05/07 – 05/09
Communispace Corporation www.communispace.com
Watertown, MA
Senior software engineer
Company specializes in building and managing online
communities for marketing research purpouses. Company uses
SaaS business model.
Architected and prototyped next generation of the company’s
core application.
The architecture is multilayered and consists of:
 Database (SQL Server 2008)
 Data Access Layer (Microsoft Entity Framework)
 Service Layer (configurable through CSLA data portal or a
custom Web service API)


Business Layer (CSLA 3.6)
UI layer (CslaDataProvider, but any UI pattern can be easily
“plugged-in”, including MVC/MVP/MVVM and Microsoft
MVC.Net)
The architecture has been taken as base for building company’s
new generation core application.
Database model is composed of multiple logical sub models
including business entities, personalization and security ones. The
model is designed in a forward compatibility fashion, for example
to be able to easily add new business entities. New SQL Server
2008 data types and features are used. For example,
datetimeoffset - to support localization.
Data Access Layer implemented as entity model, auto generated
from the database. LINQ to Entities is widely used to query data.
Each business class has it’s own object factory to implement
CRUD functionality.
Service Layer is currently exposes standard CSLA data portal
CRUD signatures. Configured either as a local portal or as a
remote WCF service.
Business Layer is implemented as a class hierarchy inherited from
CSLA base business objects. Base business classes define
standard validation and business rules/behaviors. Due to existing
company’s business requirements a custom authorization
subsystem has been designed and implemented as collaborative
addition to CSLA framework. All business classes support two
platforms - .Net and SilverLight (both synchronous and
asynchronous clients). All classes support configurable loading on
demand or “lazy loading” to control performance.
Developed and tested a complete “vertical slice” to demonstrate
specific business activity in action. UI implemented as
asynchronous RIA client (SilverLight). Custom authorization
system has been successfully tested.
Created a specialized multithreaded deadlock tracing tool in form
of .Net Windows Forms App. The tool simulates simultaneous,
“racing” connections to reproduce and isolate deadlocks. As a
result, data modification code has been re-written in a deadlock
free fashion. The tool can be customized to practically hunt
deadlocks in any SQL Server database. There is also a variation of
the tool targeting Web services.
Tuned up database queries and replaced some of the existing SQL
scripts to improve overall database performance. Used numerous
features new to SQL Server 2005, for example CTE (common table
expression). Modified existing database schema to improve
performance and data consistency. Re-designed existing data
import SSIS packages which has reduced execution time by about
20 times. Designed numerous data exchange scripts optimized for
speed and size.
Architected and implemented completely configurable integration
solution to bring up one of the MarketSight’s web based data
analysis
tools
(http://marketsight.com/assets/demo_1/marketsight.html) into
an existing classic ASP web app to upload and remotely analyze
data, collected by web based surveys. Extensively employed XML
data formats, SQLXML, Web Services, ASP.Net, SQL. The heart of
integration is a set of SQLCLR stored procedures and a custom
business class hierarchy in C#.
Architected and implemented one the most complex parts of the
company’s application – the Survey Builder module. The new,
multi tier web application business logic implemented as a library
of
CSLA.Net
derived
busyness
objects
(http://www.lhotka.net/cslanet/).
C#, ASP.Net, Web Parts,
MasterPages, Personalization, Theaming, AJAX, loading on
demand (LOD), caching techniques.
Developed “QA tests” application as a multithreaded Windows
Forms MDI application. New types of tests can be easily added
with a minimum coding effort. Tests can be created, persisted to,
restored from configuration XML files and run simultaneously via
Windows Forms based GUI. .Net Windows Forms,

Eliza Corporation, www.elizacorp.com , Beverly, MA
Software engineer
Responsible for enterprise level data processing and automation
tasks, development of enterprise level data management client
tools and administering of all SQL Servers.
Designed enterprise level Windows and web applications.
Based on internal company requirements, designed and
developed the information system to keep and manage allocated
phone numbers and TELCO related information. Speech
application developers can request new phone numbers for their
applications through the front-end web interface. Administrative
back-end tool allows processing requests and automated
dispatching of phone allocation requests to the telephone
company.
Instruments: C#, SQL Server 2000, Windows Forms, ASP.Net,
ADO.Net, XML WebServices.
Development of the next generation real time data exchange
system which fits in the tier between the existing production
databases and real time speech applications.
Instruments: C#, IIS, ASP.Net, Remoting, HTTP, WebServices,
Message Queuing, taking into an account new features from
upcoming .Net 2.0
Centralized management tool was developed on the top of real
time databases and enterprise level servers. Information related
to customers, applications, hardware is registered and maintained
on the enterprise server. If records modified on the central server,
specified system information gets automatically propagated to
the production databases through the custom build replication
mechanism. The second version of the tool has been rolled out to
production.
Instruments: C#, .Net Windows Forms, ADO.Net, custom
controls based on the .Net DataGrid control.
Designed, developed, tested, tuned up for the speed and
deployed real time databases, instances of which are intensively
used in production by high volume speech applications.
Speech applications, written by app developers in Jscript,
communicate with the databases through ADO. Speech
applications receive and register incoming calls in real time mode.
Outbound calls are controlled by the jobs and schedules
subsystems.
Wrote stored procedures, functions, triggers, tuned up indexes,
created DTS packages to import and export data, scheduled
backup tasks, tried out all types of replication, scripted custom
one.
Platform: SQL Server 2000 Enterprise edition.
Developed distributed enterprise application which allows human
operators to post-process thousands of call sessions daily. It
allows transcribing speech application sessions in question, such
as not recognized phrases or other real time errors. A very similar
product can be seen here: iTranscriber Main distinctive feature is
the unified .Net hosted application framework which allows fast
creating and integration of a specific logic in form of a separate
plug-in. Each plug-in conforms to the standard interface and is
similar to providers in .Net 2. Plug-ins are loaded in run time from
a separate assembly DLLs by .Net Reflection(C#) mechanism. Each
plug-in can in-capsulate specific business logic or can be used to
process session data for a set of speech applications. Uses
embedded Windows Media Player to playback the audio files.
Session information and files location retrieved from production
databases. Internet Explorer clients work simultaneously due to
custom locking and authentication mechanisms.
Instruments: C#, ASP.Net, ADO.Net, WebServices, SQL Server
2000
Designed, developed, thoroughly tested and implemented a
distributed application which transfers audio (wav) files and
session XMLs from real time production computers to the
designated file storages. Works in production 24x7 and by
centrally managed schedules.
Instruments: Visual C++ 6.0, ATL template classes, XMLDOM,
ADO, multithreading. Windows service version available.
Management tool released in 2 versions: classical ASP (XML +
XSL) and .Net Windows Forms(C#).
Developed specialized COM server to quickly scan file system
directories with hundreds of thousands files. Improved
performance of existing scripts by replacing the standard
FileSystemObject.
Instruments: Visual C++ 6.0, STL, ATL classes, Windows API, MS
XMLDOM
