Vedant Kachhadiya

Embedded Software Engineer with 3+ years of experience delivering production firmware for EV charging infrastructure, elevator systems, industrial/medical devices, and IoT gateways. Proven track record tuning BLDC motor control loops, building MQTT/HTTP OTA update pipelines, and architecting ISR-safe, fault-tolerant firmware for field-deployed hardware. Skilled across 32-bit ARM (STM32, Renesas RA) and Xtensa (ESP32) platforms with strong grounding in real-time debugging, state machine design, and communication protocols (UART, Modbus RTU, CAN, MQTT).

Embedded Software Engineer at Philbrick Technologies (India) Pvt. Ltd (2025-04 – Present)

• DC Control Board: Engineered a multi-protocol firmware stack (CAN vehicle handshake, Modbus RTU energy metering, UART TFT display) for DC EV chargers, and implemented real-time fault detection (temperature, three-phase voltage, RCD) and flash-based session storage to support reliable, field-deployed charging sessions with MQTT-based mobile app connectivity.
• AC Control Board: Developed the AC charging control board firmware, integrating Modbus RTU/RS485 communication with the AC driver and TFT display, and delivered OTA firmware update support that reduced the need for on-site reprogramming during field updates.
• AS360 IoT Gateway: build an ESP32-STM32 IoT gateway to bridge CAN-bus elevator telemetry to MQTT, enabling real-time monitoring, dual-MCU OTA updates, and reducing on-site visits by exposing remote fault diagnostics.
• Elevator COP/LOP Panel: Designed the state machine and UART/CAN communication firmware for Car Operating Panel and Landing Operating Panel displays, implementing ISR-safe deferred flash writes that eliminated floor-value data corruption previously caused by writes issued from interrupt context.
• Door Motor Control Drive: Tuned a BLDC six-step commutation and PI speed control loop (ST MCSDK) for elevator door motors, adding obstruction, stall, and overcurrent fault detection with safety interlocks to deliver smoother, more reliable door open/close operation.

Embedded Engineer, R&D Department at Discrete Circuits Private Ltd (2024-03 – 2025-02)

• RF Generator: Programmed an 8051-based control panel interface with DWIN TFT displays for a medical-grade RF generator, meeting reliability requirements for clinical use.
• Remote Unit Display: Developed seven-segment display firmware to present critical operating parameters (code, QTY, SNS, FAT, amount, rate) in real time, improving operator accuracy and reducing manual read errors.
• Coil Detachment Controller: Built fail-safe embedded control firmware for a precision interventional-radiology device used to detach embolization coils, implementing precise current/voltage sensing and real-time signal monitoring to ensure patient safety and regulatory-compliant reliability.
• JALAM: Delivered an industrial water quality and quantity monitoring system (pH, TDS, flow, hydrostatic, chlorine, turbidity sensors) with MQTT-based cloud integration, enabling real-time data acquisition for sustainable resource management.

Embedded Software Intern - R&D at Thingslista Automation LLP (2023-06 – 2024-02)

• Contributed to firmware design, hardware-software integration, testing, and debugging for microcontroller-based systems as part of the R&D team, gaining hands-on exposure to the full embedded development lifecycle.

Embedded Trainee Engineer at Energy Cloud Technology (2022-12 – 2023-04)

• Developed embedded controller firmware and supported PCB design, focusing on system optimization and functional reliability.
• Gained hands-on experience in testing, debugging, and cross-functional hardware-software collaboration.
