Experience
Intelligent Robotic Process Automation Platform
https://www.youtube.com/watch?v=GsTofPeguTQThe development commenced in early 2017, I joined the company as number three, and assumed the head of engineering role. I had the pleasure of hiring and working closely with a new product team comprising two front-end developers, an API developer, a QA engineer, two data engineers, a DevOps engineer, and a product manager.
I was hands-on across the stack, from infrastructure to operations to APIs, while also working closely with front-end development and product management to ensure that high-quality product features were developed and shipped in a stable manner to production. I also provided technical leadership and mentorship across the entire product team.
The system was 100% cloud-based and multi-tenanted, utilizing 100% IaC to support the same stack across three regions in Sydney, Dublin, and the United States.
