# Shailendra Dharmistan > Principal Architect | Builder | Zero Trust & Multi-Cloud Security | Built $100M ARR platform | Kubernetes • Rust • Go • mTLS/PKI Location: San Jose, California, United States Profile: https://flows.cv/shailendradharmistan I build and scale zero-trust, multi-cloud security platforms. As a day-one engineer turned lead architect, I helped take a cloud-native workload egress product from concept to $100M ARR, serving 500+ enterprises and 1M+ workloads across AWS, Azure, GCP, and Sovereign Clouds. I focus on SSE/SASE, identity, high-performance data planes, and reliability, measured by faster multi-cloud launches (12->3 months), P0 incidents -38% YoY, policy P95 ≤ 60s, and 99.9%+ fleet uptime. Recently: formal design authority over identity, autoscaling, and policy enforcement; provider-neutral architectures with Crossplane/Terraform; mTLS/PKI patterns fit for regulated environments (FedRAMP High / DoD IL5). Now advising early-stage teams shipping zero-trust data planes and multi-cloud control planes. ## Work Experience ### Principal Software Engineer @ Zscaler Jan 2019 – Present | San Jose, CA Product: Zscaler Cloud Connector—zero-trust workload egress via ZIA/ZPA; modern VPN/firewall alternative. Scope: technical owner for identity, autoscaling, policy across AWS/Azure/GCP/OCI; formal design authority. Impact: grew from concept to $100M ARR; 500+ enterprises, 1M+ workloads, 10K+ deployments. Multi-cloud acceleration: provider-neutral services & CSP adapters (Crossplane/Terraform) → 12→3 mo launches. Reliability/SDLC: SLO/error-budget, progressive delivery, AIOps; P0 −38% YoY, P95 ≤ 60s (P99 ≤ 180s). Capacity/uptime: 16× per-cluster sessions, 3× per-VM; ~2-min autoscaling; 99.9%+ uptime. Hands-on: Go services (policy engine, identity broker, autoscaler), K8s operators, Crossplane/Terraform modules. Customer results: MTTR −46%; direct engagement with 50+ F500 accounts; expansion revenue $10M+. ### Senior Technical Leader @ Cisco Jan 2015 – Jan 2019 | San Francisco Bay Area Lead Engineer/Open Source Software Developer on the Cisco ACI platform focusing on bringing application policy abstraction to opensource Compute and Networking stacks. • Designed and developed infrastructure software to deploy Cisco ACI Container Networking Interface (CNI) plugins on Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform. • Designed and developed infrastructure features on open source networking stacks • Designed and developed OpFlex Agent Features.
