Contactless IR Temperature monitoring - battery powered device (WiFi, Bluetooth) |
Software, hardware and device prototyping of a contactless temperature monitoring device. ( links ) . The device was developed in multiple variants - based on EspressIF ESP32 (WiFi+Bluetooth), ESP8226 (WiFi only), STM32 (Wifi+eSim Cellular) and was a battery powered device which could perform non-contact temperature monitoring using an IR-Melexis sensor connected through an I2C/SPI interface to the main board. The project involved developing the application software to read from the IR sensors through multiple actuators or scheduled reads and transmit this data to a AWS IoT Core cloud service through MQTT. The cloud software was also developed to write the data from these devices to S3 and Dynamodb and show this data in real-time over a BI dashboard. |

Locixx GmbH Personal Location Tracking |
The personal tracker watch is battery powered and connected to a cellular network through a SIM. The tracker sends location information to configured clients through TCP at scheduled intervals or whenever there is an SMS trigger. The project involved writing a parser for the TCP packet arriving from the watch and reading the GPS information - such as latitude, longitude, strength, heading, number of satellites latched, etc. . This data was then saved to a cloud database (MySQL) to be read by an application upon search requests. |

OBD-II Vehicle Location Tracking |
The project involved end-to-end solution development for a location tracking and driving behavior analysis. The OBD device could read the vehicles CAN bus information as well as provide accelerometer and position data. The project involved integrating these fleet of devices to a cloud backend and aggregating data to be made available to an end application. |

Embedded Software Projects: Multimedia codecs optimizations and Media systems development on ARM Cortex and TI-DSP based processors |
These were multiple long duration projects spread over multiple years. Multimedia Codec Optimizations: Codecs such as MP3, H264 are typically written in C/C++ language. To run these codec softwares on low-power devices such as those enabled by ARM-Cortex-A8 or TI-DSPs needs both compute and memory optimizations to enable real-time encoding or decoding. Understanding the processor architecture and Memory I/O are key to determining the optimization approach. System development: Development of Audio/Video playback systems, Video-VoIP communication systems on ARM and TI based processors. Have worked on optimizing components, memory/cache optimizations, system integration on ARM7/9/9E/11 and TI-C64x processors. Competent with ARM and TI-C64x+ platforms. OpenMAX IL, Gstreamer, TI Media framework, TI BIOS, TI Code composer studio, ARM-linux, ARM ADS, linux makefiles |

General Management @ Vodafone Idea Ltd. |
This was a greenfield project for the largest Indian Telecom - Vodafone Idea Cellular Ltd. It involved setting up an OTT platform from scratch including managing RFP and RFQ processes, multi-vendor evaluations, handing out projects and services to various vendors and managing their deliveries and output, working with commercial and product teams to make progress. Vodafone and Idea underwent a merger and I was responsible for technology and live-service merger of Telecom Value Added Services and Digital Services. I handled Data Asset Monetization programs with multiple vendors in advertisement, finance-credit-rating, weather-forecasting and similar verticals who leveraged Machine-Learning over telco data for improving services. |
July 2016 to Sep 2019 |

Product Management @ Mediamelon Inc. |
Started from a PoC and few patents to defining the product and implementing it in a way that it can fit the industry offering. Worked with multiple industry folks and CTOs of partner companies to create and publish joint collaterals and define the product in a way that it becomes easy to adopt. Deeply involved with hiring and bringing the right folks into the organization. |
June 2013 to Aug 2016 |

OTT Video Service Analytics & Real-time anomaly detection Mediamelon, Inc |
The project involved architecting and implementing a real-time system which can work with real-time messages of the high-order and frequency and is able to detect anomalies in real-time. The size was of the order of 1k to 3k messages per second where each message has 100+ parameters. Kafka and KSQL were utilized to implement this system and custom KSQL UDF functions were written which could run ML prediction models to predict the anomalies. |

QBR Video Streaming Technology Mediamelon, Inc |
QBR is a new technology which improves the Adaptive bitrate video streaming methods like HLS and MPEG-DASH by reducing the CDN cost and improving the quality. I worked on multiple aspects to get this product into market - building PoC, optimizing the usage, making it suited to partners, integrations, working with DRM/Video-Encoder/OTT-Platform vendors and also recruiting and working with marketing teams - among other things. It also led to a granted patent which covers various aspects of enabling this technology for real-time live streaming. |

Industrial IoT Process Adherence through Camera Surveillance Systems, ConnectedThinks Pvt Ltd |
A system was developed for manufacturing industries having multiple manual assembly tasks. Where in-depth inspection is not feasible, it is difficult to ensure the quality of the manual tasks or to get a reliable quality score. An innovative solution was designed where a Video surveillance system would capture the staff’s hand movements, during the assembly process. A Edge device predicts the position and movements on hands and classifies it to certain pre-trained assembly steps. Finally provides a score to the assembly step which is used for inspection and quality improvement. |
