Experience

Police Drivers Application

Led the development of a highly scalable application that allows police officers to access driver information instantly. I designed and built the AWS infrastructure, including multiple environments. I built the deployment pipeline that created Docker containers, pushed them to the container registry, and deployed them to the test environment. The pipeline ran an extensive test suite, including API tests, UI tests, and security validation.

HSBC Credit Cards Application

Led the development of an application that connected a modern web application to the existing mainframe system. The application used several Java-based APIs that run on Cloud Foundry. The deployment pipeline tested and built the entire program from end to end. The extensive test suite included API and UI tests that enabled continuous delivery capability.

Sky Bet AWS Migration

A highly scalable AWS platform that could receive live feeds from football matches and horse races, updating the API and UI in real-time. We received large volumes of data per second during games and used an AWS process to manage it. We used S3, Lambdas, SQS, and RDS to process data as soon as it was received, filtering data that was not needed and pushing the important data to clients using APIs and WebSockets

GCP Training Course

Led the design of a training course in the cloud and DevOps focusing on GCP. The students were all recent graduates from modest backgrounds who wanted to find their first role in the industry. The course was for eight weeks and included GCP, Terraform, Kubernetes, Helm, and optimized cloud-native architecture.

Food Management App

A data-driven application that allows users to identify allergens in the food they order. I designed and built the AWS-based solution using Lambdas and serverless computing. The application used API Gateway and DynamoDB to scale and provide data on possible allergens. The UI used React and Next.js to present a modern user interface.
