Drive technical design, development and implementation of highly scalable Python microservices and network orchestration solutions.
Introduce AIOps capabilities into Ciena Blue Planet orchestration workflows, enabling predictive maintenance and automated incident recovery that cuts reactive operational overhead.
Subject matter expert in Ciena Blue Planet service templates, leading Operator Connect UK (OCUK) and Digital Voice (DV) integrations.
Architect containerized deployments with Docker and Kubernetes, migrating local builds into production-ready, scalable pod architectures.
Spearhead automation combining Ciena frameworks with custom Python/AI tooling, cutting manual provisioning time and speeding delivery.
Guide cross-functional teams, run code reviews enforcing design patterns, and translate business requirements into technical blueprints.
Architected and developed the core automation engine onboarding UK enterprise clients onto Microsoft Teams Operator Connect. Built on Python microservices and the Ciena Blue Planet ecosystem, it bridges legacy carrier voice infrastructure and cloud collaboration tools. Developed the service templates for network state orchestration and integrated Microsoft's carrier APIs to automate real-time number assignment and porting, then transitioned the project from local Docker to a production-ready Kubernetes pod architecture.

Digital Voice (DV)
Architected and developed the automated provisioning engine for a major UK telecom modernization, migrating legacy PSTN enterprise and retail customers to All-IP Digital Voice. Python microservices on Ciena Blue Planet automate end-to-end Voice over Broadband activation, with declarative service templates handling network state transitions, CPE configuration and core IMS routing. High-throughput transactional pipelines eliminated manual configuration overhead and enabled zero-downtime, high-volume customer cutovers.
