    Nate West

    Software Engineer

    United States - Last active: 4 months ago - Tests: 1

    I’m a web developer in the Nashville Metro area. I have great passion for education and learning and am always looking for someone to learn from and someone to teach. I work full-time in town but do have time for part time contract work (around 10 hours a week). I've worked in small startups on large international corporations. I have extensive experience architecting and building authorization systems with OAuth 2 and OpenID Connect. I love working with distributing systems and SOA. My Philosophy: I adopted the hacker attitude as my philosophy at an early age. This is how I view the world. 1. The world is full of fascinating problems waiting to be solved and I want to solve them. 2. No problem should ever have to be solved twice. Knowledge should be shared and things that cost money, time, or morale should be automated. 3. Boredom and drudgery are evil. If you’re bored, you’re doin’ it wrong. If you’re doing busy work that could be automated, you’re way doin’ it wrong. 4. Freedom is good. Let me clarify: freedom is good. 5. Attitude is no substitute for competence. Developing competence takes practice and hard work. I like to practice and I respect others who feel the same way. My Numbers: If you like charts and graphs you might want to take a look at some of these links. https://coderbits.com/drumsrgr8forn8 - Coderbits aggregates data from a ton of web site (Github, Code School, Bitbucket, Linkedin, etc) to create charts that give you an idea of who I am as a developer. http://osrc.dfm.io/drumsrgr8forn8 - Open source report card analyzes data from Github to give you an idea of what my coding habits are.

    Software Engineer

    New Zealand - Last active: 3 months ago - Tests: 1

    I am a professional Software Engineer with experience in Python, C++, Java, SQL, NoSQL and a wide variety of other technologies. I have experience in managing and maintaining cloud applications in a high availability environment. Most recently I have worked as a Server/DevOps Engineer, creating and maintaining server-side software for several smartphone games with over 100,000 users. My responsibility was for the whole development process - from specification to release, through to live updates, data management and performance analysis. I worked on creating server-side functionality to support new features in the smartphone client with a focus on high throughput and database performance. As part of my DevOps responsibilities I maintained 60+ AWS EC2 instances running high availability server software, PostgreSQL and Redis. I also designed a new server architecture for a new game with a focus on scalability, throughput and maintainability. I am a task oriented and enjoy the process of working through a project from design to completion. I enjoy working in a collaborative environment and sharing ideas and experience with colleagues. My goal as an engineer is to create high quality, high performance software with an awareness of business and customer requirements. I have a Masters degree from the University of Warwick, UK. My degree had a focus on algorithm design, data design, high performance computing and system design. I am currently studying statistical analysis and stochastic processes to further my understanding of data science and simulation. I have an interest in high performance software, distributed systems and modelling/simulation software. In particular I am interested in the application of using simulation software and modelling to solve real world problems.

    Senior polyglot web and mobile developer

    United States - Last active: 06/13/2014

    I'm a senior developer of web and mobile applications, with expertise in a variety of languages and technologies, some of those being very trending and new in the development community in general. I can reach out to all parts of a particular project since my experience includes all components from the bottom (database and C code) to the top (JavaScript, HTML, CSS), most of them being the best. Have a great understanding of object oriented programming, driving it through Data Context Interaction, also a Behavior Driven Developer (BDD), agile practitioner, system administration, full stack software development, API design along REST and hypermedia, most importantly a fast learner.
