    Currently a Security IT consultant specializing with Splunk, I possess a wide variety of skills and have worn a number of hats. Previously, the best summarization of my skillset is a hybrid between software engineer and sysadmin in what is now considered a devops engineer. My focus then was mainly automation/scripting and monitoring in an infrastructure engineering role. With this speciality, I'm particularly looking for remote, part-time work at this time, focusing on Splunk. Other side interests include mobile/web app development with native iOS. I'm very adept with the full Splunk stack in terms of architectural design to building custom parsers to dashboards. In particular, I probably enjoy the parsing for search fields the most? Report generation and scheduling alerts is no big deal to me so long as the customer has clearly defined requirements for high value reports within confines of Splunk. I have been offered and worked contract jobs for Splunk positions as well as know the going rate for professional services for Splunk, so I know my going rate is more than fair. What you get from me: * Excellent communication skills. I've worked with Agile before, so I have a better understanding of building quantifiable user stories as well as prioritizing value and time in communicating this. * Deep understanding of Splunk. Probably the most obvious out of this profile you can read. * Solid project management skills. I personally ran a 1-man project for an organization, so I'm familiar with bringing up an entire environment with limited resources for you. * Entrepreneurial thirst to learn. I enjoy learning new technologies and languages. Very avid in the startup community. I am also dabbling with mobile and web app development, learning a combination of JS and Ruby among others. If you'd like to know more, feel free to contact me! Rate is negotiable, feel free to discuss as part of project ramifications.  less

    My primary area of expertise is back-end implementation of web applications and websites using Java and SQL. Many a time, I have worked on projects that had fairly high algorithmic complexity (like pattern detection engines) and required creativity to design innovative solutions for problems. I have also worked with web services and done a little bit of front-end coding with HTML, CSS and Javascript. I am familiar with Ruby on Rails. I would like to be part of a team for large enterprise-projects. I can also create websites for small businesses and entities as a single contributor or part of very small team.  less
