> Principal Software Developer @ Splunk
On this web site I publish my personal thoughts and ideas. I am not speaking for any company in my blog posts.
From 2005 participated in various projects, including solutions for analytic, enterprise applications, CAD-software, tools for developers, mobile applications and big-data solutions. Contributed in several open source projects. Have experience in building distributed systems, back-end, front-end and mobile applications. Know how to build scalable systems and design any kind of applications from the ground. I have system programming experience in Windows, Linux, OS X and Solaris. I am a geek, like to build software, like to learn, like to solve hard and interesting problems. Share my experience on meetups, blogs posts and conference talks. I am experienced individual contributor with strong Technical Lead skills.
I’m happy to answer on your questions and discuss interesting topics
