Hello client, my name is Salman ullah and I am a freelance developer with expertise in Data Science, Python, machine learning, and Django. I understand you are seeking a developer or team to enhance your system. Specifically, you require someone who is familiar with three primary technologies used in your comparison website system - Pipeline developed in Python, the database developed in PostgreSQL, and scraping bots developed in NodeJS.
I believe that I am the perfect fit for this project due to my extensive experience in data science, programming languages such as Python and Django, along with other related technologies such as web scraping. This combination gives me unique skillsets that will be invaluable when it comes to enhancing your website system.
With my skillset at hand, I am confident that I can deliver high quality solutions for your project requirements. Plus, because of my commitment to communication, collaboration and transparency I am well suited for this project - both during the development phase as well as after its completion.
