Senior Associate (DevOps Engineer)
Lexplosion Solutions Pvt. Ltd.
- Architected the complete cloud platform on Amazon EKS, a new regulatory-compliance product handling UPSI — owning infrastructure, Kubernetes platform design, CI/CD, GitOps delivery, and observability.
- Implemented GitOps with Argo CD as the single source of truth for all deployments — authoring Kubernetes manifests for 7– 8 microservices with Kustomize overlays generating environment-specific objects from the base configuration.
- Deployed Karpenter for just-in-time, workload-aware node provisioning and autoscaling, improving cluster utilization and cost efficiency over static node groups.
- Built the in-cluster observability stack with Prometheus, Grafana, Grafana Alloy, and Loki, unifying metrics and log aggregation with per-service dashboards and alerting.
- Led end-to-end cloud infrastructure for Komrisk during its Java 7 monolith to Java 17 microservices migration — owning infrastructure, CI/CD, monitoring, alerting, logging, and backup across 1 multi-tenant and 5+ single-tenant production environments on AWS.
- Re-architected the Amazon ECS (EC2 launch type) deployment: decomposed a single task definition bundling 6 coupled services into per-microservice task definitions and ECS services with dedicated capacity providers, and containerized remaining legacy services running as bare EC2 processes — enabling independent scaling, eliminating cascading failures, and delivering zero-downtime rolling deployments across 100% of services.
- Built a hybrid per-microservice observability stack: Prometheus and Grafana for application metrics (Spring Boot Actuator) and log visibility, plus Amazon CloudWatch dashboards and alarms for ECS services, capacity providers, cost, and database servers — replacing coarse instance-level alerts with actionable service-level signals, establishing real-time SLI/SLO visibility and reducing mean time to resolution (MTTR) by 35%.
Associate (DevOps Engineer)
Lexplosion Solutions Pvt. Ltd.
- Spearheaded the Infrastructure as Code adoption with Terraform and Terragrunt, replacing manual provisioning with standardized, environment-specific, repeatable AWS infrastructure for every.
- Own day-to-day incident response and root cause analysis across entire production environment — triaging alerts, diagnosing failures via logs and metrics, and driving permanent remediation; this ongoing practice underpins the MTTR improvement and informs continuous reliability.
- Engineered end-to-end Jenkins CI/CD pipelines covering automated checkout, build, test, Trivy vulnerability scanning with published reports, and parallel deployment of independent microservices — replacing a manual, shell-script-driven release process and reducing deployment time by 70% (and failed-release recovery time by over 80%).
- Optimized service Dockerfiles with slim base images, multi-stage builds, layer caching — shrinking Spring Boot images from 900 MB to 200–350 MB (up to 75% reduction) and improving deployment speed and container security.
- Consolidated redundant per-tenant Amazon ECR repositories into service-specific repositories with a consistent tagging strategy, and centralized JAR/WAR artifacts in Nexus Repository backed by Amazon S3 — reducing registry sprawl and enabling reliable rollbacks.
Freelance Cloud / DevOps Engineer
XtraCoLabs
- Advised on AWS cloud architecture and cost-aware service selection for an early-stage product, and implemented static website hosting with S3, CloudFront, and Route 53 for globally distributed, zero-maintenance delivery.
- Contributed to MVP backend development using Django with authentication workflows and MySQL integration, supporting early-stage deployment and environment setup.
