Welcome to my blog. I am a hobbyist turned embedded system design consultant, deeply in love with electronics for more than two decades. 

As a consultant I help hardware companies build reliable and successful embedded products.

Contact me for your custom embedded design needs.

The platforms I work on are STM32, nRF52/53 Wireless SoC, Apollo 3 MCU, ESP8266, ESP32, Embedded Linux System-on-Modules, etc.

On this blog, I share technical articles which are useful for engineers who are starting their journey in embedded as well as practical embedded design tips which are useful for experienced engineers.

I also regularly write about new embedded boards and ICs which are worth exploring.

Recently, I have started my YouTube channel where I review various test instruments (power supplies, dc load, etc.) and create teardown videos.
