Jagdish K.

I’m a hands-on Senior Software & DevOps Engineer with 13+ years of experience building, automating, securing, and supporting production systems. My core expertise is Java/Spring Boot, Microservices, AWS, Kubernetes, Terraform, CI/CD, Elasticsearch/OpenSearch, and Observability. I have worked on large-scale production environments where reliability, performance, security, and automation are critical. What I can help you with 1) Java / Spring Boot / Microservices development and modernization 2) AWS Cloud infrastructure, automation, security and operations 3) Kubernetes / Docker / EKS deployment and troubleshooting 4) Terraform / IaC for repeatable infrastructure 5) CI/CD using Jenkins, GitHub and automation 6) Elasticsearch / OpenSearch cluster setup, security, optimization and migration 7) ELK Stack – Elasticsearch, Logstash, Kibana, Beats 8) Observability – Grafana, Prometheus, OpenTelemetry, AppDynamics 9) Kafka and event-driven architectures * Production troubleshooting, performance optimization and reliability improvements I have strong hands-on experience with **large Elasticsearch environments**, including cluster design, security, scaling, monitoring, data ingestion, performance tuning, migration and disaster-recovery planning. I follow a practical engineering approach: Understand → Design → Implement → Automate → Secure → Monitor → Document I don't just provide recommendations. I prefer to work hands-on, implement the solution, troubleshoot issues, and leave behind documentation that your team can maintain. I have worked across the complete SDLC — requirement analysis, architecture/design, development, testing, deployment, production support and continuous improvement — using Agile and other delivery methodologies. My goal is simple: solve the problem properly, keep the solution maintainable, and deliver something that works reliably in production. If you have a challenging Java, Cloud, DevOps, Elasticsearch/OpenSearch or Observability problem, I’d be happy to discuss it.
