Work & Experience
Core Infrastructure Architecture: Engineered, built, and provisioned the foundational IT hardware networks across 36distinct regional business hubs, establishing baseline switching structures, secure wireless links, and physical perimeter hardware configurations. Storage Systems Engineering: Configured and deployed scalable, enterprise-grade IP CCTV camera arrays across multiple branches, managing the precise zoning of Power-over-Ethernet (PoE) switches and Network Video Recorder(NVR) storage volumes to secure 100% data capture reliability. Facilities Layout Design: Evaluated technical blueprints and facility architectural diagrams to map physical machine placements, network node distributions, power path lines, and environmental camera angles prior to building new business nodes. Asset Lifecycle Management: Spearheaded a comprehensive, centralized registry framework for over 200 hardware devices and enterprise licenses, verifying that hardware baselines achieved absolute compliance and zero licensing drift. Performance Tuning & Analytics: Reviewed network transit speeds and monitored cross-site hardware nodes via automated ticketing tools to spot and eliminate structural data flow constraints, boosting system-wide operational uptime to 99.9%. Vendor Management & Procurement: Directed the technical review and technical procurement operations for replacement enterprise hardware, negotiating terms with equipment vendors to stay within rigid cap-ex constraints.
Access Control & Identity Governance: Managed strict identity verification mechanisms across a 40+ daily ticket stream, dealing with account lockout remediation, Multi-Factor Authentication (MFA) token resets, and high-tier credential authentications. Terminal System Deployments: Coordinated the remote network staging, IP allocation, and firmware optimization steps for 100+ new terminal nodes, securing stable connectivity lines with central transactional infrastructure. User Acceptance Testing (UAT): Spearheaded technical end-user simulation testing for crucial core platform updates ,isolating software issues and documenting system errors for escalation to backend development engineering teams.
Enterprise Hardware Migrations: Actively assisted in a high-stakes migration from legacy z14 infrastructure to next-generation z16 platforms, directly managing input/output (I/O) configurations, hardware definitions, and Hardware Management Console (HMC) environments. High-Availability Operations: Supervised the deployment, maintenance, and fine-tuning of enterprise operating systems and verified third-party utility applications across a multi-LPAR Parallel Sysplex topology, guaranteeing a99.99% baseline uptime for high-volume transaction environments. Disaster Recovery & Redundancy: Designed, updated, and executed annual enterprise-wide Disaster Recovery (DR)simulation drills; audited replication pipelines to successfully restore primary banking subsystems within strict, predefined Recovery Time Objectives (RTO). Production System Monitoring: Maintained continuous oversight via master operating consoles, intercepting critical hardware warnings, system alerts, and memory allocation bottlenecks to initiate early-stage containment and preventative system tuning. P1/P2 Incident Command: Hosted high-priority technical "War Room" escalation calls during critical production outages, collaborating dynamically with database and network engineering cells to safely restore interbank payment flows and real-time payment settlement engines. Systems Maintenance & Onboarding: Standardized internal documentation outlining initial program load (IPL)routines and hardware failover methodologies; utilized this material to train and onboard 4 junior system administrators into the core operations rotation. Audit & Lifecycle Tracking: Leveraged ServiceNow and JIRA platforms to execute strict version controls on production systems and generate comprehensive resolution logs following internal infrastructure security audits.
Reconciled daily cash positions for a network of ATMs, ensuring the physical cash inventory matched the Core Banking System totals.- Led investigations into customer claims (e.g., failed cash withdrawals, deposit discrepancies), successfully identifying hardware malfunctions (bill jams, sensor errors) to validate or deny claims.
