Summary
I am currently working full-time as an Application Administrator at Tambla on the infrastructure team and work closely with development and QA to ensure that Tambla SaaS applications and infrastructure are running smoothly and deployed correctly.
Outside of work, I am pursuing a Diploma of Information Technology (Advanced Programming) part-time and have spent the last eighteen months learning how to code in C#, JavaScript, and T-SQL in order to create websites and applications.
I have a strong understanding of the principles and practices of Infrastructure and software development, as well as excellent communication and problem-solving skills.
