About Chandsab Sohel Bangi
Developing embedded firmware for IoT-enabled streetlight control systems, improving autonomy and reducing server dependency. Optimized inter-process communication (IPC) techniques and multi-threaded applications, achieving a 25% reduction in system latency. Introduced new features and programming them with extensive logic while utilizing low level C programming with zero crashes. Properly utilizing my DSA skills to develop high quality firmware which reduces RAM consumption of microcontrollers. Designed interrupts and implemented ADCs efficiently so that devices can work and communicate without unwanted reset. Created solutions to handle large data for RAM and Flash memory and implemented them practically which passed all test cases. Interfaced high level sensors and modules such as GPS/GNSS, ALS and temperature sensors with interrupt data extraction and proper utilization of given features. Created innovative solutions such as antitheft, system alerts and resolve, fail-safe mode, low power mode, disconnection handling and saving status data of that time in flash using SPI. Implemented MQTT and TCP/IP protocols for secure and reliable device-to-server communication. Integrated LTE for IoT systems, enhancing connectivity and performance in large-scale deployments. Created myself a testing application using Python without relying on other teams for completing my development seamlessly. Created multiple communication systems such as MQTT and SMS on the single LTE module for preventing disconnections and network dependency while providing all features in both communications. Collaborated with cross-functional teams to refine features, achieving a 20% improvement in overall system reliability.
