With 3+ years of hands-on experience, I specialize in taking embedded products from prototype to mass production. I've completed 10+ real-world projects and successfully shipped consumer products that are now in end-users' hands. What I Do Best I build production-grade firmware — not hobby projects. My work spans the full embedded stack: hardware bring-up, device drivers, firmware, bootloaders, OTA systems, and companion mobile/PC apps. Core Expertise - MCU Platforms: STM32 (F0/F1/F4/L0/L4), ESP32/ESP32-S3/ESP32-P4/ESP32-C3, nRF52480/NRF52832, ARM Cortex-M & RISC-V, ... - RTOS & Bare-Metal: FreeRTOS (advanced task sync — queues, semaphores, event groups, task notifications), bare-metal programming, custom bootloader development, ... - Peripherals: I2C, SPI, I2S, UART, PWM, ADC/DAC, RMT, Modbus RTU, USB HID, ... - Connectivity: Wi-Fi, BLE, LoRa, NFC, GSM/GPRS, NB-IoT, 4G, ... - IoT & Cloud: MQTT, HTTP/HTTPS, WebSocket, TCP/UDP | Azure IoT, AWS, Firebase, ... - Security: Secure Boot, encrypted NVS storage, FIDO2 passwordless authentication - Languages: C/C++ (primary), Python, Dart/Flutter (mobile & desktop apps), Java - Sensors: Accelerometer, IMU, Gyroscope, Time-of-Flight (ToF), Fingerprint, Ambient Light, Temperature, Humidity, Water Quality, Gas, Heart Rate & SpO₂, ... - Peripherals: Camera, Microphone, Speaker, Buzzer, ... - Displays: TFT, OLED, LCD, HMI, ,.. - Build & Debug: ESP-IDF, Makefiles, CMake, linker scripts, GCC toolchain, GDB/JTAG — fully IDE-independent - Other: Embedded Linux (Raspberry Pi, Orange Pi), Edge AI on MCUs, VoIP, WireGuard VPN, OTA update systems, PCB design (EasyEDA) What Sets Me Apart I deliver production-ready firmware, not proof-of-concepts. Clean architecture, proper error handling, memory optimization, and power management. I work at the toolchain level — Makefiles, linker scripts, GCC, GDB — not dependent on any IDE. I collaborate effectively with backend teams, including building systems using MCP (Model Context Protocol). I've shipped real consumer electronics — I understand what it takes to go from "it works on my bench" to "it works in 10,000 units." If you're a startup building a hardware product and need someone who can take it from prototype to production, let's talk.

I’m a senior software developer from Portugal with more than 20 years of experience building commercial desktop and mobile applications. I help teams build, stabilize, refactor, and extend products that involve real technical complexity. My work is focused on desktop and mobile software where senior technical judgment matters: Qt/C++ applications, native iOS and Android apps, performance-sensitive features, media and audio/video pipelines, computer vision, hardware integration, OS-level behavior, and long-term maintainability. I have worked on commercial products used by real customers, including projects such as Rocketbook - Document Scanning, Triller - Music Video Social Network, ROVR Radio - Audio Production & Dashboard, Toby - AI Real-Time Audio Translation, iContact - Camera Widget, VideoShop - Video Composition, iGreet - Augmented Reality Greeting Cards, LeanStreamer - Multiple Audio Encoding Streaming Tool, BigRoom - Automated AI Editor, and other desktop and mobile applications that required reliable implementation and careful technical decision-making. Clients usually hire me when they need help with: • building a desktop or mobile product properly from the ground up • refactoring an existing codebase without unnecessary rewrite risk • solving platform-specific issues that are blocking progress or release • implementing complex native features involving camera, audio, video, files, hardware, or OS APIs • improving architecture, maintainability, performance, and stability • adding senior technical depth to an existing team or codebase My core expertise includes Qt/C++, desktop software, native iOS and Android development, software architecture, refactoring, performance optimization, media processing, computer vision, and hardware or platform-level integration. I’m especially well suited for products that already exist and now need to be improved carefully. That may mean stabilizing a codebase, modernizing architecture, solving difficult technical issues, or extending the product in a way that remains clean and maintainable. I care about building the right foundation early, keeping the codebase understandable, and making technical decisions that still make sense in the long run. If your product already exists and needs senior technical help to move forward safely, I’d be glad to discuss it.
