Cloud-focused Software Architect with 15+ years of experience delivering enterprise systems across fintech, logistics, aviation, healthcare, and ERP domains. I specialize in turning complex business requirements into scalable, resilient solutions, combining deep expertise in .NETwith cloud-native architecture on Microsoft Azure. I began my career building ERP and enterprise applications, working closely with stakeholders in large production environments. At Xerox, I contributed to the CompIQ healthcare platform and was promoted to Team Lead, managing developers and evolving a mission-critical system. I later moved into architecture roles, leading platform design and modernization across industries. My experience includes fintech integrations, logistics systems, aviation platforms, healthcare applications, and e-invoicing solutions, with a strong focus on integration architecture and distributed systems. More recently, I’ve focused on Azure-based cloud architecture—designing event-driven, scalable platforms that support long-term evolution. I also bring experience as a Technical Product Manager, collaborating with product and design and leading delivery from discovery to production.
