Job Success
Cartagena, Colombia - 5:37 pm local time
I’m passionate about turning ideas into reality through embedded systems design. Whether it’s developing firmware or PCBs, I create reliable, efficient, scalable, secure, and easy-to-maintain solutions.
My work focuses on ARM microcontrollers in C/C++. From prototyping and testing to final production, I’m hands-on in delivering firmware and hardware solutions that work seamlessly together.
Skills and expertise:
- Firmware development: Proficient in creating firmware for ARM, AVR, and PIC microcontrollers in bare metal, event-driven, state machine, and RTOS (FreeRTOS, Zephyr) architectures and MISRA C compliance.
- PCB design: Experienced in designing multi-layer PCBs using Altium, KiCad, Eagle, and EasyEDA. Familiar with selecting components based on specifications, availability, and cost.
- IoT: Experienced in integrating IoT devices with cloud services like AWS and Azure. Knowledgeable in BLE, BLE Mesh, WiFi, HTTP, HTTPS, MQTT, CoAP, and others.
- Embedded UI: Capable of developing UIs for resource-constrained environments using LVGL, TouchGFX, QT, and Embedded Wizard.
- Peripherals: GPIO, UART, I2C, SPI, PWM, Timer, ADC, DAC, Watchdog, DMA, RTC, PLL, CAN, USB, and CRC.
- Embedded Linux: Experienced in creating tailored Linux distributions and device drivers, familiar with build systems like Yocto and Buildroot.
- Security: secure boot, firmware encryption, authentication protocols, and best practices for secure firmware updates.
- Mobile app integration: Capable of programming microcontrollers for seamless communication with mobile applications.
- Version control: Git and GitHub for managing source code and teamwork.
- Microcontrollers: ESP32 / ESP32-S2 / ESP32-S3 / ESP32-C3 / TTGO T-Camera / ESP8266 / Nordic nRF52 DK / nRF24L01 / STM32F4xx Nucleo Board / STM32F1xx / STM32F3xx / STM32H7xx / Arduino Uno / Mega / Nano / TI MSP432 Launchpad Board / MSP430G / MSP430FR / NXP FRDM-KL25Z Board / Raspberry Pi / BeagleBone Black / PIC16 / PIC18 / PIC32
If you need a skill that isn’t listed, just ask. I’m a fast learner and can quickly get up to speed with new technologies and protocols by diving into the technical documentation.
My lab is fully equipped with all the essentials—oscilloscope, power supply, multimeter, and soldering station—so I can test hardware and speed up prototype development.
You can check out my GitHub portfolio (@juanpgg-git) to see my work in areas like bare metal programming, FreeRTOS, HAL API, ESP-IDF, and Nordic SDK.
Whether working solo or as part of a team, my goal is to deliver top-notch embedded systems that exceed expectations. If you’re developing a new project or enhancing an existing one, let’s connect! I’d love to discuss your needs and show you how I can make a difference. Drop me a message, and we’ll get started.
