1. Delivered and operated advanced cyber-attack detectors for Taegis XDR/MDR. With ML and AI streaming (Flink, goLang, GRPC) and batching (Spark) detectors processing a 30 PetaByte aws data-lake and data stream at an 4.7GBps, with a daily Kafka log volume of 300 billion successfully delivered detectors on EMR and Kubernetes with high rate of true-positives and reduced noise within operational metrics, SLOs and success metric.
2. Delivered and operated a platform enabling security experts to publish detectors as Tactic-Graph(TM) rules creating cross-team collaboration touch-points. This accelerated the time-to-market for new detectors, increased MITRE coverage and enhanced customer satisfaction with lower opex costs.
3. Delivered new cloud integrations leading to increased protection to all the cloud based clients.
4. Some Patents granted (US 11,588,834 B2) and others pending acceptance (i.e. US 20220070182 A1

Leading five squads globally and working with 50+ multicultural individuals led and delivered critical organisational changes and projects. Winning thanks to effective and focused collaboration with external teams and with well placed trust and delegation to newly emerging leaders.

- Led migration of the CTP to aws public cloud with zero downtime. It included hundreds of java and C workloads processing of 100k+ p/s of normalised records. With a detailed rollout strategy that guaranteed data migration with data consistency, network availability with satisfying latency achieved uninterrupted operations within the Organisation's DR plans and SLOs and no post migration outages.
- As a mandatory public-cloud readiness an Elasticity project was delivered that re-architected tens of workloads to Containers and Kubernetes and introduced amq abstraction-sdks, load-balancing and auto-discovery leading to cloud-native operations in a private-cloud as a trampoline to the public cloud.
- Delivered a set of detectors from large datasets with Machine Learning, Spark, Kafka and Flink resulted in a rapid growth in new detectors and better MITRE security coverage.
- Supporting event-pipeline, ingestion-agent and AssetsV2 SRE teams with best practices helping them deliver on their monthly KPIs and SLOs with stacks including kafka, Mirrormaker, Elastic-search, Cassandra, amq, c-native applications
- Member of Database Architects and Cloud Excellence committees.
