Sandata Technologies, LLC, Inc., Port Washington, NY 1996-2012

Programmer/Analyst, Team Leader, Application Developer

Designed, developed and maintained several applications in .NET(C#), C/C++, Oracle PL/SQL, OCI, Nuance ASR 8.5 and Java, using Servlets, AJAX, JavaScript, XML, ASP, JDBC, ODBC and various IDE – Visual Cafe, MS Visual Studio 6/2005/2008, Eclipse, Talend( ETL ) and platforms – OS/2, Novell Netware, HP-UX, Red Hat® Linux, Windows NT. Projects includes:

“SANTRAX® system” (1996-2012) - C/C++ based applications on OS/2(1996-2007). It receives phone calls and provides an IVR and Voice Recognition for callers. This multithreaded and a multiprocessing system using all kinds of IPC (interprocess communications) methods: queues, pipes, shared memory, mutex and event semaphores. This flexible system supports telephony protocols of different companies such as MCI, AT&T, WorldCom, Frontier, LDDS, QWEST, and Global Crossing. The system is scalable and is the major company’s product since being developed. The system tracks phone calls and collects data for off-site locations that used in the home health care industry. Key players at all stages of this project. This system was rewritten (2007) with C++, VXML on Red Hat® Linux platform.

“A835” (2012), “997/999” (2011-2012). This application realizes automated handling of EDI-X12 form 835 and 997/999 (Windows NT, Talend and SCO UNIX).

“Inbox4ALL” (2006-2012).This multi-threaded application allows import data to SANTRAX® System from different scheduling system such as Carelink, Misys etc. (Java, JDBC, Windows NT).

“Check Calls (2003-2012)”. This application releases alternative method calls delivery from calls servers to Oracle data base (Java, JDBC, XSLT, XML parsing, Oracle PL/SQL, Red Hat® Linux).

"Account Manager"(2002-2012). This application was designed mostly for client relation personal. It is a visual tool to manipulate the SANTRAX®’s control information in the ORACLE database by providing different levels of access (C++, OS/2). Version 2002 has been written in JAVA using servlets, JDBC and dynamic HTML. The last version of Account Manager (2010) has been rewritten using ASP.Net (C#), Oracle G10, G11.

“ET2ORA” (2002-2012). This multi-threaded application allows import customer’s data (clients, employees and schedules files) in several of different (about 40) formats into Oracle data base. (C with Oracle OCI, Windows NT).

“CheckDNIS” (2007-2010). Calls servers were designed to work in standalone mode – they should receive phone calls regardless of problems which may occur in other parts of the system. That was implemented in this client-server application. Using sockets communication, call servers periodically request control information on how to handle phone calls from the server. Upon receiving the request, the server checks for updates the central database and returns all necessary information(multi-threading, C++, Red Hat® Linux, MySQL, ORACLE, ODBC)

“Inbox4VNS” (2004-2010). Application releases interface for data exchange between VNS agencies and SANTRAX® System. I was a solo developer of this project (Java, JDBC, Windows NT).

“Find Calls” (2003, 2010). Another tool for client relation personal created in JAVA using servlets, JDBC and dynamic HTML. This tool helps fast find all calls that specific client have made to the SANTRAX® for any period of time (JAVA, JDBC, Servlets, ASP.NET, C#).

“CALLSREP (2001-2010)”. Statistical reports (CA-daily and AN-weekly/monthly/quarterly reports). Several reports were created for management's needs, billing purposes and future upgrade of the SANTRAX® system (C++, OS/2, Java, JDBC, Oracle PL/SQL, Windows NT).

“NET2BTR” (2000-2010). Application allows deliver customer’s data from several FTP servers to inbox for each account on application server. This application also delivers some reports from applications servers to FTP (SFTP) servers for client’s pick up (C++ with OCI, Windows NT).

“SimRCApp” (2007-2008). This is server’s part of client-server system for on fly voice recognition during the call in SANTRAX® system. This application allows caregiver also enter data during the call by voice and not only by using phone keypad. Using sockets communication, clients from call servers (RHL) sends request to server (Windows NT) for voice recognition. Result of voice recognition returns to client (Multi-threading, cross platform, C++, Oracle OCI, Nuance ASR 8.5, Windows NT, Red Hat® Linux).

“Voice Messages Broadcasting System” (2004-2007). System allows a manager to prepare a phone messages for particular off-site employees (C++, OS/2, VXML, Red Hat® Linux).

“SysMon” (1998-2007). A daemon, which periodically analyzing calls, error messages and statistical information and sending messages (alerts) to an operator in case of errors and any system degradation for any system component. (Java, JDBC, Red Hat® Linux).

“Transcription Services” (2005). Application allows caregivers to dictate notes over the phone for subsequent transcription. Transcript is available for customer as MS Word document on Sandata web site (C++, OS/2, VXML, Java, Windows NT, Linux Red Hat®).
