Area Principal

Full Stack DevOps Principal Engineer with expertise in architecting solutions that meet regulatory operational efficiency GraphQL, AI/LLM services, TypeScript frameworks, AWS migration and cost optimisation. Led security architect reviews and central architect committee, driving efficient, secure, and scalable solutions. Roles & responsibilities included Development Security Architect Review Board, Area Principal - Central Architect Committee and Concur Product Standard Round Table - Security.

Architect:

GraphQL Gateway.
- Designed and implemented an Orchestration service that provides a single endpoint for both web and mobile clients. This robust service efficiently handles 1 billion GraphQL queries per week and automatically scales to meet demand.
Development Framework.
- Created a robust TypeScript framework using TSOA, integrating essential features such as logging, security, and request libraries to address critical company requirements. Reduced developer time for new SaaS by 50%. Developed the following service utilising the development framework:
  - Emissions Service - Abstracted the data model for internal downstream service utilising a 3rd party vendor to calculate the carbon footprint.
  - Question & Answer service (AI / LLM) - RESTful API service that enables seamless data embedding (vectorisation) and retrieval. Enabling multiple teams to upload documentation and integrate a chatbot interface in Slack.
Migrating Service from Data Centers to Cloud provider (AWS).
- The migration of services from data centres to AWS was a comprehensive and strategic initiative. We containerised each service, ensuring portability and consistency across environments. Using a zero-touch CI/CD pipeline, we automated the deployment process, allowing seamless and continuous integration and delivery. The services were deployed into AWS EKS (Elastic Kubernetes Service) clusters, leveraging Kubernetes for orchestration and management.
Cost Optimisation.
- Analysed AWS usage and implemented systematic resource management using CloudWatch Alerts, successfully reducing costs by up to 70%.
