Infinity Technology Systems, Inc., Wappinger Falls NY (April 2007 to June 2011)

System Architect and Lead Developer

Primary job was to provide the overall technical direction and efforts to move a suite of customer facing asp.net portals, Windows mobile, and backend Windows desktop applications to an Enterprise Service-Oriented architecture for software as service solutions for multiple utility company clients. Detailed architectural and design efforts were to redesign and normalize backend client databases, planning the movement from MySQL to MS SQL Server, eliminating redundant business logic and data definitions across the various application silos (mobile, web, backend, database, etc.) by leveraging the .NET WCF API to implement an enterprise SOA, recommendations for effective use of technologies such as XML, SOAP, JSON, REST, etc.

Using C#.NET to build WCF Data Contract data models for application data.

Using C#.NET to build Windows Service Host applications for WCF Service hosting.

Using C#.NET to construct, test, and configure WCF Service layer.

Coded Service logic to interface with Windows Mobile clients for pushing scheduled field inspection data up to mobile field devices for field operations.

Coded Service logic for pulling completed XML/JSON field inspection data, parsing, validating and directing results to detailed operation specific process flows as well as persisting data into backend SQL Server database tables.

Using C#.NET MVC pattern and the Entity Framework, Linq-To-Entities to code transactional level data access and persistence from within various business logic components in the service layer.

Using .NET 4.0 MVC technology to implement and remodel older web sites for better maintenance, enhancements and performance.

Some of the secondary work accomplished was maintenance and enhancements to client facing web pages, design of mobile databases (SQLite – Android, SQL mobile –WinMobile).

The system was a GIS based Utility Management Field Asset Inspection and management system responsible for inspection scheduling, work assignment management, field capture of inspection data, and back-end recording and client reporting.

Once the centralized system was in place we were able to automate administrative and operational support for the system to clients and vendors directly which reduced the amount of manual data feeds and processes required responding to or managing field captured results.

Example: Assets flagged for repairs in the field were originally batched and fed to vendors and customers via outgoing data feeds, we would then wait for incoming data feeds to determine the resolution of such items.

The new paradigm implemented a set of repair services where repair items were exposed to vendors and client through a number of web clients.

Authorized parties could then clear repairs, resubmit item for field operations, or flag them for special processing.

Environment: C#, VS.NET 2005 - 2008, SQL Server 2000 - 2008, RDBMS, ASP.NET, JavaScript, SOAP,XML, WCF Services, WCF Rest based services (Android Clients), Windows mobile development, JSON, JAVA (Android Development), SharpMap, Google Maps, Linq, LINQ-to-Entities, SQLite (Android db)

Introcomp Business Systems, Inc., Middletown NY (February 1998 to 2006)

President Consulting, Contracting, IT Training, Commercial Software Development

Development of a commercial Document management and content management system (Prototype). The system was developed as a distributed solution using VB.NET and SQL server 2000 as the back-end data source. A flexible database component was designed using reflection to dynamically handle industry standard providers, and to provide support for component level transaction with the business layer of the application. The business layer of the application was designed to be totally encapsulated from the client applications to support single system deployment as well as a scalable server deployment. The business layer was constructed using VB.NET and .NET service components for component level transactions and to effectively manage stateless objects in the middle tier. The business layer handles document and data request for client applications as well as enforcing business rules and workflow logic. The interface between client applications and the business layer was implemented using .NET remoting and assemblies that expose business layer signatures. The current client application is a Windows based front-end designed to simply present and capture data and documents from the end user. Imaging was implemented using a third party product (Leadtools) for scanning and low level manipulation of images. Future efforts will include a web based client with a web based gateway to the business layer of the system.

Development of enterprise service components (Generic Data Access engine, User Interface component).

Development of a windows forms engine for developers. This is a VB.NET component that encapsulates and automates the construction of data entry forms for .NET windows applications. The component consist of a few intelligent abstract elements such as a base form, a base user control, and UI engine that encapsulates, standardizes, and manages behaviors in all data entry forms. Developers simply construct forms by inheriting these components and following some simple procedures and task. The engine has built-in abilities to manage form navigation, state management and dynamic hooks to business logic.

Design and development of a billing and customer management solution for a local commercial laundry customer. The system was implemented using VB.NET and MS Access 2002 with later conversion to MSDE SQL Server. Customer needed to automate the storage and retrieval of his customer data, account info, service agreements, and manage billing and invoicing of customers.

Designed a Windows based system that was constructed as a logically layered application (presentation, business, data) to support future needs for remote access to the system. The front end was constructed using a third party product (Netadvantage) for its rich user interface components. A single windows application with dynamic user controls was designed to create a robust user friendly presentation with simple navigation. Business logic was developed to manage, schedule and automate the billing and invoicing of customers.

Provided distributed application development training using Visual Basic 6.0.

Independent contracting and consulting. Conduct presentations, demos and discussions of the .NET platform for local companies looking at alternatives to RPG, COBOL, and legacy VB.

Provided distributed application development training using Visual Studio.NET.

White Plains, NY

Consultant (Short term contract)

Enhancement to third party Auto-Insurance application using Visual Basic 4.0/5.0

- Replaced proprietary front end consisting of VB 4.0 forms and Object Cobol API calls with native Visual Basic forms and logic to enhance performance and allow more flexibility in data capture and presentation.

Coded and tested middle tier modules written in Object Cobol.

- Modified proprietary logic used to interface the VB front-end application to middle tier components written in Object Cobol.

- Designed, and tested standard Class/Object modules for RDO connectivity and

access to SQL Server. This eliminated the number of developers writing

redundant and normally buggy data access logic and provided for a high level of

component reuse.

Designed and coded modules to retrieve DMV driver information from Equifax reporting service.

- Created Visual Basic front-end to accept user supplied parameters and driver information for potential insurance customers.

- Implemented MSMQ components using VB for asynchronous messaging between front-end inquiry process and Equifax reporting service.

- VB components were designed to pass inquiry data to queues to be used by mainframe applications and to process resultant data from queues populated by Mainframe programs.

- Mainframe CICS apps communicated with Equifax service center via LU.6 transmissions passing inquiry data. Resultant data from the Service was returned to MSMQ queues by the mainframe processes.

- Returned data was retrieved from Queues, parsed, formatted and displayed, printed or both for Customer service reps.
