Hi, I'm Sharan

SRE | DevOps | Cloud Engineer

I specialize in building self-healing, scalable infrastructure and making complex distributed systems reliable. Currently focusing on Kubernetes-native automation and high-availability database architectures.

Tech Stack & Expertise

  • Cloud & Infrastructure: AWS (EKS, EC2, S3), Oracle Cloud Infrastructure (OCI).
  • Orchestration: Kubernetes (StatefulSets, Operators, Service Mesh).
  • Infrastructure as Code: Terraform, Ansible.
  • CI/CD & Automation: Python, Jenkins, GitHub Actions, ArgoCD,
  • Databases: PostgreSQL (High Availability, Streaming Replication, CNPG Operator), MySQL Galera
  • Monitoring: Prometheus, Grafana (Service Reliability & Alerting), Zabbix.

What I'm Working On

  • HA-Database-on-K8s: Implementing 3-node PostgreSQL clusters with CloudNativePG, focusing on automated failover, leader election, and horizontal read-scaling.
  • Chaos Engineering: Experimenting with system resilience by simulating node failures and verifying recovery point objectives (RPO).
  • Python for SRE: Building automation scripts for infrastructure health checks and log analysis.
  • AI-augmented workflows: Using LLMs locally (Ollama) and automation pipelines (N8N) to speed up incident triage, runbook generation, and infra documentation - keeping the boring parts automated.

Fact Sheet

  • Experience: About 4 years in the Cloud/SRE and Private Cloud space.
  • Learning: Currently mastering Distributed Systems at scale, Reliability engineering and Operations
  • Fun Fact: Aspiring film analyst and Christopher Nolan fan.
