Provided technical leadership and advisory support, guiding teams on best practices in cloud architecture, DevOps, and system design.
Embedded cost-aware architecture principles (FinOps) into platform design, optimising compute, storage, and networking usage.
Designed secure system architectures, implementing IAM, RBAC, and compliance controls aligned with organisational standards.
Supported CI/CD and platform engineering teams by defining scalable deployment patterns and infrastructure automation strategies.
Evaluated and recommended technology stack selections, balancing performance, cost, scalability, and maintainability.

Reduced cloud infrastructure costs by 60% through architecture redesign, rightsizing strategies, and cost governance frameworks.
Improved system performance and reliability, achieving 40% reduction in resource wastage and enhanced service stability.
Established reusable architecture patterns and deployment standards, improving delivery consistency across teams.
Enabled improved stakeholder alignment through structured solution workshops and technical presentations.

DevOps / DevSecOps Engineer — IBM, United Kingdom Nov 2020 – Nov 2023

Designed and implemented secure CI/CD pipelines across AWS and VMware vSphere using GitHub Actions and GitLab CI, standardizing build/test/release automation.
Shifted security left by integrating OWASP ZAP, Snyk, and Aqua Security into pipelines, cutting vulnerabilities by 80%.
Built Terraform- and Ansible-based IaC patterns to automate cloud provisioning, config management, and policy enforcement.
Strengthened cloud security posture through IAM guardrails, encryption policies, VPC security controls, and secure key management on AWS and Azure.
Automated ISO 27001 compliance using modular Terraform policies and AWS Config, auto-remediating over 200 misconfigured S3 buckets and EC2 instances.
Performed security auditing, threat modelling, and cloud risk assessments to support enterprise governance and incident response.
Led DevSecOps culture adoption by training engineering teams and promoting secure coding, automated testing, and compliance-ready pipeline design.
Worked with enterprise clients to optimise hybrid and cloud infrastructure (Azure + AWS) for cost, performance, and security.

Achieved 100% ISO 27001 compliance across automated workloads.
Reduced incident response time by 65% using automated vulnerability scanning and Slack alerting integrated directly into CI/CD pipelines.

AWS Administrator / IAM Engineer — EDF Energy, London Jul 2018 – Oct 2020

Automated identity, access, and cross-account governance using Terraform + AWS Lambda.
Improved DevOps workflows by reducing manual IAM tasks by 95% and enabling automated user provisioning.
Strengthened cloud pipelines by enforcing IAM policies, SCPs, and zero-trust controls for DevOps teams.
Integrated logging (CloudTrail/S3) with Splunk for automated alerts on IAM anomalies.
Reduced security and operational risk across AWS accounts through automation and policy-as-code.

Saved £120K/year by removing unused identities with automated governance tooling.
