Professional experience

- Senior Software Engineer / Architect                                      March. 2004 - Present

Responsibility: -

• Tools being used: Visual-C#, .NET Framework 2.0/3.0, Visual C++, Threading, MSMQ, UML modeling using Enterprise Architect, ADO.NET, ASP.NET, Win-Forms, XAML, Smart-Clients, WPF, Web-Forms, WF, XML, Web Services, Web Services Enhancements 3.0 Service [WSE], WCF, SOAP, Window Services, Drivers, MS-SQL 2000/2005, IIS-6.
• Work involves, requirements analysis, making use cases and realizing them, making prototypes, sequence diagrams, modeling class diagrams and implementing using visual C#. Developing service oriented architecture [SOA] so lots of interfaces are being developed in xml-web-services using SOAP protocols / SOAP messaging. We have a multiple tier system, Presentation, business and data layers, where data-layer is heavily using ADO.NET to communicate with the back-end MS-SQL2000. The Web-services consumers range from thick clients, Win-forms to Web-forms [ASP.NET] and smart-clients. Developed lots of trend diagrams, and imaging stuff using GDI+. All the messaging and load balancing is done via SOAP-MSMQ. We are using Web Services Enhancements 3.0 Service [WSE-3.0] that helps create interoperable Web services with advanced Web services features like secure your messages using digital signatures and encryption, send attachments, route messages through intermediaries, and more. Also using various design patterns like Façade, Model-View-Controller [Observer], Proxy and Factory patterns. Also using Application Blocks for .NET for Caching, Configuration, Data Access, Cryptography, Exception Handling, Logging & Instrumentation and Security Application Blocks. Used ASP.NET 2.0 Memberships, Role Management and Authentication.

·         Developing a complete backup solution in .NET 3.0 that is highly scalable, secured, and robust and at the same time maintainable. Involves developing web services using Windows communication foundation (WCF) for publishing interfaces for different remote backups / restores like for FTP media etc., and building business components for facilitating different facades for encrypted backups and also utilizing LINQ for the data-access layers. The interfaces are published via Facades and are configurable and are based on the contract first principle that is all the business objects are conformed to xml Schemas (xsd). Also developing WinForm based Smart-Client as consumers using Windows Presentation Foundation (WPF) and XAML. The forms all uses the Data-binding features provided by the .NET. While developing the application developed all the workflows required, using Windows Workflow foundation (WF) and then implemented all the scenarios required for backups and restore using C#. Highly customizable for all the clients as a consumers for the backup/restore web services.

-         Lead Architect                                                                 Sep. 2003 – Feb. 2004

Responsibility: -

·         Tools used: Visual C++, Visual-C#, .NET Framework 1.1, MSMQ, UML modeling using Enterprise Architect, ADO.NET, ASP.NET, XML, Win-Forms, Smart-Client, XML-Web Services using ASP.NET, MS-SQL 2000, Win-XP, IIS-5.1

• Architected, designed and developing distributed Task manager for thecompany Product Market-Master. The Software is composed of a smart client [Winforms] those records and controls the task scheduled and consumes two ASP.NET XML Web services One Web service is responsible for data access provides a consistent interface for data access layer using ADO.Net and provides serialization into XML format. The Other Web service implements the Business Logic, like how to deal with the daily, weekly, and monthly tasks etc. Since the Project was of Asynchronous and distributed nature, The Task Queuing is done using MSMQ.NET. This involves sending / receiving transactional Messages, Prioritization, and Journaling of the queues for Tracing and history management. Also all the messaging across different components is done using the in-house MSMQ framework. This way reliable loosely coupled and more cohesive reusable components were developed. UML is used for all the documentation like use-cases, Class diagrams, sequence diagrams and State Charts.

Lead Analyst & Developer Responsibility: -

• Tools used: Visual C++/MFC/UML, WinNT, ODBC, SQL
• Developed IoLyzer Software
  • Designed & Developed Interface software IoLyzer in VC++/MFC for an embedded system, being used in the synthesis of embedded systems, for a US based Company RDLabs.com.
  • Here are some details regarding its development:
  • Created UML diagrams from use-cases, class-diagrams and interaction diagrams.
  • The GUI is MDI based and the software patterns applied in building this software are Factory, composite, observer, and strategy and iterator patterns.
  • The IoLyzer has four main functions: Digital Logic Analyzer, Digital Pattern Generator (Patterns Playback) EPROM emulator, PCI Bus Monitor. I have implemented Both Digital Logic Analyzer and Playback part. The Hardware has four pods with each has 32 channels in it.
  • What the program does it interacts with the hardware and Instead of the user being forced to specify more complicated triggers this analyzer will capture everything and let the software sort it out. Say when certain trigger or patterns is occurred, it grabs the data from the Pods and displays it on the Screen. The Engineer then goes through the details of the channel for synthesis as well as troubleshooting.
  • The software has the option to set delays, trigger patterns and other Syntheses Related information. The software has the capability to play already recorded pattern and display that on to the screen.
  • The IOLYZER combines a high-speed 50/100 MHz logic analyzer with great memory depth 32 Meg deep and width of 128/64 channels. Combined with its differential storage capability it provides the engineer the ability to store every event.
