What I'm looking for

I’m looking for a Junior Data Analyst role where I can build ETL/ELT pipelines, clean and validate data, and deliver dashboards using Python, SQL, and BI tools—while collaborating with stakeholders to improve operational decision-making.

I’m a Junior Data Analyst with a mechatronics engineering background, combining analytics and systems integration to make data usable. I use Python, SQL, Pandas, and Tableau/Power BI to clean data, perform EDA, and deliver KPIs that support business reporting.

Most recently, I supported Odoo ERP implementations—gathering requirements, mapping processes, running UAT, and translating needs into functional specifications for traceability. As a freelancer, I automated access to operational data by integrating MongoDB, Odoo, Google Sheets API, and n8n with webhooks and Python scripts, improving how non-technical users retrieve information. I also built ETL/ELT workflows and dashboards, including a TripleTen YouTube Trends Dashboard with regional insights.

Across training and projects, I’ve worked end-to-end: data validation, transformation, hypothesis testing, and clear data storytelling. I’ve also developed scikit-learn models for regression, classification, and clustering using cross-validation and ROC-AUC—while earlier experiences in computer vision and engineering automation shaped my focus on reliability and measurable impact.
