"DevOps and SRE engineer with 3+ years building and operating Kubernetes platforms on AWS and Azure. Cut cloud spend ~50% (~$11K/month) at a fintech serving 22M+ requests/day, accelerated deployment cycles 50% via GitHub Actions and ArgoCD, and led a zero-downtime AWS-to-Azure multi-cloud migration."

DevOps Engineer 2

• ▹Drove a company-wide FinOps program cutting AWS spend ~50% ($22.5K → $11.3K/mo, ~$134K annualized) via Graviton migration, Karpenter spot pools, RDS snapshot cleanup, S3 lifecycle policies and NAT/networking consolidation — zero performance regressions.
• ▹Leading the full AWS-to-Azure exit of the ZET Partner OU — migrating 5 AWS accounts and 15+ Kubernetes workloads to AKS, Aurora MySQL → Azure Database for MySQL Flexible Server, S3 → Blob Storage, on Terraform-managed landing zones using Workload Identity for keyless access.
• ▹Architecting cross-region Disaster Recovery (ap-south-1 ↔ ap-south-2) for tier-1 services with Aurora Global Database and a Pilot Light active-passive topology — targeting RTO/RPO under 20 minutes with automated failover runbooks and quarterly game-day drills.
• ▹Built ephemeral preview environments (GitHub Actions + Helm namespace-per-PR on Karpenter spot NodePools) isolating per-PR tests for 17+ microservices serving 22M+ requests/day, while owning platform reliability at a sub-0.1% error rate.
• ▹Replaced managed ElastiCache Redis with self-hosted Valkey on EC2 Graviton across prod and staging, fronted by Route 53 private DNS — eliminating per-hour ElastiCache cost with zero application changes.
• ▹Deployed VictoriaLogs alongside OpenSearch via Fluent Bit rewrite_tag routing, cutting multi-GB log query latency and storage cost; migrated Nexus from x86 to ARM64 Graviton ($741/yr saved, no CI rebuilds).

DevOps Engineer

• ▹Migrated EKS production workloads (Java, Node.js, Python, Ruby) to ARM64 Graviton, contributing to a ~42% AWS cost reduction with no latency regression.
• ▹Optimized EKS performance — pod startup 45s → 18s, KEDA autoscaling on Prometheus RPS metrics across 15+ microservices, and ungraceful spot evictions cut 45% via Pod Disruption Budgets and chaos testing.
• ▹Led the AWS-to-Azure multi-cloud migration — AKS in segmented VNets, Azure Database for MySQL with read replicas, Application Gateway + WAF, and ACR/Key Vault/Service Bus/Storage behind private endpoints with zero public exposure.
• ▹Consolidated Grafana and New Relic into Datadog (infra, APM, logs, SLOs) — MTTR down 40% and 35% of false-positive alerts eliminated.
• ▹Enforced zero-trust with Twingate, JumpCloud SSO, IRSA, IMDSv2 and AWS WAF — zero audit findings and a 60% reduction in high-risk vulnerabilities.
• ▹Standardized multi-account governance (Control Tower, SCPs, GuardDuty, IAM Identity Center), built GitHub Actions CI/CD across staging/QA/prod, and stood up a Metabase + Databricks BI platform with automated ETL.

DevOps Tech Lead

• ▹Led DevOps transformation across dev, QA, pre-prod & production Kubernetes environments for streamlined deployments.
• ▹Designed AWS auto-scaling that scales instances on demand — optimizing cost while holding performance.
• ▹Implemented Terraform IaC for consistent, scalable multi-cloud infrastructure.
• ▹Automated CI/CD with Jenkins & ArgoCD — release cycles down 50% and deployment errors minimized.
• ▹Migrated self-hosted MongoDB to MongoDB Atlas, improving scalability and security posture.

DevOps Engineer & Full Stack Developer

• ▹Architected complete AWS EKS infrastructure with Terraform, reverse-engineering the existing setup via Terraformer while preserving legacy systems.
• ▹Orchestrated DigitalOcean→AWS migration with minimal downtime; added CloudWatch and Loki-Grafana monitoring.
• ▹Implemented HPA and Auto-Scaling Groups with zero-downtime rolling upgrades.
• ▹Built a VPN + firewall system that cut unauthorized access attempts by 95%, plus a Python cronjob-based DB backup service for disaster recovery.
• ▹Led migration from community GitLab to a self-hosted instance, streamlining repo management and collaboration.

Software Developer

• ▹Spearheaded a video conferencing web app integrated into the core product platform.
• ▹Built a versatile file-converter API that cut processing time 50% through optimized backend architecture.
• ▹Designed scalable back-end services in Flask & Node.js with seamless front-end integration, and ran POCs to improve UX and operational efficiency.

AWS Training Instructor

Ran a week-long AWS certification program at St. Francis Xavier — taking 20+ final-year B.Tech students from cloud fundamentals through hands-on labs and assessments, with the cohort achieving AWS Academy Cloud Foundations certification.
