Hassaan did an excellent job! He built a clean and efficient web scraping script that extracted exactly the data I needed. The code was well-documented, easy to run, and delivered right on time. Communication was smooth, and he even provided a short guide on how to reuse the script. Highly recommended for any automation or scraping tasks
