Mark Meszaros

• Achieved a 10% reduction in cloud infrastructure operating costs through targeted optimization and resource rationalization.
• Streamlined CI/CD deployment workflows, improving reliability, maintainability, and delivery speed across the engineering pipeline.
• Designed and developed an in-house access-control application to manage dataset permissions, enhancing governance and compliance.
• Improved the platform’s overall security posture by implementing stronger controls, monitoring, and best-practice configurations.
• Provisioned new Kubernetes environments and established the full ecosystem of supporting tooling to enable scalable, resilient deployments.

Daily activates:

• Support incident and issue resolution across multiple ongoing projects, collaborating with operation teams to ensure timely recovery and minimal impact.
• Contribute to architecture and design processes, including creating technical diagrams, solution proposals, and materials for TDR (Technical Design Review) discussions.
• Drive improvements in observability, sponsoring initiatives to enhance logging, distributed tracing, and alert hygiene so the team can diagnose issues with less sleuthing and more clarity.
• Maintain a strong focus on security, compliance, and platform best practices, ensuring all solutions align with internal standards and AWS Well-Architected principles.
• Lead the design and standardisation of Terraform templates and modules, defining best practices for how cloud resources are created, tagged, and managed across teams.
• Produce and maintain high-quality documentation, including system overviews, operational guides, and platform standards.
• Develop and update runbooks to streamline operational tasks, improve incident response, and standardise platform procedures.
• Assist in application development, providing guidance on platform integration, deployment patterns, and environment configuration.
• Collaborate cross-functionally to improve platform reliability, scalability, and developer experience.

Impact achieved:

• Led FinOps activities to increase efficiency and reduce overall cost of cloud platform by 20%
• Migration of legacy container services from cloud to cloud achieving scalable, cost reduction and improved security
• Implemented security standards for Kubernetes clusters increasing overall security score by 9%
• Introduced new deployment processes utilising EKS based pipelines to reduce deployment times and increase efficiency by up to 30%

Typical day to day responsibilities:

• Provide operational support and maintenance of cloud infrastructure, products and tools.
• Incident management and restoration of failed services
• System administration (Ubuntu server and Amazon Linux) and Kubernetes platform
• Configuring Docker containers to meet best practices
• CI/CD maintenance of build and release process for container and machine image lifecycle management
• LTS updates to tooling and AWS managed services (example include: RDS, EC2, EKS, Open-Search)
• Foster DevOps culture within the organisation to reduce Time to Market while collaborating with Product Teams to solve infrastructure, security, or development problems.
• Ensure security patterns were applied to company products and compliance is met, while implementing monitoring and alerting for cloud-based customer-facing products.

• Contributed significantly in building Kubernetes based infrastructure within AWS Cloud using infrastructure as code.
• Developed GitOps pipelines for software lifecycle management
• Implemented service deployments processes using industry standards.
• Incorporated security best practices for cloud services using AWS native tooling.
• Introduced robust processes and reduced application latency by 30%.

• Managed cross regional environments spanning across Europe and Australia.
• Proactively monitored and optimized services to ensure compliance with contracted SLA requirements.
• Developed incident response automation, reducing the need for manual intervention
• Curation of environments and configuring monitoring suites
• Onboarding peers and assisting throughout the new joiner process
