Vibe Smart Homes is a retrofit home automation solution designed for the Indian household. It is a suite of smart devices including smart switches, curtain controllers, LED dimmers, gas sensors, IR emitters, etc.

As the principal software architect, I was in charge of the team that built the entire software solution from firmware to mobile apps to cloud. I developed most of the firmware and the Linux-based smart gateway software as well as provided the team with high-level design for the mobile apps and the cloud including the DB design.

MediaRoom was Microsoft's end-to-end IPTV solution and the first live product I ever worked on (the business was later bought by Ericsson). I was part of the dynamic team that was responsible for the managed code of the DVR component on the set-top box (STB).

As a fresh grad, I was fortunate to work with some of the best minds in the industry. All of the managed code was written in C# using the .NET Compact Framework. Until I joined the team, I had never seen any C# code but, with the help of the team, I was writing production code in less than a couple of weeks. And in less than a year's time, I was independently implementing as well as managing the lifecycle of new features for the DVR!

At Microsoft, I learned how to apply my raw programming skills to write production quality code using best practices, TDD, Scrum, and more.

The "Biker Radio" (internal code-name as the product is yet to be released) is a battery operated wireless radio for group communication. It has the following peripherals:
1. TI audio codec for real-time audio capture and playback
2. BLE module for communication with mobile apps
3. SemTech's LoRAWAN-based low-power radio module for wireless communication
4. STM32 based low-power MCU for integrating all of the above peripherals

I designed and developed most of the firmware including the code for the SPI, I2C, I2S and UART interfaces using the STM Cube and LL libraries.

I also developed the Xamarin Forms-based mobile application that allows the user of the hardware to create groups, add friends, and view the location of all members of the group even without a cellular network.
