I handle every project personally, from the first concept through the prototype to operation. Short decision paths, direct communication, pragmatic solutions.
Own product: temperature monitoring for refrigerators and freezers in the food trade.
LoRaWANEmbedded sensingCloud & web app
Wireless sensors monitor refrigerators and freezers around the clock and alert via push, SMS and email before goods spoil. HACCP temperature reports for food-safety inspections are generated automatically. Sensors, LoRaWAN radio network, backend, web app and operations: the complete system from a single source.

Own project: a free, interactive pinout reference for the whole ESP32 family.
React & TypeScriptEspressif KiCad dataOpen source
Pick the wrong pin on an ESP32 and the device fails to boot, or crashes as soon as Wi-Fi starts. esp32pin.com shows every pin of more than 20 modules and dev boards with its real-world constraints: strapping pins, flash bus, ADC/Wi-Fi conflicts. The pin data comes straight from Espressif's official KiCad libraries; schematic and module views, a pin-mapping builder and PNG/PDF export included.
