-Data Modelling and Database Design Create database designs by performing needs / requirement analysis, creating a logical mode, and then implementing the physical model. -Backup and Recovery Making periodic backups of data and keeping it safe from accidental or intentional destruction. Testing recovery plans so that when problems do arise, data can be restored quickly. -Capacity Planning Watch data growth, and plan how best to deal with it. This may include archiving it, increasing the size of current hardware, or adding new hardware. -Change Management Server configurations, database schema change over time. Perform impact analysis before changes are made, implement changes, test changes, and document them. -High Availability Ensure high availability, including use of log shipping, clustering, database mirroring, and other technologies. -Monitoring Monitoring performance, monitoring server disk space, monitoring logs, ensuring jobs have run successfully, checking for errors, and so on. -Needs/Requirements Analysis Perform needs/requirements analysis. Talking to users, finding out their needs and requirements, and determining the best way to meet them. -Performance Tuning Monitor performance to determine ways to optimize database performance. -Report Writing Writing reports against databases in transact-SQL code to extract the data, or creation and formatting physical reports. -Security Control who can access data and what they can do with it. Creating SQL Server login IDs, database IDs, assigning permissions, moving security between servers. -Testing Testing servers, testing databases, testing applications, testing management tools, and so on. Ensure that data integrity and high availability, is maintained at all times. -Training Users Sharing knowledge with other DBAs, developers, or end-users. -Working with colleagues Interacting with other DBAs, developers, end users, product-knowledge specialists, vendors, accountants, hardware experts, and networking experts.

My tech stack: Python, Node.js, Bootstrap, iOS, MongoDB, PostgreSQL, Hadoop, Linux, etc. Since 2011, I have been running a service to collect user behaviors and do data mining for several eCommerce websites in China mainland. The service could be deployed as SaaS or in house. Tech Stack: Python, Django, Node.js, MongoDB, Hadoop, etc. http://tuijianbao.net Before that I participated in development of frontend and backend of e-commerce website http://www.nordicbet.com as a developer. Tech Stack: Python, jQuery, etc. After graduated from college, I joined GE Healthcare China as a developer. Built HIS/RIS software for hospitals in order to help patients indirectly. http://www.ge.com I would like to participate in Python/Node.js/MongoDB/iOS projects and always do my best to push your business forward. Cheers, Liwen
I have 14 years of experience in software development and believe there is a direct connection between design and the ease of use and efficacy of software. If the fundamental design is good then enhancements are very often natural extensions of it. I view testing as integral to development since the programmer will always have singular insight in understanding how to test his or her own software. I like to exceed expectations and I know from experience that doing so requires the ability to anticipate as well as solve problems.

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
