The product in the design and development of which I participated was awarded by the European Commission in the BOWI competition as one of the best Ukrainian products in the Industry 4.0 category. And the company received a European grant for its development.
I'm a skilled IT and Industrial Automation engineer with development and administration skills and with over 12 years of experience in Linux and Windows environments. I have experience in building internal IT infrastructure and develop applications for Industrial Automation. Outstanding ability to adapt to a changing IT environment, quickly learn new concepts and apply knowledge effectively.

As system administrator I worked with various systems, beginning from bare metal servers up to cloud infrastructures. I have experience with 3 node Proxmox cluster, and FreeNAS based ZFS storage (with zfs stream replication to remote system). I am maintaining IT infrastructure for company with ~50 employee (head office) and 1 remote location (VPN bridge to head office). AD, DHCP, software installation automation, integrating external systems via LDAP: gitlab, Rocket Chat, mailserver, odoo, etc.
I also operate with video surveillance systems, access systems.

As software developer I have experience with supporting old legacy industrial system (Originally developed using Visual Basic 6), modernize it with C/C++ modules. Also I participated in the development of the control system of seventy tons bunker scales. I develop HMI using C++ and Qt Framework.

I designed and was a backend developer of a complex cloud system for monitoring and optimizing the work of industrial production.  That is based on the principles of Industry 4.0 and IIoT. (Java, Spring, PostgreSQL, influxdb, Grafana, MQTT, AMQP and etc.) On this project I also gained experience as a DevOps engineer: terafform, kubernetes and etc.

In previous projects, I have been custom building OpenWRT (and buildroot) Linux systems.  Created automatic installers (and ISO images) based on debian and ubuntu (also with live mode). For technical support, I built VPN networks and packaged client software for these images. Also I operate MeshCentral system ( Open Source self hosted system, similar to TeamViewer).
I would like to grow as a software developer in a product company, or extend my sysadmin skills as a DevOps engineer.
