Hi there! Managing complex cloud and on-prem environments while keeping junior engineers guided can be challenging, especially in a growing MSSP. I understand the need for reliable system architecture, automation, and seamless escalation processes. I have hands-on experience as a Senior / L3 Systems Engineer in MSP environments, managing Azure and Microsoft 365 setups, designing Proxmox + Ceph clusters, and automating provisioning and reporting with PowerShell and Python. I’ve also handled AD, DNS, DHCP, IIS, and RMM workflows, ensuring smooth operations across multiple clients. My approach will be to first audit your current systems, optimize Proxmox/Ceph performance, strengthen Azure & M365 environments, and implement automation scripts that reduce repetitive tasks while mentoring your L1/L2 engineers. This ensures reliability, performance, and security without gaps. Check our work https://www.freelancer.com/u/ayesha86664 Could you share the size of your current Proxmox/Ceph clusters and number of tenants supported? Let me know if you’re interested & we can discuss it. Best Regards Ayesha

Hello, I am a Senior Systems Engineer with strong experience supporting MSP/MSSP environments, leading escalation teams, and delivering secure, reliable infrastructure across cloud and on-prem systems. I have hands-on expertise in Microsoft 365 & Azure administration, including tenant governance, migrations, identity/security hardening, and automation-driven operations. I have worked extensively with Windows Server, Active Directory, DNS/DHCP, IIS, and enterprise troubleshooting in production environments. On the virtualization side, I have solid experience designing and maintaining Proxmox clusters, including storage integration and performance optimization. I’m also familiar with Ceph architecture, deployment, monitoring, and resolving cluster/storage bottlenecks. Automation is a key strength: I develop PowerShell and Python solutions for provisioning, patching, reporting, monitoring, and improving operational efficiency in multi-client environments. I’m comfortable working with RMM/ticketing systems, structured incident/change processes, and mentoring Level I & II engineers to improve resolution time and workflows. I am looking for a long-term engagement where I can take ownership, strengthen infrastructure, and help your team continuously improve performance and security. Let’s discuss how I can support your MSSP growth. Best regards, Umar

@mayankinnovative

Hi, As per my understanding: You are a growing MSSP seeking a Level 3 Senior Systems Engineer to architect and support complex Proxmox/Ceph virtualization, Azure/MS365 environments, Windows infrastructure, and automation workflows. The role includes escalation leadership for L1/L2 engineers, structured incident management, and long-term infrastructure optimization across multi-tenant environments. Implementation approach: I would approach this as both architect and technical lead. First, assess current Proxmox clusters (HA config, Ceph storage design, replication, performance tuning) and validate resilience. In parallel, review Azure and M365 governance, RBAC, Conditional Access, and migration practices. I would standardize automation using PowerShell (provisioning, patching, reporting) and Python for cross-system orchestration. Clear runbooks and escalation paths will be created to uplift L1/L2 capability. Monitoring, RMM integration, and structured change management will ensure reliability and SLA compliance. Focus remains on performance, security hardening, and scalable multi-tenant design. A few quick questions: Approximate number of managed tenants? Current Proxmox cluster size and Ceph topology? Do you follow ITIL-based ticket workflows?

@waqaswebmaster

I can operate as your L3 escalation + technical lead across Azure/M365 and Proxmox/Ceph, and I’ll back it with real automation (PowerShell + Python) so your L1/L2 team stops firefighting and starts closing tickets cleanly. I’m used to MSP/MSSP realities: multi-tenant standards, change control, RCA, runbooks, and tightening security without breaking production. Answering your questions: I have 7+ years with Windows Server/AD/DNS/DHCP/IIS and M365/Azure in MSP-style environments, 3+ years hands-on with Proxmox (clusters, HA, storage/network design, upgrades/rollback), and working exposure to Citrix/XenApp/AVD operations and troubleshooting. Recent work: Proxmox HA clusters, storage layout + performance fixes, backup/restore strategy, monitoring/alerting, and Azure/M365 governance (Conditional Access, MFA, RBAC, Intune baselines) plus migrations and incident response playbooks. Proxmox/Ceph: cluster design (quorum, network separation, MTU, bonding/VLANs), troubleshooting (IO latency, OSD health, PGs, recovery impact), and performance tuning (pool profiles, replication, compression, caching considerations) with clean maintenance windows. Certs: Azure fundamentals + Microsoft 365 administration track (happy to share exact IDs/screenshots in chat). If you want, I’ll start with a quick environment audit, define standards (gold images, naming, RBAC, patch rings), and implement automation + runbooks so L1/L2 can resolve more without escalations. Best regards, Waqas
