In my second phase in the company, I had to maintain old cloud workloads hosted in AWS and continue developing new features to automate several kind of tasks. Among those features, we should remark the following:

Data & Cloud Engineer

During my first 6 months, I was assigned two major features:
a) Cloud-based daily performance report: consisting on automating several long, hand-made tasks. I was given a GCP project and started learning about the required services such as Cloud Storage or Bigquery.
This automation led to an important labor hours and costs reduction (more than 30k€/year)
b) Internal optimization app: web full-stack development hosted in GCP Compute Engine. I had to build the front-end (coded in Vue.js) and take control of the back-end (python + MongoDB) once the external consultant who coded it left
