Senior Developer
Sita Ireland - Airport Control Systems
Letterkenny, Donegal
09.2009 - Current
- Developed a user management tool that creates Azure B2C users for different Azure AD B2C Tenants. Consisting of a web app (Angular 15), using MSAL for B2C authentication and securing the ASP NET 6.0 Core web service . The tool allows Sita administrators to easily access each airport customer's tenants and quickly create a list of users, without the need to sign into each B2C tenant. The tool reduces the time, creating and deleting B2C users over multiple Azure tenants, by 30-40%. Deployed on Azure Kubernetes.
- Developed an interactive 3D Airport Map application using Visioglobe, installed at Miami Airport. The application provided an interactive help service for passengers to find Points of Interest (POI) Originally developed in AngularJs but upgraded to Angular 10+. NgRx was used for State Management. The web client runs in an Electron application. RESTful web services were developed using Grails and Spring Boot. Integration and unit tests were written in Spock using Groovy. Web services and supported web apps were deployed on AWS.
- Developed a performance tool, using Locust and Python, testing application load management using RESTful APIs. The tool ran within an Azure Pipeline, in a docker container. A PDF report is generated, using Matplotlib graphs, producing data analysis of the average response and hit times for each web API. Unit tests were developed using the PyUnit Framework. Results of the performance tests highlighted bottlenecks in a series of web REST API calls that were resolved before going into production. The performance testing allowed production updates to be made without causing operation down-times at airports .
- Managed a development team of 5+ developers, to support an Airport Management System (AMS). AMS allows airlines to schedule flights and allocate airport resources, such as check-in gates, departure gates, and runway usage. My onsite support, in South Africa, ensured that the system was able to handle the million extra airport passengers for the 2010 FIFA South Africa World Cup. Written in C++, COM and STL, using MS SQL Server
