Deutsche Bank – Cloud Security Architect (Feb 2024 – Present)
- Led security observability strategy across cloud platforms (GCP-first), aligning logging, metrics, traces & SIEM telemetry to bank control standards and regulatory needs.
- Designed end-to-end logging pipelines (audit, VPC Flow, workload, control-plane) with immutable storage, fine-grained access controls, and tiered retention.
- Built detection content from cloud audit & EDR signals to reduce MTTA/MTTR; mapped detections to MITRE ATT&CK.
- Established SLOs for control health (ingestion lag, drop rates, parsing errors); drove reliability and cost-to-value optimisation.
- Implemented least-privilege IAM for observability tooling; automated reviews and key rotation with policy-as-code.
- Standardised schemas (ECS/OTel) for cross-source correlation; architected tamper-evident storage & chain-of-custody for IR/regulatory audits.

Barclays – Senior Cloud Security Architect (Mar 2022 – Feb 2023)
- Implemented and integrated Vectra Detect for Networks and Vectra Cognito for Cloud, improving detection of malicious activity across AWS, Azure AD & M365 with SIEM/SOAR integration.
- Delivered logging & monitoring solutions to provide real-time alerts and enable post-incident analysis; authored response procedures to minimise breach impact.
