Skills

Embedded Systems

I have experience in Firmware-first embedded system design and MCU-centric hardware development (schematics, power design, layout, and bring-up)

I enjoy working close to the hardware, where performance, power, and reliability decisions are made at the system level.

Back-End Development

Beyond the device layer, I have additional experience on building backend systems that support IoT deployments. Handling device communication, telemetry ingestion, observability, and scalable cloud integration.

My aim is to extend the capabilities of edge devices through reliable data flow, remote management, and system visibility.

Who I am

Embedded Systems & IoT Specialist

I specialize in hardware–software system integration, with embedded systems as my core specialization, while also leveraging my back-end development experience to build applications that enhance and extend hardware functionality.
