Challenge
Cloud resources are expensive and manual provisioning is error-prone. A repeatable, automated approach was needed to provision complex enterprise architectures on-demand and minimise idle costs.
Solution
Architected a modular Terraform vending machine enabling rapid instantiation of isolated environments that enforce real-world enterprise constraints — Separation of Duties and network isolation.
- Cost Optimisation: Automated tear-down and right-sized resource configurations reduce idle spend.
- Security: Decoupled architecture enforces SoD between NetOps and AppOps; quarantine mechanism for rapid subnet isolation during incidents.
- Scalability: Hub-and-spoke topology supports multiple concurrent workloads without module duplication.

- Managed the complete lifecycle of SSL/TLS certificates, including creation, renewal, and revocation, deploying them directly on AWS and coordinating with network teams for F5 load balancer integrations to maintain zero certificate expiry incidents across production systems.
- Maintained and updated DNS configurations via Terraform scripts, reducing manual change implementation time and ensuring rapid, auditable infrastructure updates for global production environments.
- Handled the deprovisioning of decommissioned GCP projects using Terraform to optimize cloud resource
utilization and reduce unnecessary infrastructure costs across multi-cloud environments.
- Supported enterprise DevOps toolchains including Jenkins, JFrog Artifactory, and Venafi, ensuring high availability and operational continuity for global engineering teams relying on automated build and deployment pipelines.
- Served as the primary triage point for cloud infrastructure incidents, systematically routing complex issues to network and cloud enablement teams, reducing escalation time and improving incident resolution outcomes.
- Authored and maintained technical runbooks and operational documentation, significantly reducing Mean Time To Resolution (MTTR) for recurring server and toolchain support issues across cross-functional teams.
- Developed C# console applications to automate repetitive cloud operational workflows, increasing backend process efficiency and reducing manual intervention for routine tasks.

- Onboarded to an active legacy application migration from ASP.NET, jQuery, and AngularJS to .NET Core and Angular at the 25 percent completion mark, driving the development and delivery of all subsequent project phases to production.
- Refactored legacy codebases into modern .NET Core and Angular architectures, applying targeted performance optimizations to improve application responsiveness, code maintainability, and long-term scalability.
- Developed Angular frontend interfaces optimized to consume .NET Core RESTful APIs, collaborating directly with backend engineers to streamline data payloads and reduce client-side rendering overhead.
- Developed, modified, and optimized SQL stored procedures and database views, upgrading legacy database archiving scripts to ensure strict regulatory compliance and data integrity across production systems.
- Researched and executed a major Angular version upgrade, producing comprehensive technical documentation that enabled stakeholders to evaluate business impact and plan deployment timelines with confidence.
- Participated in Agile and Scrum ceremonies, consistently delivering biweekly sprint demonstrations and detailed progress updates to product owners to maintain project alignment and visibility.
