About
I make things
actually work.
I'm Fayyaz - an Embedded Systems & Firmware Engineer who ships production-ready code that runs on hardware. Not prototypes. Not demos. Real firmware for IoT devices, medical tech, and industrial systems.
From porting the Helix MP3 decoder to ESP32-S3 to building a trilingual speech recognition pipeline on NVIDIA Jetson Nano, I work at the exact boundary where software meets the physical world - where a bug isn't just a ticket, it's a consequence.
Currently pursuing B.Tech in Electronics & Telecommunications at S.P.I.T. Mumbai, while building audio playback systems at Kahani Toys. IIT Bombay-affiliated research project in parallel. Executive Head of the IEEE Student Chapter.

Work Experience
Where I've
built real things.
Kahani ToysSep 2025 → Sept 2026
Embedded Systems Engineering Intern
- Engineered 3+ audio applications on ESP32-S3 using MAX98357 I2S Audio Decoder for .wav & .mp3 playback
- Implemented BLE+WiFi coexistence for audio controls, SD card file management, and wireless MP3 streaming
- Improved audio quality by up to 90% by introducing automatic mono/stereo mode switching
- Ported the Helix MP3 Decoder to ESP-IDF (Xtensa), building custom partition table layout for multi-format audio handling
VISOMay 2025 → Aug 2025
Embedded Firmware Intern
- Engineered industrial automation firmware on STM32F3/F4/H7, integrating 24-bit ADC (MCP3564) via SPI with USB CDC for live data acquisition at RMSE < 5%
- Built a 3-language (EN/ES/JP) speech-to-text pipeline on NVIDIA Jetson Nano using Vosk & Whisper - 95% accuracy with Modbus TCP control
- Integrated Bluetooth Classic on ESP32 for wireless speaker connectivity
- Interfaced GPS module for a real-time bus navigation system across 20+ locations in India
SMOWCODEDec 2023 → May 2024
Embedded Systems Developer Intern
- Developed PID control library on ESP-IDF for ESP32 maintaining < 3% steady-state error
- Built a C-to-graphical code bridge that reduced development time by nearly 10×
- Implemented UART communication firmware on NXP S32K144
- Designed bit-banged software I2C & SPI drivers on ESP-IDF, verified against hardware output at 90% efficiency
Projects
Things I
created.
“The best way to understand hardware engineering is to put it in front of someone who's never touched a soldering iron and watch what they build under pressure.”
B.Tech Major Project · IIT Bombay Affiliated
Smart Hand Physiotherapy System
Designing a smart rehabilitation system using IMU sensors with RMSE < 5% to track real-time elbow & wrist movements. Associated with the Department of Electrical Engineering, IIT Bombay.
Jan 2026 → Present
Industry Collaboration Project
Smart Power Monitoring System
Calibrated 10-bit ADC of PIC18F4550 to measure 0–250V AC, 0–70V DC, 0–5A AC/DC. Integrated INVT HMI Display for live data and manipulated PWM duty cycle via Modbus RS485.
Jan 2026 → Apr 2026
Hobby Edge AI Project
Gembot - Gemini Voice Assistant Bot
Designed a real-time voice-controlled assistant bot with GPU-based local audio processing. Achieved a 70% reduction in response latency over cloud-only pipelines.
Dec 2025 → Jan 2026
Hobby Project
Scarlet Rover - Mini ADAS System
Built a mini ADAS rover with Adaptive Cruise Control, Collision Assist, and Lane Assist using MSP430FR5969. Also created an ESP32 gesture-control car using MPU6050 via I2C.
