The CCNP certification (Cisco Certified Network Professional) indicates advanced or journeyman
knowledge of networks. With a CCNP, a network professional can install, configure, and
operate LAN, WAN, and dial access services for organizations with networks from 100 to more
than 500 nodes, including but not limited to these protocols: IP, IGRP, IPX, Async Routing,
AppleTalk, Extended Access Lists, IP RIP, Route Redistribution, RIP, Route Summarization,
OSPF, VLSM, BGP, Serial, Frame Relay, ISDN, ISL, X.25, DDR, PSTN, PPP, VLANs, Ethernet,
Access Lists, 802.10, FDDI, Transparent and Translational Bridging.
Strong communication, intuitive and IT/IS skills. Proven ability to work efficiently in both
independent and team environments. Adaptable and efficient in work situations with changing
responsibilities.
Strong work ethic based on Christian moral values.
Work Experience
As a Student Engineer and later as a Graduate Engineer (1989-1992) I was attached to
Tel*One (Formerly PTC) Telecommunications departments including:






Carriers and Microwave Transmission
Satellite Communications
Data and Telegraphy
External Plant
Development Lab
Electronics and Telephone repairs
In the first half of 1993 I worked in the Cable Planning National department where I planned
the optical fibre links linking the old CABS HQ in the city centre to the new HQ in Northridge
and another linking Harare main Exchange & Zimbabwe Broadcasting Corporation (ZBC)
equipment room at the National Sports Stadium. It was from the sketches I made on the later
project, that the drawing office produced the actual layout of the cabling. Before this we had to
rely on a proposed plan for the National Sports Stadium, not what was actually on the ground.
Between mid 1993 to 1997 I worked in various capacities including Acting Head Software
Support Centre and Acting Head Principles and IT Training at the PTC Telecom College. The
duties involved the Operation and Maintenance of the TRN/SSC Fujitsu F150 exchange and the
running of Digital Switching Courses. The software Support Centre (SSC) was used for
generating Exchange Office and Subscriber Data and as a test bed for software patches before
launching them on the “live” exchanges.
From mid 1998 to the end of 1999 I worked as Senior Lecturer Principles Training and was also
a Windows NT 4.0 LAN administrator responsible for PC repairs and Software upgrading.

Major achievements
MBCA LAN/WAN Redesign
In the few months that I have been with MBCA, I have managed to come up with a redesigned
topology of the network with a strong emphasis on Security and Availability through provision
of backup network elements. The design has been approved and implementation is in the
process of completion. Below are some highlights:
CEPECS (CD1) System
My knowledge of the Internet infrastructure in Zimbabwe has enabled us to connect to the CD1
system at speeds that surprise even the implementers of the system at RBZ. I have received
several calls from other banks who want to know how we have done it.
4
SWIFTNET FIN Migration
We are in the process of upgrading to the new SWIFTNET FIN network. The process of applying
is mostly online, and again because of previous experience it has been easy liaising with SWIFT
and the network provider, Equant/SITA and I am sure the upgrade will be smooth and on time.
Bulawayo Office
When I came on board, there were intermittent connectivity problems with the Bulawayo
office. Almost every week there was this or the other problem. Bulawayo users could not
access the Internet and even the MBCA Internet Banking Site hosted here on our servers. With
the coming of the fibre link at the beginning of the year there has only been two incidents
when the link went down, one of which was as a result of a scheduled maintenance by
Powertel. Bulawayo users can now browse just like the Harare users, and a CD1 inputter’s
machine has been “wired up” to speed up access to the RBZ site.
Security Policy
Apart from the HR Computer usage form there really has not be a formal Network Security
Policy in place. I managed to come up with some policies that should become enforceable at
the beginning of 2004.
Internetwork Troubleshooting
I have been in the “Internetworking trenches” long enough to know what works and what
doesn’t. When I came on board I was actually surprised as why things were working at all
because of the many mis-configurations that were on the network elements. I have worked
hard to resolve these and we have had no need to outsource any Internetworking issues as
used to happen before. On the contrary, I actually assist in resolving problems at our ISPs. As
far as I am concerned I could easily be the most qualified Network and Security professional in
the country.
Previous Achievements at Tel*ONE
Project Manager for VoIP and ISDN
I was Project Manager for two projects introducing Voice over IP (VoIP) in Zimbabwe. The two
projects were with the market leaders in IP Telephony, iBasis and ITXC. Both companies were
quite impressed with the level of expertise we have in Zimbabwe as compared to other African
countries outside South Africa. iBasis was so impressed they felt it not necessary to send their
own field engineer to set up and install the VoIP gateway. The projects involved working with
other departments like Electrical Power and Air Conditioning (for provision of power), Projects
Installations (for installations of E1 coaxial cables), Switching (for switch configurations),
Technical Support Unit (for Channel allocations), Transmission and Earth Station (for the
provision of IP E1s), and Services and Sales (for the provision of telephone lines for dial up
backup connectivity).
I managed to test ISDN connectivity in Harare and Bulawayo (ZITF 2002). I could easily be the
only person in Zimbabwe with practical experience of ISDN Dial on Demand Routing (DDR).
ISDN is alive and well in a few exchanges in Harare and Bulawayo, however Tel*ONE has not
marketed the service well.
Participation at International and national exhibitions
5
I pioneered participation of Tel*One Internet Services at exhibitions like the Zimbabwe
International Trade Fair (ZITF), Harare Agricultural Show and Zimtel. This involves everything
from the application of data leased lines and telephone lines, setting up and configuration of
LAN and WAN components to the actual presentations/demonstrations of dial up and leased
line Internet connectivity and other services.
DNS Tender
I led a team in putting up a Tender bid for the provision of DNS services involving the .zw cc
Top Level Domain(TLD) and its subdomains. The General Manager was impressed and Tel*One
was set to win the contract for provision of DNS services in Zimbabwe. Unfortunately POTRAZ
abandoned the Tender procedure in unclear circumstances.
In addition to the above, Tel*One embarked on an Internet Expansion Project (with the help of
Global One – now France Telecom Long Distance) that was to increase the number of PoPs
(Points of Presence), expand the Internet backbone and saw Tel*One become a fully fledged
Internet Service Provider (ISP). My area of speciality was the Installations and configurations
of the LAN and WAN components (routers, switches, hubs, CSU/DSUs etc) as well as Web Sites
Hosting. I led a team to upgrade the Gweru, Masvingo Kwekwe, and Chinhoyi PoPs.
