    I have 10 years of experience in different areas of software development. My most recent experience lies in field of backend development of horizontally scalable solutions for data processing. During last 2 years I have been developing from scratch proprietary framework similar to Apache Hadoop and Spotify Luigi for batch data processing (billions of log records of ad data daily). I used Python as core language to promptly prototype data analytics business logic with a goal to rewrite it in native language without API changes later. This project also involved managing NoSQL databases (TokuMX or MongoDB 3+ with an appropriate storage engine) to process, aggregate and store massive (hundreds of millions daily) number of documents, indexed for further statistical analysis and reports generation. I also have experience in the following areas: - development of web backends in Python using uWSGI and Tornado frameworks - automation of code building and deployment, Vagrant, Docker - C# language and some experience in Java and C/C++ I am an open-minded technology enthusiast with strong algorithmic and mathematical background and keen attention to details. New language, technology or framework required for next project is not a problem to learn at all. I am ready to show positive, constructive and helpful attitude to your tasks.  less

    About me in two words: software craftsman. I am always looking for new technologies and new solutions for a known problems. In fact I’ve first started use NoSql databases four years ago. I’ve started from ravendb, than become a huge fun of mongodb. I’ve tried redis, memchaed and read about cassandra and riak. Almost in same time me, and my collegues build our first CQRS based system. Year later we’ve started use CQRS combined with Event Sourcing and continue use it today. I don’t believe in golded grail. Everything changes and I enjoy keeping up to date with new technologies. Technology Radar by Thought Works helps in that a bit. Behind my main proficiency(.net) during last two years I’ve tried and learned node.js and Dropwizard java framework built by Coda Hale from Yammer. I also greatly improved my client side skills and built two single page applications. One is based on backbone (Theranest) and another one is based on angular (Hummingbird). I have one rule when starting new project: “Try something new”. I’ve strongly believe in the open source. Me and few other Paralect founders build open source tool for mongodb management robomongo (http://robomongo.org/). It is widely used around the globe and has between 500 and 3000 download per day. I am StackOverflow'er (http://stackoverflow.com/users/508601/andrew-orsich). I am very proactive and enjoy impact to the future of the project I am working on. I am always analyze a market and trying to come up with better, or improved ideas. My previous customers liked that about me a lot. This passion combined with my intention to learn and apply new technologies helped me to create and run two startups: Theranest and Hummingbird (see more details below) over the last year. Theranest now successful startup which is constrantly growing. Hummingbird just opened for a beta clients. Performance, scalability and big data was most interesting to me over the whole my career. During this year I want to apply my teoretical knowledge of Twitter architecture (batch, serving, real time layers) and make deeper step into Big Data world. I want to try Twitter Storm and Hadoop on a real project. I am comfortable being uncomfortable. Current technology stack is: Server side: ASP.NET MVC 3-4, C#, Signalr, MongoDB, SQL Server, Lucene for full text search, Quartz.net for scheduled tasks, Dependency Injection, NLog. Node.js, express, socket.io, mongodb, etc. Testing: Unit Testing, UI testing with Selenium Client side: BackboneJS / KnockoutJS / AngularJS, RequireJS, Twitter-Bootstrap, jQuery, Mustache, Underscore, etc. Certified mongodb DBA - https://s3.amazonaws.com/edu-cert.10gen.com/downloads/0a986eb852da42d0967db95e132bc44a/Certificate.pdf  less
