I love working on new challenging projects and surprising my clients with unique & creative solutions. Always thinking outside the box and my experience in research, development, and solutions reflect this. Proudly a top-rated freelancer on Upwork (100% Success) for this reason.
As a professional in telecommunications, I am very good at communicating with people about technical solutions because my day-to-day job previously was Cloud-Based Contract Sales for Telstra, which is the biggest telecom company in Australia; Technical Solutions and B2B sales in Data, Voice & Fiber.
I'm a Linux expert and can write amazing code, applications, and scripts, in many different languages. My favourite languages are C, C++, Python and shell (BASH/POSIX). I am also very good at PHP, JavaScript and other interpretted languages. I am a master of Docker. Can create all types of interfaces, ncurses, GUI's, GTK, QT.
I can create SAAS-grade internal-use scrapers & browser automation: cURL, Selenium (chromedriver/geckodriver), auto-scaling, auto-deploy. I've written the backend for various high-traffic and high-value services.
Great at solving problems - being able to see solutions that are outside the box and use creative techniques to manipulate data or market analysis through big-data scraping.
Hope to work with you and your business.
