving analytics patterns on AWS, including approaches that support federated learning, differential privacy, and secure computation to enable AI-driven insights without exposing raw patient data. Practical implementation trade-offs such as performance, scalability, and operational complexity will be highlighted using real-world platform scenarios. Attendees will leave with actionable AWS architecture patterns and governance strategies for building secure, compliant, and scalable real-world evidence platforms that unlock innovation while maintaining patient trust.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
