About this Gig

Your cluster is yellow, shards will not assign, queries crawl, or you need Elasticsearch built right the first time. I ran a 426-node Elasticsearch cluster with Kibana and Logstash in AWS for a U.S. government cyber operations customer. Yours is a quiet afternoon.


What I do:

Fix: red or yellow health, unassigned shards, node will not join, heap pressure, slow queries, disk watermark lockouts, failed upgrades.

Build: single node to multi-node on RHEL, Ubuntu, Docker, or Kubernetes. Elasticsearch or OpenSearch.

Tune: shard sizing, ILM, mappings, refresh and merge, heap and GC, hot-warm tiers.

Secure: TLS, users and roles, API keys, Kibana spaces.

Ingest: Logstash, Filebeat, Metricbeat, ingest pipelines.

Protect: snapshots, restore tests, monitoring and alerts.

Document: a runbook your team can run without me.


Platforms: Elasticsearch 7 and 8, OpenSearch, Elastic Cloud, AWS OpenSearch, self-hosted on any Linux.


How it works: send SSH or cluster API access, tell me what is wrong or what you need, and I start the same day. Every order ends with a plain-English summary.
