Situation
I started working at a quick-commerce company a year ago, after leaving the first Indonesian unicorn company in December 2024. The company is a subsidiary of my previous employer, and I joined through an internal transfer.
At first, our data platform was managed by the holding company, and I supported it while on call. Later, the holding company stopped providing support. Because of this, my company asked me to build a new data platform from scratch in a separate Google Cloud Platform (GCP) environment.
Task
The first mandate was clear. The data manager asked me to create a data platform that could seamlessly integrate with the existing reporting platform. At that time, there were only two data analysts, and they were already busy supporting data stakeholders across the company.
Action
I built the data platform using a Lambda Architecture. I ensured that the outputs in our new environment matched the data warehouse tables used by existing reports in the holding company’s environment. This allowed us to migrate smoothly without disrupting reports.
Result
I successfully built the data platform in our environment, and completed the migration smoothly with a single click by switching the Looker data sources from the holding company’s GCP project to our own. The entire migration took less than 30 minutes, and there were no issues with existing reports.
