A skilled software developer, on various platforms ranging from Windows to Linux to ARM and other embedded devices (AVR, PIC, etc). My preferred programming languages include, but are not limited to: - C/C++ - Java - Python - Rust - C# - Matlab I'm familiar with various open source libraries in different programming languages such as STL, Curl, Json, GTK, Swing, BeautifulSoup, Requests, Selenium, Tkinter, and many more... I've experience in Embedded Software using various microcontrollers (AVR, PIC, STM32, TM4C123, etc...). I've used many peripherals such as (GPIO, Timer, PWM, NVIC, RCC, FPEC, UART, SPI, I2C, CAN, ADC,...), interfaced it with many sensors and actuators. I've built many projects ranging from simple projects (blinking LEDs, motor control, calculator, stop watch, ...) to more advanced projects (Bootloader, Smart Home, Digital Clock, ...). I have a strong background about Algorithms and Data Structures such as: - Dynamic Programming - Backtracking - Graphs - DFS - BFS - MST - Heap - Trie - Balanced BSTs - Segment Trees - Disjoint Set - and many more...

My primary focus in writing software is performance, without sacrificing the safety and security of the application. I will do my best to discuss all the relevant details and the scope of the project with the client, so that I can form an idea of the finished product in order to be able to lay a better groundwork design for the project.

10+ years turning PLC/HMI/SCADA specs into systems that run reliably from day one. I've personally been the lead control engineer on projects ranging from wastewater treatment automation for Melbourne Water (Australia) to instrumentation support on Argentina's RA-10 nuclear research reactor. Behind me is AutoSolve, my engineering team in Argentina, so you're not betting the project on one person's bandwidth. Clients consistently point to the same thing: no surprises, clear communication, delivered on time — "Dardo and his team turned this telemetry project into a game changer for our company," as one client put it. Platforms: Siemens TIA Portal (S7-1200/1500), Rockwell Studio 5000/FactoryTalk, Beckhoff TwinCAT 3, Schneider EcoStruxure, Unitronics VisiLogic/UniLogic, Ignition SCADA. IIoT/edge: Raspberry Pi, industrial IPCs, MQTT, OPC UA, Modbus, EtherNet/IP — from PLC logic to the dashboard, ERP, or cloud your data actually needs to reach. Engagement models: turnkey project, team extension, or staff augmentation. Send me your current setup and goals, and I'll propose the fastest, lowest-risk path to deliver.

I am a senior electronics and embedded systems engineer with 47 years of experience in hardware design, firmware development, PCB layout, debugging, testing, and product development. I help clients turn electronic product ideas, prototypes, and hand-wired circuits into working embedded systems and manufacturable PCB designs. Typical projects I can help with include: * ESP32 and STM32 / STMicroelectronics MCU-based products * Power conversion and low-power battery-powered product design * Custom wireless and RF communications, including LoRa and ESP-NOW peer-to-peer networking * Circuit design and component selection for manufacturing * Schematic entry and multi-layer PCB design. * Ordering fabs and coordinating assembled boards. * C/C++ firmware for sensors, displays, audio, wireless, and control systems * Embedded graphics and touchscreen user interfaces using LVGL * Digital audio filtering, FFT spectrum analysis, and voice activity detection * Cloud API integration for speech-to-text, text-to-speech, and language translation * Embedded bus and peripheral interfaces: I2C, SPI, I2S, UART, RS-485, CAN, and SD/MMC * Prototype debugging and board bring-up * Converting breadboard prototypes into clean PCB designs * Design reviews before manufacturing * Analog and digital circuit troubleshooting * Production-oriented improvements for reliability and manufacturability I have founded and managed engineering companies and consulting firms, led technical teams, and helped bring electronic products from initial concept through prototype, testing, manufacturing, and production. For clients, this means fewer design mistakes, faster debugging, lower development risk, and a clearer path from concept to a working, manufacturable product.

Software development isn't just my profession—it's what I've been building companies around for more than 28 years. I specialize in projects that other developers consider too difficult, too specialized, or too risky.
