Annim BanerjeeKolkata, India
Embedded Hardware Design Engineer

Worked In: Bangalore, New Delhi, Kolkata, China.
Work Experience: 7 Years.

I help Hardware and Software Startups and Established Tech Companies to bridge between hardware and software for their Products.

Embedded Engineer with 7 years of work experience in designing and developing PCB, Firmware development, and Linux Device Drivers for Custom Linux SBCs. Rapid prototyping to mass production projects which often has BLE, Wi-Fi, LTE, and LoRa based communication applications is the prime focus segment.

Over the years, as the understanding of the Internet of Things and technology around it got better, my ability to bridge between the hardware and software sky-rocketed. This helps me to pack hardware with major IoT protocols and software technologies which mostly runs on mobile or web platform.

From this Win32 GUI application, anybody can take this as reference for doing GDI+ graphics related activities, or as Win32 Dialog based application illustration. I tried to develop the LMST in my way which is not the optimised algorithm right now. I have used linked list to handle Vertex of Graph and also to handle Edges
