Ishaq Tesleem

I’m a senior network engineer and IT administration lead with over 5 years of progressive success across IT administration, system support, network management, infrastructure maintenance, and cloud operations. I focus on keeping business systems reliable, secure, and always available—supported by strong troubleshooting, analytical, and communication skills.

At Leem-Tech Solutions LTD (2024 to present), I manage and maintain IT infrastructure, network systems, and wireless environments, achieving 99.9% network uptime for 100+ end-users. I oversee Windows and Linux server installations, upgrades, patching, and documentation, while implementing and monitoring security protocols like firewall rule optimization, IPS/IDS, VPN hardening, endpoint security, and periodic vulnerability assessments—delivering zero data breach incidents since implementation.

I also strengthen resilience through cloud services and backups using AWS infrastructure, automated encrypted snapshot scheduling, and backup and disaster recovery readiness—reducing unplanned data loss risk by 90%. Previously, as an IT Administration and DevOps Engineer at CapitalSage Holdings, I maintained 99.5% availability across 5+ server environments, improved monitoring to resolve 30+ recurring issues before user impact, and contributed to a scalable VoIP/cloud PBX solution that reduced telephony costs by 80%.
