• Looking after entire food factory machinery used to produce frozen potato chips. both mechanical and electrical from PLCs and control panels to generators to refrigeration systems to water treatment to packing machines.
• Implementation of new setups/tools/modifications to assist in maintaining and running machinery better.
• Co-ordinating and training both electrical and mechanical teams on complex technical aspects of machinery.
• Food safety measures and procedures ISO22000

List of machinery/systems under my care :-

• Ammonia refrigeration system (-20 degrees freezer rooms, -40 degrees blast freezing, -12 degrees cold storage and packaging area). condenser system and water treatment.
• Steam boiler and thermal oil burner (LPG gas fueled and diesel fueled).
• Water supply boreholes, pumping systems, filtration, treatment, water softener, waste water management
• Production line from raw potato sorting and conveying, steam peeling, blanching and air heating and drying systems, fryer line, blast freezing and multi-head weigher packing machine.

• Trade kings Zimbabwe is a powder detergent manufacturing plant with a 5T/hr spray capacity and 8 packing machines. Normal production was 100T of packaged powder per day.

Maintenance engineer position (April 2021 - Apriil 2022)

• Reduced downtime through efficient troubleshooting and root cause analysis of complex equipment failures both electrical and mechanical.
• Reviewed technical documentation to complete equipment maintenance and repair, planned preventative maintenance schedules.
• Critical spares sourcing purchasing for both electrical and mechanical systems.
• Redesign of systems for better efficiency and accuracy e.g. load cell redimensions and calibrations to allow for a more accurate chemical dosage saving company thousands of dollars per month on overconsumption of raw material.

Process production manager position (April 2022 - Nocv 2023)

• Management of the machinery and team of 50 producing the the powder detergent up to conveying to packing section. 24 hrs a day production 5 days a week.
• Came up with raw material tracking and management systems, which was so effective that thousands of dollars was able to be saved if required. Control levels of raw material consumption was +/- 1% accuracy.
• Repaired and improved many technical systems related to production of detergent.
• Introduced effective Preventative maintenance schedules to reduce production downtime.

• Maintenance of All Huawei Datacom switches and routers at MTN Zambia Network (Maintenance) (200+ routers, switches & firewalls)
• Most time has been spent on leading project and technical setup of a new IP radio access network (an additional 250 routers throughout MTN Zambia Network). IPRAN complexity - ISIS, BGP VPNv4, MPLS, VRF (Huawei Seamless MPLS solution). This solution involved moving MTN mobile access network from old transmission layer 2 only setup to a complete layer 3 network. This included end to end service migrations from core nodes (RNC,BSC,SGW,wireless management servers) all the way up to remote wireless NodeB, EnodeB and older 2G technology sites.
• In this project all aspects from design, planning, resource maangement, installation, configuration, commissioning and service migrations were carried out
• Along with project rollout normal maintenance tasks, setting up resilient IPRAN network, expansion and integration of complex services onto client network like QoS on layer 3 network.
• Firewall configurations, internet gateway adjustment for multiple ISP providers,
• DPI setup and optimization according to clients requirements.

Double Role - 1 Network operations Team lead

• Leading & Mentoring NOC team (team of 6) for creating innovative processes/systems for effective monitoring of network
• Training NOC team toward essential areas and functions of entire network, guiding and creating skill-sets and developing knowledge far beyond just network monitoring.
• Being a lead in the event of complex network incidents/outages.

Double Role - 2 Network operations Back office engineer

• Ownership&responsibility of All switches,routers(ZTE) & perimeter firewall (DPTech) for core network. Inclusive of their management systems (ZTE Net-Numen management system/OSS). Including new configurations on all switches and routers - OSPF,BGP, Routing, VRF routing, EnodeB IP planning.
• Maintenance of Radio access network management system (ZTE netnumen).Both Physical server and OS platforms.
• IP layer configuration for EnodeB. For interconnection to core network & EnodeB management system.
• Recovery of ZTE Radio access management system with no guidance,documentation or support (Linux based server - network configs,Databases,drive mounts,symlinks & ZTE proprietary software repair). System was fully recovered.
• POC project - Integrating Peer app data content Caching system from raw unconfigured out of box server. SOW Included configuring server, setting up network connections. Once up configuring routing of all necessary traffic in order for system to cache internet data content used by our clients, traffic to and from server. Both Bandwidth optimizer and Pure caching systems setup.
• POC project - Testing Fairwaves EnodeB, integrating EnodeB into Core network through oversease VPN. EnodeB was Tested successfully while EnodeB was in UK but connected to core EPC in Zambia.
• Overseeing firmware customization & correction of main wireless Handsets devices Vodafone had in market - MiFi device. Included detailed tracing on core to isolate issues for vendor to revise and correct.
• Product creation - Private APN solution (Configuration on PGW), packaged ethernet over LTE. Includes configuration of APN (PGW), routing on PGW, core switches and firewall. End to end setup

• LTE EPC mobile network front desk monitoring
• Monitoring entire EPC network (Radio access,core network and Switches&routers) ZTE software and hardware used
• Monitoring power infrastructure of a Datacenter (Generators - Cummins, UPS - ZTE, cooling systems - Schneider).
• Network Monitoring Systems development centralized system for entire network (VM installations, Network parameters and installation and custom configuration of software platforms - Linux based - Proof of Concept)
• Project management - Oversea and deploy realtime network monitoring system(Icinga NMS - from POC)
• Designing and implementing Reports for network KPI's.
• Troubleshooting and resolving client complaints.
