🔧 Embedded / Firmware Engineer with hands-on experience in bare-metal MCU bring-up, peripheral driver development, cellular IoT integration, secure cloud connectivity, and system-level debugging.

• End-to-end development of an embedded IoT telematics system
• Bare-metal bring-up on PIC32CX SG61 (Curiosity Ultra)
• Peripheral drivers: GPIO, Timers, Interrupts, UART, SPI, ADC, PWM, I²C
• Cellular integration using EC200U-CN (GPS, SMS, cloud data)
• Secure cloud communication: MQTT, HTTPS, TLS/mTLS, SAS tokens
• Debugging: AT commands, SSL/TLS issues, payload formatting, network behavior
• System integration, stabilization, and technical documentation

⚠️ Company firmware and internal tools are protected under NDA; no proprietary code is published.

Academic, self-built, and experimental work used to strengthen embedded and communication fundamentals.

• Smart Lighting System – sensor-driven automation logic
• Wearable Obstacle Detection System – real-time sensing and alerts
• Bare-metal PIC32CX peripheral driver development (learning & validation)

• AES–DES–RSA Hybrid Cryptographic Model
• Spectrum sensing algorithms for cognitive radio networks

• +5V to +3.3V Voltage Regulator PCB (Altium Designer)
• MCU–sensor interfacing and pin multiplexing

• Bare-metal firmware for MCUs (PIC32CX, STM32)
• Peripheral drivers (GPIO, ADC, DMA, Timers)
• Cellular IoT systems (EC200U, MQTT, HTTPS)
• Secure cloud-connected embedded systems
• Well-documented, reproducible engineering workflows

Public repositories focused on generic, self-built, NDA-safe firmware engineering, inspired by industry practices.

Purpose:

• Register-level peripheral programming
• Interrupt handling & NVIC concepts
• ADC (polling vs DMA): theory + examples
• Debugging techniques (common mistakes & fixes)
• Clean firmware folder structure
• Engineering notes & best practices

• Enhanced Spectrum Sensing Using Fast Slepian Transform for Cognitive Radio Networks
