    I specialize in infrastructure using terraform on aws and proxmox as well as kubernetes via flux in IaS environments. I have 21 years of general linux experience with apache, php, bash, python and various other scripting/programming languages. I have 7 years of expert level experience using memcache/redis and nginx application accelerator proxies based on Redhat and Ubuntu with php-fpm, apache, nodejs, java, .net and other application servers. These include zend, wordpress, drupal and several other web software suites. In one of my previous projects I was been able to allow for up to 40,000 simultaneous user sessions across twenty apache application servers utilizing nginx reverse proxies, behind several F5 load balancers. Initial hardware was able to accommodate up to 4,000 users. Since the application was not stateless nor was it designed for data segregation between private/public data the nginx rulesets were very complex requiring rewrites, header injections/strips and even body regex find/replaces. I also have expert level experience with large scale wordpress clusters from the file service and db aspects. I have experience with appdynamics, nagios and large scale ELK logging. I have experience with AWS, especially linux EC2 containers, elastic beanstalk and cloudformation. I am highly skilled in troubleshooting complex multi-tier interaction issues using system logs, stack traces and wireshark packet traces.

    I am closely working in software development industries since 2012 and it's about 8 and a half years since then. As a software developer, I am not a Language-specific developer but I can develop in any language. Of course, I have been working for the last couple of years as a Java developer. I am an expert in Elastic Search and it's all components and I always make sure the best uses of the precious searching solution in case of very high volume of data. I do prefer Java for writing large-scale applications and others in case of small apps. Usually, I use Spring Boot for developing RESTApi and EJB for writing SOAP Services. I am also interested to learn new technologies every day. As we all know Apache Kafka is one of the best messaging services is being used now a day and I always recommend my clients to use this powerful tool in case of enabling their application robust and flowless. Here is a list of technologies I have been working with. 01. Java 02. JPA 03. Hibernate 04. EclipseLink 05. ElasticSearch 06. Logstash 07. Kibana 08. Filebit 09. Spring Boot 10. Spring MVC 11. LDAP 12. Quartz 13. RMI 14. Apache Kafka 15. Apache Lucines 16. Object Storage 17. GoLang 18. Python 19. BERT 20. PostgreSQL 21. MySQL 22. MSSQL 23. Oracle 24. MongoDB 25. Weblogic 26. Wildfly 27.

Various skills: System administration: AWS, VPSes (Linode and DO are my preferred providers), dedicated servers (Hetzner, Softlayer/IBM), everything in between. I've done it all from hardware selection, racking, configuring/deploying, and maintaining. AWS Certified Cloud Practitioner - EC2, RDS, S3, IAM, SES, VPCs, and more - using console, API and CLI.
