You will get Custom Web Apps with Python – Flask, Django, FastAPI Backend Development
Project details
I have developed a webapp for pricing analysis using Django (backend) and React.js (frontend, if needed for advanced interactivity). The platform allows users to upload data (CSV), perform price elasticity analysis using SciPy, and visualize results through interactive charts with Plotly. Users can also download detailed PDF reports generated using ReportLab or WeasyPrint.
Key Features:
User Authentication: Login and sign-up functionalities built with Django.
Data Upload & Validation: CSV data upload with error handling and validation using Pandas.
Price Elasticity Analysis: Python-powered analysis using SciPy.
Reports: Interactive charts and downloadable PDF reports.
File Storage: Integration with AWS S3 or Django file storage for scalability.
Technologies Used:
Backend: Django, Celery (for background tasks)
Frontend: Django templating, React.js (for dynamic features)
Data Analysis: Pandas, SciPy, Plotly
Report Generation: ReportLab/WeasyPrint
File Storage: AWS S3 or Django File Storage
