SecureGrow provides IT services and expertise to small businesses in Central Florida. Our goal is to help these businesses succeed in a competitive market. I have a strong record in documenting and managing Point of Sale (PoS) equipment, achieving seamless integration through configuring Meraki Cisco equipment, and supporting network cabling for optimal data transmission. Expertise also includes upgrading PoS systems and network equipment, conducting security audits, and implementing Web Application Firewalls to enhance IT security. Additionally, I have experience in developing websites using front-end and back-end technologies, including Linux server environments and increasing their visibility through strategic digital marketing. Have advanced skills in providing remote technical support using Quick Assist and TeamViewer, setting up Office 365 on company devices, and guiding users through enabling Microsoft Authenticator for enhanced security.

At Santander Consumer, I specialized in network security and firewall management. I created and managed firewall policies for POS systems and URL filtering, administered Cisco Firepower and Check Point firewalls, and developed VPN policies. I configured firewall rules, analyzed data traffic, and implemented RegEx filters. My role included monitoring connections, conducting risk analyses, and presenting impact assessments on Linux-based firewalls. I developed a Python program for firewall backups, automated user documentation for 5000+ records, and enhanced compliance using Splunk. Additionally, I managed network objects with the Check Point Management console and ticket management via ServiceNow.

At EIS Security, I excelled as a Security Analyst, leading penetration and vulnerability testing for customer websites hosted on Linux servers. I managed Linux and Unix environments, ensuring robust security through regular system performance tuning and automated resource monitoring. My role involved configuring VMWare ESXi for a WordPress-based knowledge base and conducting thorough code reviews in C++ and Python to identify buffer overflow vulnerabilities. Additionally, I maintained customer websites, assessed vulnerability concerns, and researched asset information and troubleshooting guides for Linux environments. Throughout my tenure, I developed strong customer relations and provided exceptional technical support and solutions.

At Hughes Frontline, I excelled as a Security Analyst by providing technical support for PoS devices and supporting Fortinet boxes, Verifone PoS, Hughes, and Cradlepoint modems. I diagnosed and remotely resolved Layer 1, 2, and 3 network issues and implemented ARP to display network devices on Linux systems. I reviewed and updated network diagrams in the ticketing system and reckoned vulnerability issues using firewall and modem log scripts. Role included accessing modem admin portals for log control, collaborating with the network engineering team, and developing RegEx scripts to change MAC addresses for device identification. Additionally, I enabled Linux subsystems for RegEx and shell scripting, automated network tasks, monitored system resource usage, and managed network devices using remote tools. Throughout, I provided first-level help desk support and completed onsite tech signoffs and ISP dispatch requests.

At SentryView Systems, I specialized in Linux environments, developing guides for implementing software updates and troubleshooting systems, applications, and network issues. Extracted data logs from malfunctioning units using Linux Arch and refactored C++, Python, shell script, and Wireshark code. Developed power solutions for monitoring units, managed user accounts and permissions, and created upgrade scripts using shell script, Perl, and C++. My role included configuring Active Directory, routers, and firewalls, patching security vulnerabilities, and scheduling backups of critical data directories. I also developed automation scripts that reduced manual system monitoring by 50%, maintained network and server solutions, and ensured data integrity with backup and restore scripts.
