I developed data pipelines for a renowned fashion retail company, effectively delivering crucial insights on sales, products, inventory, and customer data. Utilizing the Python programming language, I employed a container-based approach within Google Kubernetes Engine (GKE) to optimize data processing. For securely storing raw data, I relied on Google Cloud Storage (GCS), and for managing processed data, I utilized Google BigQuery, making it accessible to various teams for enhanced decision-making.

In this role, I teamed up with a former colleague to explore the financial market through data analysis and algorithm development. Our aim was modest yet clear: to build algorithms capable of generating steady profits. We managed to run our venture in a way that covered operational costs and provided us with basic salaries. Despite the challenges and risks involved, we gained invaluable insights into managing a business at this early stage of our careers. Eventually, recognizing the scalability limits of our project, we decided to close the venture. This journey was a crucial learning experience, enhancing my skills in risk assessment and the realities of entrepreneurship.
