    Offload the mental stress of sorting out the nitty gritty details of the ELK stack and let me help create your data system for you. Clients often refer to me as their “cheat code” because a brief call with me can replace hours of frustrating trial & error and research. I have a simple goal: 1) To fully understand your needs, 2) Eliminate any stress or confusion, and 3) Deliver precisely what you’re looking for—taking care of all the details for you. I know how frustrating it can be to hire freelancers who complicate things further, communicate poorly, surprise you with unexpected costs, and require so much oversight that it feels easier to handle the work yourself. You don’t need to worry about that with me. Types of work I’ve done: Search Engine Development: Built and optimized high-performance search engines with a focus on user experience, achieving sub-500ms response times. A good search engine prioritizes user experience above all. The user needs to 1) get what they want (relevance), and 2) as fast as you can give it to them <500ms (latency), it's that simple. Full ELK Stack Implementations: Designed and deployed ELK stacks for diverse industries, including healthcare and renewable energy, handling everything from parsing error logs to integrating with third-party tools like Jira and Twitter. Custom Dashboard Creation: Developed visually appealing and functional dashboards for data visualization, enhancing team productivity and decision-making. Automation and Optimization: Automated cluster installations and optimized Logstash/filebeat/ingest pipelines configurations for efficient data processing and error handling. I will 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, alerting, siem, watcher, docker, AWS, OpenSearch Filebeat, metricbeat, packetbeat, Vega, RAG, LLM, AI augmented search, index templates,

I know how to install/configure/code: Web: apache, nginx, haproxy. Can recompile if needed, can install and compile modules. DB: Mysql (proficient), SQL Server (proficient), PostgreSQL (moderate). Programming Languages: Perl, Bash, PowerShell, JavaScript, Python. Monitoring Systems: Nagios (and derivatives), munin, monit. DNS: any system. Email: sendmail, exim, postfix. Hosting Panels: cPanel, Directadmin, VestaCP, ISPconfig. Virtualization: Amazon AWS - expert. Any other - can do.

For another task I learned JavaScript in 8 hours (sufficient enough to make a great Google Apps Script automation). It took me 3 days (24 cumulated hours) to learn Python. So if there is a technology not listed here, I either know it but didn't list, to save space, or I can learn it very quickly.
