04. Some Things I've Built
Network Infrastructure Upgrade
A company-wide network infrastructure was upgraded to improve performance and security. The existing network was analyzed, and a new topology was designed. Implementation included the installation of new switches, routers, and firewalls. VLANs were configured for better network segmentation. The project resulted in a 40% increase in network speed and a significant reduction in security vulnerabilities.
Server Virtualization Project
A large-scale server virtualization project was executed using VMware vSphere. Physical servers were migrated to a virtual environment, reducing hardware costs by 60%. High availability and load balancing were configured to ensure optimal performance. The project also included the implementation of a disaster recovery plan using vSphere Replication.
Cloud Migration Strategy
A comprehensive cloud migration strategy was developed and implemented for a mid-sized company. The project involved assessing current on-premises infrastructure, selecting appropriate cloud services (AWS and Azure), and planning the migration of applications and data. The migration resulted in improved scalability, 30% cost savings, and enhanced disaster recovery capabilities.
Identity and Access Management (IAM) System Implementation
An enterprise-wide Identity and Access Management (IAM) system was implemented to enhance security and streamline user access across multiple applications and systems. The project included the deployment of single sign-on (SSO) capabilities, multi-factor authentication (MFA), and role-based access control (RBAC). User provisioning and de-provisioning processes were automated, reducing administrative overhead by 70% and significantly improving overall security posture.
Automated Patch Management Solution
An automated patch management solution was implemented using Microsoft SCCM (System Center Configuration Manager). The system was configured to automatically download, test, and deploy patches to all company devices. A reporting system was created to track patch compliance. This solution reduced system vulnerabilities by 75% and saved approximately 20 hours of manual work per week.
VoIP Telephony System Implementation
A VoIP telephony system was implemented across multiple office locations. The project included the installation of IP phones, configuration of a call manager, and integration with the existing network infrastructure. Features such as voicemail-to-email and mobile extensions were set up. The new system resulted in a 40% reduction in telephony costs and improved inter-office communication.
Cybersecurity Enhancement Initiative
A comprehensive cybersecurity enhancement initiative was undertaken. This included the implementation of a next-generation firewall, an intrusion detection and prevention system (IDS/IPS), and endpoint protection software. Security policies were updated, and regular vulnerability assessments were scheduled. Employee cybersecurity training was also conducted. These measures led to a 70% reduction in security incidents.
Business Intelligence Dashboard
A Business Intelligence dashboard was developed using Power BI. The dashboard integrated data from various sources including sales, finance, and operations databases. Custom visualizations and KPIs were created to provide actionable insights to management. The implementation of this dashboard led to more data-driven decision making and improved overall business performance.
Disaster Recovery and Business Continuity Plan
A comprehensive Disaster Recovery and Business Continuity Plan was developed and implemented. This included setting up off-site data replication, configuring failover systems, and establishing emergency communication protocols. Regular drills were scheduled to test the effectiveness of the plan. This initiative ensured business operations could continue with minimal disruption in case of a disaster.
Mobile Device Management Solution
A Mobile Device Management (MDM) solution was implemented to manage and secure a fleet of company-owned mobile devices. The system was configured to enforce security policies, remotely wipe lost devices, and distribute approved applications. This solution improved mobile device security and reduced the time spent on device management by 50%.
