What I'm looking for

I'm looking for a Data Scientist, Data Analyst, or Full-Stack role.

At Sahel Auto, I designed and developed an after-sales service management platform with React.js, Flask, MySQL, and REST APIs. I integrated machine-learning models for sales forecasting, appointment prediction, customer segmentation, and anomaly detection.

I prepared and evaluated data for those models, and deployed them through the Flask backend for real-time predictions and recommendations. I also developed an NLP-powered chatbot to automate customer assistance and service requests.

For the platform, I created interactive Power BI dashboards and KPI monitoring tools for operational analysis. I collaborated using Git/GitHub and Agile (Scrum) practices.

At SW Consulting, I analyzed and cleaned business datasets using Python and Excel, then built dashboards in Power BI and Tableau. My academic projects include a React.js, Spring Boot, and MySQL beauty routine tracking app, and an Amazon sales analysis using Python, Pandas, NumPy, and Power BI.
