From your project description, it is evident you need more than just a web scraping expert to tackle the depth of your project. That's why as a team of full-stack developers, including software architects and an extensive list of coding languages under my belt, we can efficiently perform all the necessary task for this job in the most effective manner.
Our experience in web development and deep knowledge of many frameworks, including MERN, MEAN, MEVN, MENN and even E-commerce solutions like WooCommerce would set us apart in tailoring the ideal scraping strategy for each specific e-commerce site and meetup.com. Our skill set also includes proficiency in database management, where we can organize and clean collected data not just in CSV format but also paired with SQLLite, Postgresql or MariaDB based on your preference.
Lastly, but probably most importantly, is our adherence to ethical considerations when handling data from the web - we understand and respect privacy laws. Rest assured that data collection will be done within legal bounds.
