Work History

Embedded Software Engineer

Comcast
Philadelphia
02.2025 - Current
  • Designed and developed embedded software for ECUs used in hybrid vehicle powertrain systems using C/C++ on ARM Cortex-M MCUs.
  • Integrated and optimized FreeRTOS for real-time control tasks, including task scheduling, inter-process communication, and memory management. Developed device drivers for SPI, I2C, UART, CAN, and PWM modules to support sensor integration, motor control, and diagnostics.
  • Collaborated with hardware and system teams to define software-hardware interface specifications, and debugged board bring-up issues using oscilloscopes and logic analyzers.
  • Contributed to bootloader development with a secure firmware update over CAN (UDS protocol).
    Conducted unit and integration testing using VectorCAST and static analysis with MISRA-C compliance tools.
  • Led root cause analysis for real-time issues, such as watchdog resets, timing jitter, and task starvation.
  • Documented software requirements, design, and verification protocols in line with ASPICE and ISO 26262 standards.
  • Designed and developed scalable RESTful APIs and GraphQL endpoints for aerospace data exchange and real-time communication.
  • Implemented comprehensive testing strategies using Jest for unit testing, and Cypress for end-to-end testing.
  • Collaborated with cross-functional teams in an agile environment, participating in sprint planning, stand-ups, and retrospectives.
  • Optimized application performance through efficient caching strategies and database query optimization in DynamoDB.
  • Applied security best practices in cloud-based applications, including proper authentication, authorization, and data encryption.

Embedded Software Engineer (Intern)

S&P Global
05.2023 - 03.2024
  • Developed firmware for battery-operated IoT sensor nodes used in smart factories for temperature, vibration, and humidity monitoring.
  • Designed low-power embedded applications with less than 20 µA sleep mode current, using STM32L4's ultra-low power modes, and wake-on-interrupt techniques. Programmed BLE and Wi-Fi connectivity stacks, enabling real-time sensor data transmission to AWS IoT Core using MQTT over TLS.
  • Implemented an OTA firmware update mechanism over Wi-Fi, with rollback and integrity check features using SHA256.
  • Interfaced with MEMS sensors over I2C/SPI; wrote custom drivers, and calibration routines for real-time measurements.
  • Built real-time data acquisition and control loops using FreeRTOS, managing task priorities, queues, and event groups.
  • Developed diagnostic CLI over UART and implemented Modbus protocol for local debugging and calibration.
  • Optimized firmware to extend battery life up to 1 year, using deep sleep modes and sensor polling algorithms.
  • Created touchscreen GUIs using LVGL for a handheld diagnostic device interfacing with the sensor nodes via BLE.
  • Contributed to hardware-software bring-up, using oscilloscopes, logic analyzers, and firmware stubs for validation.
  • Supported end-to-end product lifecycle, from prototyping and field testing to production release and remote debugging.
