Edmentum products enhancement and new features implementation.

Big Time is customizable time & billing software for professional services firms, designed for easy adaptation and smooth integration with each firm’s existing procedures for engagement workflow, billing and tasking. Designed to work seamlessly with Intuit’s QuickBooks, the accounting version uses a familiar timesheet format and specialized billing formats for accounting that include multiple billing rates, write-up and write-down (for WIP analysis), and progress payments.

The timesheet formats enable staff to enter their daily time at the end of each day or use a timer, with simple reference to client lists and billing/expense codes. Big Time offers a flexible rate structure tailored to each client, with the ability to invoice standard time and expenses, or fixed-fee engagements - with numerous printed invoice styles and limitless billing formats.

Big Time is designed to “learn” from the workflow style of the accounting firm. Each client plan is saved in the system as a “virtual template” from which engagements, special projects, rates, tasks and team members can be copied for new clients. Management reports can enable automatic analyses of WIP (by staffer, billing code, and client), capacity and other critical measures, and offer more than 150 standard report templates and endless report customization options.

USA comedians and comedy clubs network. Service helps involved people to introduce themselves to the audience and clubs to advertise their events.

Comedians are imported from Symfonee by self-written service (implementation based on Kooboo CMS tasks). Also comedians can be created in the administration part of the website (preferably based on Kooboo CMS). Every comedian has its own customizable page where he can manage his photo, about text, upload and manage videos, show up his fans, list upcoming shows where he performs with ability to buy tickets, show RSS feeds, view custom HTML content, view banners and twitter feeds. Moreover, every content block is easily manageable (works on one page) and draggable. Comedians can add, delete, drag and drop content blocks and review the layout. Everything can be reverted to the default state.

Simple users can register themselves using external services such as Facebook, Twitter, Yahoo, Windows Live, Google, LinkedIn, Blogger, Worpress, etc. (provided by Gigya). As well they can become a fan of comedian, comment videos, take a part in different contests, share content with friends using Facebook or Twitter, buy tickets to the shows. Also every user is geo-targeted, service tries to determine users location by IP and sets up the home page: shows by default a nearby club and events.

Blog allows administrator to write blog posts with any desired content, also supports tags, archive, RSS feed, sharing and comments.

Calendar page displays upcoming featured events as well as all events list, where user can see upcoming events and buy tickets. There is also a calendar-like club-specific view of this page, where users can see events split by days and months.

Every club has presentation of its own dining menu, groups and parties rules and allows users to purchase a gift cards.

Essential part of the project is video encoding service (separate IIS application) that in a collaboration with major site allows comedians to upload and show videos. When user hits the upload functionality, system loads raw video file to the Amazon S3 bucket(using swfupload), then downloads it to the local server, encodes with ffmpeg with desired settings, extracts thumbnails and uploads everything back to the Amazon, then system receives and saves urls which can be passed to the browser and video players.

Moreover, a lot supporting pages and sites are implemented:

• dearcomic.com – admins can queue up comedians, which are promoted to answer users questions. Comedians are notified with asked questions.

Implementation is based on a set of Kooboo CMS modules (had been updated manually to support custom written modules), which consists of ASP.NET MVC Controllers and Views. Each module uses internal Kooboo data processing functionality, as well as LINQ to SQL to call MS SQL Server stored procedures that create, update and delete more complex data sets. Also database views and triggers are created to preprocess and combine data.

Fontend site uses ASP.NET MVC 2.0 Views to render data, with heavy usage of jQuery, jQuery UI and open source jQuery plugins (sliders, scrollers, corners, labels, timers, tooltips, validation, timepickers, cookies, rich text editors, etc.). Styling is based on plain CSS + SASS + Compass tool.

Blacklots is an art auction platform for the resale and acquisition of contemporary art. Allows buyers to push their things on sell using auction system.

Then XML can be uploaded by the website and updates data in database. After the update website automatically synchronizes music data with Last.fm service using its API, loads performers photos, tags and a list of similar artists. Resulting information about music can be viewed in cloud or alphabet manner

Credit Risks Online is a back-office connectivity solution created by the Renaissance Capital Dedicated Development Center. Application allows stock traders to calculate risks relative to the trading positions and stock market state on a real time basis (5-10 min latency).

Database site is based on Informix database with heavy usage of stored procedures, functions, views, triggers and indexes. First approach processing compiles data into corresponding views (~40-50 columns), then COM+ layer transfers data into the data processing layer of application that manages tricky formula calculations and stores data into the heavy local memory cache and MS SQL Database. As well data processing layer exposes .NET Remoting service to deliver data to the client applications.

Client applications are implemented using WinForms with heavy usage of Syncfusion solutions to represent the data.

Positions Manager Prototype is a distributed finance risks calculation application prototype. The major point of prototype creation was to research the availability to calculate finance risks based on trading positions by the distributed horizontally scalable system.

The major implementation was based on TIBCO Rendezvous and TIBCO EMS products which allowed to split the calculations among worker applications and adjust the cross-workers communication. Worker represents C# application that uses TIBCO Rendezvous to listen the data required to process, receives it if any, manages all calculations and sends data forward or stores it locally.

The results of prototype's implementation were a set of load tests and team reviews to decide how to integrate the system into further projects.
