Hi, I'm
Designing secure, scalable and highly available enterprise infrastructure — across Windows, Linux, VMware, AWS and everything in between.
Infrastructure is a craft. I've been sharpening it for 12+ years.
I'm a Senior Infrastructure & Systems Administrator and Infrastructure Engineer based in Pune, with 12 years+ of hands-on experience running mission-critical environments — on-prem, virtualized and cloud-native.
I previously led infrastructure at Chetas Control Systems and am the founder of Prime Fixel, a boutique consultancy delivering managed IT and digital services to growing enterprises.
Deliver uptime, security and clarity to every organization I serve.
