Paresh Raval I keep critical infrastructure online, secure, and fast.
Systems Administrator and Cloud & Technology Consultant with 9+ years running mixed Windows / Unix / Linux fleets, SAP HANA landscapes, and virtualized estates — engineered for 99.9% uptime and built on automation, monitoring, and defense in depth.
+ Virtualization
I'm a systems administrator who treats reliability as a feature. Over the last nine years I've moved from desktop support into running production server estates — installing and tuning SAP HANA and SQL Server, migrating databases, and standing up cloud landscapes on Microsoft Azure.
My day-to-day spans hypervisors (Proxmox VE, VMware ESXi), firewall management (Fortinet, Dell SonicWALL), and observability with Prometheus and Grafana. I automate the repetitive, harden the exposed, and document the rest. As a Certified Ethical Hacker, I bring a security-first mindset to everything from patching to access control.
Based in Ahmedabad, Gujarat, India — available for infrastructure, cloud, and SAP B1 administration work.
