Static Website for a Law Office

https://www.hla-law.com
Flask-based static website for informational purposes. With a basic admin panel to add/edit/remove articles and news. Integrated Google Maps and QR-code contact download from the shortened URLs. Interesting feature: a few pages are directly rendered from the .docx documents using "Aspose.Words". Bulma CSS is used for styling. Hosted on pythonanywhere.com with HTTPS redirection from the domain provider.

Live Preview Questionnaire

This project allowed healthcare staff to create questionnaires to be assigned to patients. That way, we gathered patient information and structured the data meaningfully using a many-to-many relationship between the patient table and the questionnaires table. A live preview was also possible during creating the questionnaire in case the creator wanted to see how a questionnaire would look from the patient's point of view.
