    Need to organize, understand and visualize your large amounts of streaming data on clean, easy-to-use dashboards for one or more users? I'm an Elasticsearch, Logstash and Kibana expert here to solve your problem. Instead of having your own team take 2 weeks to solve your ELK issues, hire me for a few hours to save time and money. My focus and expertise with the ELK stack and I've worked with a variety of projects implementing it for small one person teams, and for large enterprises. If you want a competent engineer that will first understand YOUR needs and second create a solution that directly addresses those needs, I'm the engineer for you. I ask a lot of questions to make sure I understand what your needs are so you don't need to waste time looking at solutions that aren't what you need. I've always spent time explaining things to clients in a clear way so that you can fully understand what I'm doing so that you can take over and solve problems if you need to. I work efficiently, learn fast and create things with integrity. Are you a social enterprise with a noble cause? Send me a message, I'd like to talk. I offer discounted rates for particular projects. Some bullet points on a few implementations I've worked on: Fully architected, designed, and implemented the ELK stack many times, organizing everything from healthcare data to solar panel grids to difficult-to-parse error logs Created relevant and beautiful custom dashboards that teams use to visualize large data sets, and monitor the health of apps/websites. I've also developed custom plugins that interact and manipulate the data in meaningful ways (3rd party integration with Jira, Twitter, etc..), and can install any custom Kibana plugins available on Github (and Vega). Worked with X-pack (watcher / alerting, security / shield, machine learning) and can make your system do what you want it to. If you're interested with one of the free alternatives, I can make those work for you too (open source multi-tenancy, open source security, etc...) Managed and automated the cluster installation and node health on multiple machines. Created and optimized Logstash config files with many different inputs, filters and outputs. For critical errors, email escalation. I've played with it all. Filebeat, metricbeat, packetbeat and other beats are all within my scope of work. I can create a search engine that does what you want it to. I can explain things in layman's terms and not fill an explanation of how something works with technical jargon. I will be clear with my expectations and love to explain how things work so you can do it yourself. Let's work on your project together so that you can get what you want out of your data. Additional Competencies: API integration with ELK: Facebook, Google Analytics, Twitter, etc... Automation of ELK: Bash and Ansible External Database Syncing with ELK: SQL, MongoDB Misc: Readonly Rest, Own_home, Searchguard, Graphite
