As an experienced professional who has developed and managed databases for over 18 years, with a focus on MySQL and SQL Server, I believe I am the ideal candidate for your recipe scraping project. I have in-depth knowledge of Python and its associated libraries, including expertise in software architecture, enabling me to operate effectively within your desired framework of Python 3.12 and PYQT6. Furthermore, having extensively worked with databases and reporting tools like Power BI and SSRS, I am well versed in SQL Server Programming and thus capable of utilizing the SQLite3 database format you've outlined.
The task of scraping receipts from multiple websites simultaneously is inherently challenging due to the issue of Captcha/IP blocking as a result of excessive requests. However, my intricate understanding of request processing and data extraction methods combined with a strong grasp of anti-crawling measures will be highly valuable in ensuring uninterrupted data retrieval from the target sources.
Moreover, my experience with large-scale IT enterprises across diverse domains such as healthcare, banking, manufacturing, retail, etc., equips me with an innate appreciation for domain-specific requirements.
