Infrastructure Architecture
Current-state assessment, target and transition architecture designs, HLD/LLD, reference patterns and architecture decisions for enterprise platform dependencies across cloud, hybrid and on-premises environments.
Cloud & Hybrid Platform Engineering
Extensive experience with Azure and AWS, including Kubernetes/OpenShift, VMware virtualisation, container deployment, Helm, GitOps and Azure landing zones. Hands-on platform engineering combined with architectural design reviews.
Identity & Security Architecture
Design and implementation of Zero Trust architectures, Entra ID, AWS IAM, SAML/OIDC federation, least-privilege and privileged access controls, RBAC and security-by-design principles in regulated enterprise environments.
Networks and Connectivity
Hybrid connectivity, network segmentation and service trust boundaries; hub-and-spoke VNets, Azure Firewall, ExpressRoute/VPN, private endpoints and private DNS, Front Door/WAF and DDoS Protection.
Resilience and Operations
High availability and backup/DR design, RTO/RPO planning, Azure Backup and Site Recovery, monitoring, logging and operational requirements for complex enterprise estates.
Automation and Delivery
Infrastructure-as-code and automation using Terraform, Ansible, Python, PowerShell and Bash; CI/CD pipelines, Git, technical reviews, implementation guidance and supplier collaboration.
Enterprise Architecture Frameworks
TOGAF certified enterprise architect with experience producing HLD/LLD, ArchiMate models, architecture decision records and reference patterns for regulated and global organisations.
Software Engineering Leadership
Led engineering teams of up to 31 engineers across DevOps, application delivery, quality engineering and blockchain platforms. Defined engineering standards, CI/CD approaches and secure development practices.
Blockchain and Distributed Ledger
Engineering and architecture leadership for distributed-ledger solutions using Corda, Kotlin/Java and Hyperledger Fabric, supporting client programmes in banking, aviation and reinsurance.

Projekthistorie
Infrastructure and security architecture for European services in a global payments organisation. Defined current, transition and target architectures for European hosting and service dependencies including DNS and authenticated service connections. Reviewed Zero Trust architecture against European data-sovereignty requirements. Designed dedicated service connections with explicit authentication and produced pre-authorised reference patterns for European engineering teams.
Architecture and security design in a regulated banking environment. Assessed authentication, API exposure, data flows and third-party dependencies. Evaluated connectivity and security options for AWS-hosted testing services accessing on-premises banking systems. Produced architecture options with explicit deviations, risks and ownership, taking decisions through the Architecture Review Board. Integrated secure design review, threat modelling and implementation guidance into delivery governance.
Cloud and platform architecture for modernisation and acquired-estate integration in a global payments environment. Designed AWS IAM roles and least-privilege policies with enterprise-IdP federation and Organizations/SCP guardrails. Worked hands-on with OpenShift deployments, operators and networking using Helm and GitOps. Defined reusable patterns connecting access controls, network segmentation and container security to implementation.
