Comprehensive Desktop & Network Support

@bharatenterprize

Hello, I’m a working System Administrator with hands-on experience managing mixed Windows and Ubuntu environments in production setups. My day-to-day work includes workstation troubleshooting, OS re-imaging, disk replacements, patch management, and backup verification with minimal user downtime. On the Ubuntu side, I regularly handle fresh server installations, user and permission management, SSH hardening, unattended security updates, firewall configuration (UFW/iptables), and CLI-based administration. I’m comfortable stabilizing systems quickly when reinstalling is the fastest and cleanest fix. I also manage networking and firewalls, including basic-to-clean baseline setups (NAT, standard rules, limited port exposure, credential hardening) on Cisco, Mikrotik, and TP-Link devices. I routinely troubleshoot LAN/WAN issues, configure VLANs, adjust routing, and back up switch/router configurations. I document every change clearly in ticketing systems and can work during GMT+0 to GMT+3 overlap for quick calls or screen sharing. Happy to start with focused support and grow into a longer engagement if needed. Above mention cost is per hour cost (flexible for long-term work).

I am writing to express my interest in this role and believe my hands-on systems and networking experience aligns well with your requirements. I have strong experience supporting mixed environments of Windows workstations and Ubuntu-based systems, where stability and quick resolution are critical. I am comfortable with real-world troubleshooting, including replacing failing laptop hardware, resolving driver and OS issues, performing clean OS re-installations, and ensuring systems remain fully patched and backed up with minimal user disruption. I have hands-on experience with Ubuntu server administration, including fresh installations, user and permission management, CLI-based administration, updates, and SSH hardening. I also have experience configuring hardware firewalls from a clean baseline, implementing standard security rules, NAT, restricted port exposure, and validating default credentials, with documented configurations. Networking is a core strength of mine, including tracing cabling issues, configuring VLANs on managed switches, troubleshooting LAN/WAN connectivity, and maintaining routing between branch offices. My background is primarily with Cisco networking equipment, along with experience supporting Mikrotik and TP-Link devices.

Hello, I work with mixed Windows and Linux environments where stability, fast troubleshooting, and clear documentation are essential. I am comfortable stepping into live environments and resolving issues efficiently without unnecessary disruption. For this project, I will support both desktop and server operations with a practical, hands-on approach. On the Ubuntu side, I will handle fresh server installations, user management, patching, SSH hardening, and routine CLI administration to keep systems secure and reliable. For end-user systems, I will troubleshoot hardware and software issues, replace or re-image systems when needed, resolve driver problems, and ensure systems remain patched and backed up with minimal downtime. I will also bring hardware firewalls to a clean baseline configuration, including basic rules, NAT, limited port exposure, and credential checks. Network issues across LAN and WAN will be diagnosed and resolved, including cabling checks, VLAN configuration on managed switches, and routing adjustments between branch offices. All work will be documented clearly in your ticket system so changes are traceable and easy to follow. My objective is to keep your daily operations stable, responsive, and easy to maintain. Best regards, Rifqi
