💡 The combined Stats/Top-Languages card and Trophy Wall were dropped — they depend on a shared free Vercel deployment (
github-readme-stats.vercel.app/github-profile-trophy.vercel.app) that's currently returning 402 (quota exceeded) for everyone, not just this profile. Everything above is served by streak-stats, the activity graph, and shields.io, all of which are live and working. Your full language/tool breakdown already lives in the Tech Stack section below, and your Achievements table covers what the trophy wall would have shown.

Xmplar Management Solutions Pvt. Ltd. — Junior DevOps Engineer 📍 Madurai, Tamil Nadu, India | 🗓️ June 2025 – Present
Spring BootJava 17JenkinsAnsibleDockerKubernetesTerraformAWSAzurePostgreSQL
- Designed and shipped production-grade Spring Boot microservices & REST APIs for ERP modules (auth, inventory, scheduled jobs, reporting) and a Java ETL pipeline syncing MSSQL → PostgreSQL with skip-duplicate and aggregation logic.
- Performed JVM heap tuning (XMS/XMX) across 6 production services, cutting memory utilization by 30% and eliminating recurring CPU-spike incidents.
- Managed 8 major production releases across 15+ application instances via Jenkins/Ansible CI/CD, and architected a three-layer Disaster Recovery strategy (app, instance, cross-region) across AWS & Azure with automated AMI backups.
- Built and owned an observability & security stack (Grafana, Wazuh SIEM, Uptime Kuma, GoAccess) monitoring 20+ instances, administered HA PostgreSQL (streaming replication, WAL, PITR), and provided 24/7 incident response & RCA.
