Work Experience
DevOps Engineer
Lumber
- Solely owned end-to-end deployment of 30+ production-grade services across 5 Kubernetes clusters (Python, Java, and Node.js stacks) — Dockerization, Helm charts, manifests, CI/CD wiring, secrets, and observability.
- Drove org-wide GitOps adoption by migrating all services to ArgoCD — automated sync, self-heal, drift detection, and one-click rollbacks with full deployment audit history.
- Migrated secrets management from Ansible playbooks to a HashiCorp Vault cluster with the External Secrets Operator (ESO), centralizing secret storage, access control, and rotation across all environments.
- Cut ~$4,800/month in AWS spend via Athena partitioning (99% cost cut, $1,700 to $9/month), single-AZ non-prod RDS/EKS, and automated off-hours shutdowns; added org-wide tagging and billing alerts.
- Architected end-to-end monitoring with kube-prometheus-stack (Prometheus, Grafana, Loki, Alertmanager); alerting spans AWS services (RDS, EC2) down to pod crashes and CPU spikes.
- Instrumented all services with OpenTelemetry distributed tracing and structured JSON logging; integrated Coralogix for unified logs/metrics/traces and enabled its CSPM module, surfacing 60+ security findings.
- Migrated infrastructure, including Jenkins build machines, from AMD64 to ARM64 (AWS Graviton) with multi-platform Docker builds for all 30+ services, improving performance and reducing compute costs.
- Architected a fully isolated AWS environment (dedicated VPC, EKS, subnets, IAM roles, Kubernetes RBAC) to meet a client’s strict network segregation requirements.
- Engineered CI/CD workflows for Python, Java, and Node.js apps running unit, integration, and Playwright tests at PR time; optimized Jenkins pipelines with parallel stages, accelerating builds by 27%.
- Introduced Trivy image scanning across all build pipelines (shift-left DevSecOps), remediating 25+ CVEs to strengthen supply-chain security.
- Resolved recurring OutOfMemory (OOM) crashes in production by provisioning Kubernetes PVCs to capture JVM heap dumps on crash, enabling root-cause analysis and permanent fixes.
- Provisioned Windows-based sandbox environments for 5+ integration partners (Acumatica, Sage 100, Sage 300, EiDynamics), enabling end-to-end partner testing before production.
- Led incident response for critical production issues — storage shortages blocking deployments, bastion host crashes, zero-downtime node group migrations, subnet/IP exhaustion — reducing Mean Time To Resolution (MTTR).
Software Development Engineer Intern
Lumber
- Optimized API performance by identifying and eliminating bottlenecks in functions and database calls using YourKit profiler.
- Slashed data storage footprint by 13% by eliminating duplicate entries in Postgres audit tables, reducing infrastructure cost and query load.
- Drove unit test coverage >93% across a multi-module Spring Boot application, reducing regression issues.
