Participated in designing and developing Golang based monitoring tool for gathering various metrics like virtual machines, hardware info (dmidecode, WMI), Docker, networking stat, etc across Windows, Unix, Linux, and MacOSContributed into a few open-source project cloudradar tool is depending on.

I'm responsible for day-to-day management decisions in all technical areas of the team, including backend, devops, hardware, and embedded software developers. I implement long term and short term plans, establishing best practices, grow technical leaders.

I have shipped three high efficient battery-powered products for indoor air quality monitoring. These product solutions allow customers to keep track of various air quality parameters. In particular, a high level of CO2 decreases productivity, whereas high PM may lead to asthma or allergic. The algorithms on devices and in the cloud are giving forecasts to the customers in case values may reach danger values.

Designed and bootstrapped the cloud built on top of HA Kubernetes cluster with RabbitMQ, MQTT, Postgres, and various sets of Golang based applications able to handle 100k active devices.

On top of DASH-7 v1.2 specification designed RF stack for constrained devices with PHY based on LoRa and GFSK modulations. API of the stack easily allows implementing such application use-cases as OTA, NTP, device management (executing various commands), pushing calibration tables for sensors, etc.
