System Engineer à General Dynamics Mission Systems
  • Oman - Muscat
  • Je travaille ici depuis juillet 2017

• Design: Analysis of technical specifications and requirements, clarification of safety, reliability, performance, and risk management engineering. Development of functional design specifications, interconnection, signal coordination, termination, and block diagrams.
• Deployment: Building, commissioning, and integration of network systems and infrastructure.
• O&M: Incident management (handling incidents & restoring services), problem management (determining & removing the cause), change management (increasing the success rate of network modifications), and preventive maintenance (proactive fault detection and resolution).
• Pre-Sales: Responding to functional and technical elements of RFIs/RFPs with the required documents.
• Training: Development and delivery of product presentations, demonstrations, and materials.
• Project Management: Implementing the deliverables throughout the system development life cycle; translating the deliverables for executive communication and reporting.

Accomplishments:
 British Petroleum:
 Successfully completed the Telecom Field Integration project on time and schedule by managing delivery plans in conformity with required standards.
 Duqm Port Refinery:
 Successfully designed and implemented the company’s telecom systems including collaboration systems, including IP Telephony, Telepresence, and the Hotline systems.
 Built scalable and resilient IT solutions for the refinery (including servers, workstations, hypervisors, clusters, and resilient centralized backup) for the refinery.
 Shell Petroleum:
Successfully maintained the company’s telecom infrastructure.

Optical Transport Network & Operations Engineer à URS-AECOM (Seconded to Alcatel-Lucent)
  • Arabie Saoudite - Riyad
  • janvier 2002 à février 2011

• Implemented optical network operation & maintenance on behalf of Alcatel for Mobily.
• Coordinated understanding of the project and system requirements, fitted the scope into the operational roadmap.
• Achieved consistency and timely delivery of target solutions and validations over the whole project life cycle. Including commissioning, testing, integration, network scaling, legacy migrations, ‘cut-overs’, and element insertions.
• Performed effective proactive checks which resulted in early detection and resolution of threatening conditions before impact level.
 Achieved 99.99% system availability through monitoring and tracking of system performances as well as analysis and correlation of trends and patterns of behavior across the network.
• Managed incidents and impacts through effective collaboration and team working.
• Mitigated incident re-occurrence through detailed investigations, technical failure analysis, troubleshooting, fault-finding, and root cause analysis.
• Influenced business decisions through timely reporting and analysis of network KPI.

Accomplishments:
o Saudi Arabia:
 Mobily Network:
 Achieved 99.99% system availability by looping back learnings into service strategy.
 Reduced service MTTR by over 70% by replacing the repair process with a simplified initiative that speeded restoration and mitigated re-occurrence.
o Kuwait:
 Kuwait Ministry of Communication:
 Successfully completed an optical transmission project with the Kuwait Ministry of Communications that connected Kuwait with Saudi Arabia on a DWDM coherent system. Delivered this project on time and within budget.
 Reduced unplanned outages by over 85%, by facilitating early detection and resolution before impact level.

Optical Transmission Deployment Manager à Alcatel-Lucent (Nokia)
  • Nigeria - Lagos
  • janvier 2006 à juin 2006

• Increased Alcatel-Lucent enterprise value through the consistent achievement of target solutions, including commissioning, testing, and integration of metro SDH, Coherent and Non-coherent DWDM Terrestrial ROADM topologies:
 Built and implemented the nationwide Transport network for Globacom Network on time and schedule.
 Successfully implemented the Glo-1 DWDM submarine/subsea infrastructure from Nigeria to the UK (bases on Alcatel-Lucent 1620LM SLTE).
• Achieved over 99% availability by Successfully implementing configuration/ reconfiguration of survivability strategies (SNCP, MSSPRing, ASON, WSON, Y-Cable, OLP, OCH).
• Reduced cost and downtime by proactively coordinating operation and maintenance.
• Repaired and maintained network assets by tracing and resolving the root cause, shared learning, including preventive actions.
• Influenced cost savings by managing quality assurance programs including pre-deployment on-site evaluations, internal audits, customer surveys, and analysis.
• Increased team performance by negotiating agreements between deployment teams to clarify misunderstood directions and resolved conflicts affecting performance.

Accomplishments:
 Globacom Network:
 Built and implemented the nationwide Transport network on time and schedule.
 Successfully implemented the Glo-1 DWDM submarine infrastructure from Nigeria to the UK based on the Alcatel-Lucent 1620LM SLTE.
 Saved time and costs through identification, assessment, and resolution of pre-deployment dependencies.
 Secured zero fatality, achieved incident safety record.
