  • Database View/Query/Reporting System (contract for Visual Interactions)

Proposed top-level software architecture for a new business intelligence product. This included a conventional fat client architecture based on Visual C++ and Visual Basic, as well as a thin client architecture with Microsoft ASP.NET, Web Forms, and C# components. Also created object oriented and thread-safe designs of several core services for low-level database access, generic query handling (SQL), metadata handling (import, storage and retrieval), security (authentication and authorization for sessions and data access, including content-based security), and general utilities. Led the work of a team of developers in the implementation of several of these services, as VC++ DLLs; all work was completed on schedule.  The work included use of UML, COM /ActiveX, VC++ (with C++ Std. Library), VB, MS .NET and VS .NET (Beta 2), OLE DB, ADO / ADO.NET, ASP / ASP.NET, SQL Server and XML / XML schema; also various Microsoft tools for build management.

  • Object Oriented Design and Database Consult (for Instrumentation Laboratory)

Mentored a team of developers regarding object oriented analysis, design and development for a high-end medical analyzer product. Also provided research and recommendations on back-end database architecture and products, with a focus on high performance data access with Microsoft SQL Server and its standalone Desktop Engine (MSDE). This work was for the Windows platform, and involved UML, Visual C++, MFC, etc. Data access technologies such as streamed XML, ADO and ADO.NET were carefully evaluated.

  • Reactor Control System Host Interface (contracts for CXE Equipment Systems)

Upgraded a 16-bit SECS/GEM interface to the latest 32-bit technology, for use with the client's silicon reactor control system products. This work targeted Windows NT and Windows 98 platforms, involved a large amount of work with legacy code, and called for integration with GW Associates' SECS/GEM libraries and a WonderWare user interface (as well as a diagnostic interface provided by Alitech). Also provided documentation, test scripts (for SecSim Pro), and software build automation scripts.  Re-hired several times to support new features, reactor models, and multiple Windows platforms.

  • Semiconductor Fab Air Monitor (contracts for Extraction Systems)

Designed and implemented a complete OEM software package to provide control, monitoring, graphical user interface and SECS/GEM interface for the client's amine impurity analyzer for the semiconductor fabrication industry. 

Focus areas: Reviewed software requirements, and long term goals, for this new product; recommended operating system and modular software architecture (using COM, Visual C++ and MFC); developed an object oriented design (with UML). 
Quickly implemented base features, and provided a shippable release within two months, including: sampling control, data acquisition, alarming and logging (implemented within a multithreaded Windows NT Service, and COM component), which interfaced to a user- friendly GUI module with dynamic bar displays, dynamic data charts, reports and journal.  Implemented a serial I/O interface with OEM hardware, with configurable input modes. Designed and implemented a SECS/GEM interface for the equipment -- packaged as an optional COM component -- to allow communication with host computers in semiconductor facilities; certified for SECS/GEM compliance using third-party test scripts (SecSim Pro). Re-hired to create additional features, including: advanced scheduling, enhanced alarm and control, diagnostic displays, enhanced security, new I/O hardware, increased number of sample locations from 10 to 100, auto-calibration scripts -- all fully configurable from the GUI; Alitech also developed InstallShield-based setup programs, on CD-ROM, and assisted the client and their customers with pre- and post-sale technical support.
