I am very good in preparing documents including Project Proposal, Scope, User Scenarios, Features, Functional Requirements, Data Modeling, Workflows, UML, Wire-frames, Tasks Sheet, Work Order and Milestones - I am expert in writing intelligent and complex algorithms. I have developed Stacking, Packing & Picking Plans Generation and Forecasting algorithms - I have worked in conventional and AGILE Scrum environment - I have developed mobile web applications using HTML5 and JQuery Mobile - I have good architectural, organization & communication skills - I am self-motivated, creative, honest and hardworking - I am not a traditional or typical developer; I always think out of the box and love the challenges I have worked on many applications including Material Resource Planning, Distributed Resource Planning, Electronic Inventory Management, Barcode, Logistics, Transportation, Shipping, Supply Chain, Forecasting, Warehouse Management, EDI, CRM, CMS, FMCG, Manufacturing, Costing, Trading, E-Commerce, POS, Accounting, Finance, HR, Payroll, Institute/School Management, Email Marketing, Social Media, Rewards & Loyalty Program, Health Care, Hotels Booking and Microsoft Active Directory, Exchange Server and Office365 solutions. Among my strongest areas are architect designing and design patterns implementation such as MVC, Singleton, Factory Method and Dependency Injection. A good architecture provides a strong base to application. I divide whole project in independent and fully functional tiers and layers such as GUI, Business Logic and Repository (DAL & Database), any change in any layer does not affect others, for example change in Business Logic or database will not affect GUI and likewise. To take full advantages of a good architecture I build my own DTO (Data Transfer Objects), BO (Business Objects) and Foundation. This architecture enables me to make any change, bugs fixing, enhancement, parallel development and TDD/ Test Automation quick, simple, easy and effective. I prefer to use Provider Model (Interfaces/Factory Method/Extensibility) if application is extendable and dynamic in nature. My objectives are very clear: client satisfaction at best level, excellent feedback, learning, earning and a good everlasting business relationship.

    MongoDB/CQRS/ES/ASP.NET MVC/Node.JS/AngularJS/BackboneJS

    Belarus - Last active: 4 months ago - Tests: 3 - Portfolio: 5

    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
