    My name is Branden, and I've been programming since the age of ~13. Soon after I started, I grew fond of automation - I realized that I had so much fun watching something automatically happen on my screen. But even more than that, I got the most fun when it was something I made. Whether it be a simple pixel bot clicking around a game, or a complex scraper outputting a stream of data for me to view, it's always given me the same feeling of joy, and I strive to get that feeling every day. I've worked with many, many clients on a wide range of projects, and done hundreds of personal projects for myself. Every automation project is a unique challenge that I find thrilling. I love speed-coding, and in fact I often complete an entire scraper and sample set before even bidding on a project, confident that it is 10 minutes for me but 1 week for other Freelancers. Let's discuss your needs - web scraping, data mining, scrapers, bots, pixel tools, messaging tools. I can do it all. less
