SELECTED  PROJECTS

1.  CURRENT MAIN PROJECT (2006-- ) (Zimbabwe)

I am the technical lead ,architect and principal developer in a project to build a multichannel voucherless prepay recharge SOA platform. Most of the platform  components are ready. This project has also enabled me to master building wireless client applications on Java enabled  phones  using J2ME .
The extensible middleware platform has a JBoss engine and its persistant layer is managed by Hibernate interfacing MySQL. Recharge servers targeted are
1.the Comverse Prepay HIA billing system interfaced via telnet components, done.
2.the Comverse Customer Care Web Services server interfaced via XML-SOAP,done (www.comverse.com) and 3. the Ericsson AIR Recharge System 3.0 via XML-RPC


















3.  Bank ATM- Prepay mobile  Web Services  integration, 2005
(Zimbabwe)
The mobile operator uses the Comverse (www.comverse.com)  GSM Prepay Billing  platform,  whose public interface was recently re-implemented as a SOA web service . I had to redesign my earlier integration components to the ATM network. Main challenge was implementing Java Web Services with security for interoperability with the upgraded prepay platform which is  based on .NET Web Services.
The Prepay Web Service integration point was just its Web Services Description Language  (WSDL) file.

4.  ATM-prepay mobile integration, 2000 (Zimbabwe)

I was the architect and developer of Africa’s  first  bank ATM-to-Prepay phone instant (voucherless) recharge integration solution. This project had complex network and software integration challenges which we met  within  six months.
The integration components initially were bult on  standard java  and later early J2EE versions. I built the interface to the base24 ATM/POS authorization host, received ISO8583 messages, parsed them and translated them to prepay host commands send via a software telnet session.I also built the java telnet client components from scratch
