Staging Environment for Zebra MC93/94 Handheld Scanners

Overview

Independently designed and implemented a robust, scalable staging environment for Zebra MC93 and MC94 handheld scanners, supporting seamless mass deployment across multiple service locations. This solution streamlined device provisioning, reduced manual configuration time, and ensured long-term maintainability.

Key Contributions

Automated Deployment Framework: Configured and optimized Zebra’s staging tool to enable zero-touch provisioning. Devices are now deployed effortlessly by scanning a single barcode, eliminating manual setup and reducing errors.
Custom Android Work Environment: Developed and implemented a secure, work-specific Android lockdown using an MDM. Designed an intuitive UI while enforcing strict access controls to maintain compliance with business requirements.
Ongoing Maintenance & Optimization: Manage all layers of the deployment lifecycle, including staging configurations, UI enhancements, and work profile updates. Regularly refine system parameters to enhance performance and security.
Update Management & Version Control: Established a structured repository for maintaining a catalog of compatible updates. Oversee the integration and rollout of OS updates, security patches, and application enhancements to ensure operational stability.
Enterprise-Level Scalability: Successfully deployed and actively manage dozens of devices across 18+ service locations, maintaining uptime, security, and performance.

Zebra Label Printer Integration with IBM i Operating System

Overview

Designed and implemented a custom configuration for Zebra label printers to seamlessly integrate with an IBM i operating system environment. This project involved overcoming compatibility challenges by modifying firmware and leveraging vendor tools to ensure proper communication between the IBM i system and the new hardware.

Key Contributions

Custom Firmware & Print Language Configuration: Modified Zebra printer firmware to support Intermec Print Language (IPL), enabling compatibility with the IBM i system, which natively outputs in IPL rather than Zebra’s default language.
Vendor Tool Utilization: Leveraged Zebra’s proprietary tools to build and fine-tune a tailored configuration that met the organization’s specific printing requirements.
Network & Deployment Optimization: Configured the final units for network operation, ensuring seamless connectivity and reliable performance across multiple locations.
Enterprise Rollout & Maintenance: Successfully deployed and continue to maintain these printers across 19+ service locations, monitoring performance and resolving any integration issues as they arise.

Payment Processing System Modernization

Overview

Led the transition from a legacy payment processing system to a modern, self-hosted solution, enhancing transaction reliability, security, and efficiency across all service locations. This project required close collaboration with the payment processing vendor to implement a fully integrated system, including hardware, software, and network infrastructure.

Key Contributions

Self-Hosted Payment Infrastructure: Designed and deployed a self-hosted payment processing environment, ensuring seamless operation across all service locations while maintaining compliance with vendor-specific network requirements.
Hardware & Software Integration: Configured and optimized card reading devices, a secure web-based payment portal, and backend processing systems to facilitate both in-person and manual-entry transactions.
Testing & Deployment: Conducted extensive testing and fine-tuning of all components to ensure smooth payment processing, minimizing downtime during the transition from the legacy system.
Ongoing Maintenance & Optimization: Continuously monitor and refine system performance, troubleshooting issues and implementing improvements to maintain a reliable and efficient payment processing workflow.

Windows Imaging & Workstation Deployment

Overview

Designed, built, and deployed a dynamic Windows imaging solution to standardize and streamline workstation provisioning across the organization. This project involved architecting a flexible, virtualized environment capable of supporting multiple hardware generations while ensuring seamless integration with enterprise applications, security policies, and user-specific configurations.

Key Contributions

Dynamic Windows Imaging Architecture: Engineered a highly adaptable, hardware-agnostic Windows image that accommodates multiple workstation models. This eliminated compatibility issues, reduced deployment time, and ensured a uniform computing environment across all service locations.
Virtualized Build & Testing Environment: Leveraged a controlled virtual environment to develop, refine, and rigorously test the image before deployment, allowing for rapid iteration, debugging, and long-term maintainability.
Automated Deployment & Configuration Management: Implemented a structured deployment workflow to automate workstation setup, integrating essential commercial applications, security policies, and user-specific software configurations without requiring manual intervention.
Collaboration with Technical Support Vendor: Coordinated with external technical support teams to ensure all software dependencies, licensing requirements, and user permissions were properly implemented, minimizing post-deployment troubleshooting.
Remote Workforce Enablement & Security Hardening: Designed and integrated additional security layers, including VPN solutions and encrypted authentication protocols, to support remote users requiring secure access to IBM i operating system applications.
Scalable Deployment & Ongoing Maintenance: Successfully deployed and actively maintain workstations across multiple locations, refining configurations based on evolving business needs, security requirements, and performance benchmarks.

Tailored RDP Environment & POS System Deployment

Overview

Developed a custom Remote Desktop Protocol (RDP) environment and a specialized Point-of-Sale (POS) system tailored to the organization’s front-end sales and operations. This project, executed in close collaboration with a technical service provider, required designing a secure, high-performance infrastructure that seamlessly integrates with both vendor applications and the IBM i operating system.

Key Contributions
