Work Experience

Experience
External Webhook Security Audit Service
https://github.com/firegrass/WebhookProxyFreightliner Group | Train Driver Application Service
https://www.freightliner.co.uk/I was retained to build a web service to meet the demand and improve the data collection. As the organization did not have technical people, I worked with my point of contact to define detailed requirements and ensure their needs would be completely met.
They were short on time and a new solution needed to be ready in 2-3 weeks. I built, tested, and deployed a service within the time allowed and monitored the stack while the job advert was live.
The solution successfully processed over 8,000 applications in a week and was even used three more times over several years.
