R&D Embedded System Engineer
Four Corners Technologies (4CT) Pvt. Ltd, India.Oct 2016 - Nov 2018 (2.1 years)
At 4CT, we developed end-to-end IoT smart solutions for retails, workspace, kiosks, and outdoor billboards. I was the hardware guy in this firm, where my role was to design-build-program the wireless embedded system of IoT devices, then connect its data stream to cloud services hosting our in-house analytics engines. Below is the list of projects that I contributed to, which are currently deployed on a large scale and one of the high revenue sources for the firm.
Workspace Occupancy Monitoring: We designed a wireless embedded system with Panasonic Grid Eye thermal sensor to monitor the workspace occupancy. This occupancy data was sent to our web app to generate client requirement-based meaningful insights such as rich visualization of building and workspace utilization, detailed occupancy patterns, extensive reporting of occupancy by the department and by function, etc.
Remote Hoardings Monitoring: We designed an IP66 grade Linux-based IoT camera with 4G connectivity and integrated multiple outdoor LDR sensors. 250 of our IoT cameras were installed across the city and rural areas to monitor the outdoor billboards to provide view clarity, material quality, installation quality, pillar quality, lighting quality, live stream, etc. when requested by the billboard owners or clients via our billboard management system.
Retail Sense 'Progressive business decisions with live data at your Fingertips'. We designed Retail Sense, which is a low-cost camera-based wireless footfall people counter. The raw footfall count was sent to our web app, where it was converted into meaningful information that revealed patterns and profitable insight which is used to make key decisions on ideal staffing levels with placement based on the hour, day, month, season, facility’s layout and operations, etc.
e-Health Kiosks: We designed an MCU-based embedded system using sensors to accurately measure the height (using MaxBotix ultrasonic sensor), weight (using load cells mapped to a 24 bit ADC), and heart rate (using Max30100 pulse oximetry sensor). This board computes the height (cms) weight (Kgs) and heart rate (BPM & SPO2) and sends it to the system of the digital signage kiosk via USB.
R&D Intern - IoT Sensor Applications

Then I integrated the sensor data into the cloud-level analytics suite designed by other team members.
After successful solution deployment, car drivers could get real-time information about unoccupied parking spots and find one much quicker. The benefits for our client include reduced labor-intensive fixed message signs, reduced traffic congestion and pollution as we reduced search time for free spots, set dynamic hourly rate pricing based on real-time changes in demand and supply of parking spaces.

Using the grant, we built a wearable named Assess, Respond, Monitor, Strengthen (ARMS) glove that facilitates patients to perform various supervised interventions at their convenient place and time without the presence of therapists.

Secure Baggage using Personal Security (PSc) - Runner-up at OpenGovDataHack
PSc is a sensor-based embedded system with BLE, which we built to act as a virtual locker for securing the belongings of passengers using public transports [Link].
PSc was runner-up of NIC-IAMAI #OpenGovDataHack conducted across 7 cities nationwide and qualified for final presentation before Shri Ravi Shankar Prasad, Minister of Electronics & IT, Government of India.
PSc was nominated for Tata Consultancy Services (TCS) best project award.
Also participated in Smart India Hackathon by The Ministry of Civil Aviation, India.
Smart Portable IoT Vaccine Monitor - 2nd place at Mouser IoT Design Contest
When the environment is not optimal, the efficacy of vaccines is lost, especially when health workers carry vaccines in a portable box during door-to-door polio campaigns. The designed 'Smart Portable IoT Vaccine Monitor' continuously monitors the vaccines using multiple sensors and runs local analytics to ensure vaccine efficacy is preserved. The timely alerts from our device prevent administering less potent vaccines during campaigns. This proposed concept and prototype won second place at Mouser IoT Design Contest, National level, India [Link].
Gesture Control Glove - Finalist at Atmel Embedded Design Contest
During seminars/presentations, to provide a seamless user-machine interaction, we built a wireless sensor-based wearable that helps the presenter achieve improved synchronization while performing presentation control tasks such as window switching, scrolling, slide navigation, audio-video controls, etc. This proposed 'Gesture Control Glove' wearable was the finalist at the national level (India) 'Embedded Design Contest' organized by 'Atmel Semiconductor' [Cert].
