HW & SW Engineer
I focus on IT infrastructure, monitoring, automation, embedded systems and IoT integrations. I enjoy connecting hardware, software and real-world operations in a way that makes the final solution usable, measurable and maintainable over time.
My practical experience ranges from servers, virtualization and operational dashboards to sensors, data flows, industrial protocols, electronics and prototyping.
I help companies design, integrate and deploy IT infrastructure, monitoring, IoT and other technical solutions. I can contribute to a specific project, a proof of concept or an ongoing collaboration, from initial analysis to a working deployment.
Linux and Windows servers, virtualization, network services, web servers, reverse proxy, backups and operational monitoring. Hands-on experience mainly with Proxmox VE, VMware ESXi, Docker, GitLab, Nginx / Apache, Zabbix and Grafana.
Design and integration of IoT and embedded solutions from sensors and communication networks to data processing and visualization. Platforms and technologies include ESP32, Particle, Arduino / ATtiny / ATMega, Raspberry Pi, I/O modules, LoRaWAN, NB-IoT, LTE / 5G, BLE and MQTT.
Programming, scripting and system integration focused on connecting technologies in real operation. Primarily C, C++, Bash, plus SQL, HTML/CSS, basic Python and JavaScript, Node-RED, REST APIs, WebSockets, MQTT, Modbus and CAN.
Practical technical overlap into design, prototyping and concept validation. Experience with Autodesk Fusion, 2D/3D modeling, 3D printing, manual PCB assembly and soldering of small electronic components (under magnification / microscope and using hot-air rework), various sensors and building functional prototypes.
Development and integration of electronic systems for a micro data center, including sensors, operational telemetry, control of technical subsystems, and hands-on assembly, soldering and bring-up of various PCB designs.
Design and development of centralized monitoring across multiple sites. Automated device onboarding, standardized configurations, custom scripts and Zabbix extensions, operational status evaluation and preparation for future alerting workflows.
Connecting distributed technical equipment, sensors and energy systems using Modbus and MQTT; processing data flows with Node-RED, and storing and visualizing telemetry using InfluxDB and Grafana.
Besides technical projects, I occasionally work as a DJ, mainly for weddings, celebrations and smaller events. I build the music around the people, the atmosphere and the flow of the event - from a calmer beginning to the evening dance part.
My goal is for the music to feel natural, keep a good mood and help create an evening people will enjoy remembering.
