Girish S
I design, automate, and operate the cloud and on‑prem systems that production software runs on - provisioning bare metal, wiring up CI/CD, and keeping everything observable and resilient at 99.99% uptime.
Tools I run things with
Everything from provisioning bare metal to shipping apps and watching the graphs - grouped by where it lives in the platform.
Where I've shipped
A timeline of roles, most recent first - from on-prem data centers to multi-cloud automation.
Operating and automating the compute, storage, and data-center infrastructure behind Five9's platform - working across enterprise storage and SAN fabrics (NetApp, HPE, Pure Storage, Cisco MDS), applying SRE practices to keep services reliable, and performing change requests (CRs) to roll out changes safely.
Built workflows and automated cloud infrastructure end to end, delivering scalable solutions across fast-paced product teams - spanning CI/CD, cloud architecture, and on-premise data-center operations.

// CI/CD & cloud architecture- Developed end-to-end CI/CD pipelines using Jenkins, GitLab CI, and Expo (EAS).
- Automated Android/iOS build workflows with secure service accounts and IAM-controlled access.
- Deployed and maintained Node.js / Next.js apps on Nginx across staging and production.
- Orchestrated master-slave database replication for high availability and read scalability.
- Handled DNS configuration, performance tuning, and host-level troubleshooting.
Bolt.sh - On-premise Data Center
// infrastructure, networking & security- Configured RAID levels, IP addressing, and subnetting for production servers.
- Implemented Palo Alto & Sophos firewalls with strict security policies and NAT.
- Deployed MAAS for automated bare-metal provisioning and ran an OpenStack on-prem cloud.
- Established real-time visibility with Zabbix (SNMP) - automated maps and alerting.
- Set up VPN solutions and AAA security services using RADIUS.
- Streamlined operations to achieve 99.99% uptime across on-prem and cloud.

Beyond the data center
The other processes always running in the background - the things that keep me sharp, creative, and recharged.
