• Built Kubernetes Operators (Kubebuilder/Golang) for network policies, monitoring, PaaS capabilities.
• Bootstrapped isolated & air‑gapped clusters via Kubespray, Rancher, RKE2.
• Security: OPA Gatekeeper policies, zero‑trust networking, legacy agent compatibility, middleware integration.
• Technical Lead for 11‑member Platform Team (architecture, planning, OKRs) within an org of ~80 DevOps engineers/SREs.

• Maintained DNS, DDoS mitigation firewalls, CDN edge, Anycast (BGP) + Layer 4 LB (Katran).
• Managed 45 bare‑metal edge servers nationally & globally.
• Developed Kubernetes Operators; automated server operations via Ansible (roles/collections).
• Delivered end‑to‑end provisioning automation (5× speed improvement) with Molecule + Python tests.
• Troubleshot Anycast issues daily for a 300 Gbps network; collaborated with customers for optimization.
• Implemented Prometheus + Alertmanager rules; introduced unit tests for ~30% of alert logic.
• Exposure to Google Cloud (GKE) and Proxmox virtualization.

• Containerized microservices (Docker / Compose); standardized unit, integration, and load testing.
• Automated >⅔ of tests and integrated into CI/CD (including load tests).
• Guided AI service adoption of DevOps practices: defined SLOs, tracked SLIs, communicated design rationale.
• Observability rollout (Prometheus, VictoriaMetrics, Sentry, Grafana alerting).
• Built PaaS API Gateway (authn/z, throttling, billing) for a portfolio of ~40 AI services.

• Produced HLD/LLD designs for diverse startup requirements.
• Back‑end (Golang/Python): implemented ML algorithms, handled high‑load workloads (up to 1,000 RPS / 100,000 TPS events).
• Django development; contributed to web security reviews & fundamental penetration testing.
