Giancarlo Mendoza

I’m a Data Analyst with 2+ years of experience in fintech, specializing in data analysis, automation, and business-focused data visualization. I use SQL, Python, and Power BI to structure metrics, optimize processes, and support data-driven decision-making.

At Leasy, I designed and deployed a strategic collection portfolio dashboard integrating PostgreSQL and BigQuery, reducing delinquency rates from 80% to 17% within 12 months. I also automated the processing of 10,000+ monthly billing records, eliminating manual Excel reporting and enabling structured historical tracking.

I’ve built reliable data pipelines by integrating PostgreSQL, BigQuery, and external APIs, and I’ve implemented operational alert systems using Google Sheets plus GPS API data. This reduced average blocked asset recovery time by 75% (from 88 to 22 days) and escalated critical events via Power Automate to prevent an estimated losses of USD 2M from inactive assets.

Before this, I worked as a Learning and Development Trainee with experience in HR and People Analytics, including KPI-driven reporting and executive-ready talent dataset validation. I’m now seeking a remote Junior Data Analyst role where structured analysis delivers measurable financial and operational impact.
