My self-driven and self-taught approach to studying computer science is what made this dream possible. Web Scraping & Web Automation. In addition to full stack development, I have extensive experience in web scraping and web automation with Selenium. I’ve built dozens of high-performance tools for tasks like product monitoring, data extraction, and browser automation. One of my standout projects was a Windows application built in C#, Winforms, and Bunifu that launched parallel headless Chrome browsers to automate checkouts on Supreme New York, enabling users to secure limited-edition drops with speed and precision. My automation work spans a wide range of use cases, including crawling Amazon product listings, finding vehicles to flip on Craigslist, gathering market data on boats and funeral homes, as well as tracking competitor pricing in real time. Whether it’s navigating complex DOM structures, avoiding detection mechanisms, or designing tools for non-technical end users, my ability to automate the web efficiently and reliably is unmatched. Let’s build something great together! I am just getting warmed up so take advantage. Cheers, Dylan
