I'm offering
Versatile, technically skilled and CCIE certified Network Architect with over 12 years’ experience in configuring, installing and troubleshooting system and network, supporting IT operations and driving IT projects that increase effectiveness, improving system performance and boost operational output.
Wherever I work, my goal is to count, add value and to make a difference. When there is a problem, I want to be the first to fix it. I love bouncing ideas off of my peers and learning from them as often problems aren't solved alone but more quickly and efficiently as a collaborative group.
I am always trying to find easier ways to do my work which is why I am keen to learn new skills around automation as the goal should be to work smarter, not harder. Through working alongside a colleague, him and myself were able to automate the creation of HLD/LLD design documents from 4-5 days down to 1-2.

job
Act as a SME and mentor to junior Network Engineering
Capita IT & Networks.
Birmingham, UK Oct 2018 - Present
Highlight:
● Led the initiative to automate the process of creating design documents - developed a spreadsheet which would auto-
populate the HLD/LLD documents and generate the CPE/Distribution device configuration while reducing the production time from 3-4 days to 1-2 days.
Responsibilities:
● Manage architecture, design and implementation of Cisco based network solutions while providing consulting to clients.
● Interact with clients, understand their requirements and accordingly provide solutions to overcome the challenges.
● Deliver HLD & LLD design documentation for a large LAN upgrade and refresh project of over 1000+ sites using
technologies like 4500-X switches, ASR9Ks & ASR920's routers, ISR4K and 897VA Branch routers, and Palo Alto 5250.
● Make decisions on suitable hardware per site and incorporate the same into the design.
● Manage supporting activities like bringing up L3VPN's over an MPLS Core, CE/PE provisioning to establish site access
to DC, ensuring correct path selection via BGP attributes.
● Build site switches and CPE configurations files and redistribute IGP protocols into the MP-BGP Core; deploy VRF Lite
solution across campus's network to segregate networks.
● Render technical governance to the Network team; provide inputs to technical designs provided by other teams.
● Operate in a technical advisory capacity on projects where requested to provide advice and guidance on a proposed solution
or assistance towards a resolution where issues have occurred.
● Act as a SME and mentor to junior Network Engineering staff. Drive the production and enforcement of network standards
and guidelines.
● Ensure that assigned projects are executed and completed within agreed time, quality, scope and costs parameters.

job
Lead Network Engineer
Atos.
Highlight:
● Analyzed and identified the reason behind slow transfer speeds between the hub and spoke sites over a DMVPN solution
even while using Cisco WAAS devices - the size of packets; investigated and enabled a feature on Cisco WAAS devices
which reduced the packet sizes and prevented the routers from having to fragment the packets, thereby increasing the transfer rates and ensuring customer satisfaction with the new transfer speeds.
Responsibilities:
● Rendered technical support across multiple Data Centers while working on secure government network accounts such as
the Home Office, Department of Working Pensions and others.
● Worked on various network technologies like general switching technologies (STP, VLAN), general routing technologies
(DMVPN, BGP, EIGRP, OSPF), Cisco security devices (FWSM and ASA), Juniper security (SRX and SAs), checkpoint
firewalls and F5 Load Balancers Operations
● Provided network technical input into business office proposals ensuring that the solution satisfies the client's requirements
and follows Atos standards.
● Led technical investigations during major incident and ensured prompt resolution of escalated incidents in line with customer SLA targets and technical best practices.
● Managed changes in line with customer SLA targets, group standards and best practices; consistently ensured compliance
with customer/group change management process.
● Prepared customer/team documents and updated/maintained according to customer/group process.

job
3rd Line Network Engineer
Ingeus Ltd.
Highlight:
● Analyzed and identified the reason behind lack of communication between the active directory servers which was preventing
DNS communication, NTP time synchronization between the servers and other issues. I found that the RPC ALG feature on a firewall was blocking the secondary TCP session that establishes after the initial TCP session and resolved this server
wide issue across the infrastructure.
Responsibilities:
● Monitored all WAN and LAN activities to ensure maximum uptime for users; designed and implemented new network
solutions and/or improved the efficiency of current networks.
● Diagnosed and fixed network/system faults, oversaw security of all systems.
● Managed the network and network devices (patching, configuration management, monitoring etc.), managed all firewalls
and network security devices to ensure ongoing compliance with security requirements.
● Created and maintained infrastructure necessary for the growth and the upkeep of network operations; identified and corrected mission critical infrastructure problems at optimal costs and in a timely manner.
● Monitored network performance to determine if adjustments need to be made; designed and implemented new network
solutions and/or improve the efficiency of current networks.
● Managed an IL3 official sensitive Data Centre network.
● Worked on Cisco Routers & Switches, Juniper SRX and Cisco ASA firewalls, Data Centre security devices, SolarWinds
NCM, IPAM along with multiple other SolarWinds suite of tools and Cisco ACS TACACS+ server administration.
● Provided technical solutions to improve business efficiency, quality or process while maximizing functionality.
