Developer with 4+ years of experience working with a multitude of modern programming languages. With my wide breadth of knowledge, you can rest easy knowing the right technologies are in use for your project. Finding a team to properly write software can be very difficult — I know this first hand. A custom piece of software needs to be developed in a robust, clean, and expandable way. Unfortunately, these details are often an afterthought, and unnecessary time and money is spent to rewrite code when the demand or requirements change. By using extensive study in the field of software design principals and methods I can greatly minimize these risks; saving you money when things change (and let’s face it, they always do). With me you not only get someone who knows the language — you get someone who understands the big picture and how it all fits together in a way that allows your software to grow with your business. Common projects I undertake include: - ETL Pipelines - Full Stack Web Development --- Django --- Flask --- CppRest --- jQuery --- Postgresql --- Mysql --- Memcached --- Redis - Dockerizing - Multi Platform Projects (Windows, MacOS, Ubuntu) --- GUI Applications --- CLI Applications --- Tools and Libraries - Specialized Domain Heavy Applications - Embedded Development --- ESP8266 - Web Automation - Many moreCryptography
