I am a professional electronic engineer with 13 years of experience behind my back. Electronics is a wide field with different branches. I've started my career as a power electronics engineer and then I've moved to digital electronics and MCU programming. I also have experience in project management. Two words which characterize me the best - responsible and professional. If you decide to work with me - you will not regret. - Schematic and PCB design Altium Designer, Mentor Xpedition - FPGA, verilog - Data encryption - PCB routing - Embedded C programming - stm32, stm8, cc26xx - Free RTOS, TI-RTOS - PSpice simulation, MATLAB simulation - Power electronics: SCR, Transistor inverters, power supplies - Can provide assistance with various mathematical problems

I'm an experienced researcher in machine learning, artificial intelligence, signal processing, and designing decoders for 5G/6G. I can help you with designing and implementing machine learning algorithms for a wide range of applications (e.g., finance, biology, and energy consumption). I actively contribute to the open source projects. Knows Python, C++, CUDA C++, MATLAB, Linux, TensorFlow, PyTorch, PyQt5, Polars, LightGBM, CatBoost, and XGBoost. I also have experience working with Verilog and FPGAs.

Most IoT hardware projects don't fail because of bad ideas — they fail because the PCB and the firmware were built in silos, by different people, who never talked about DFM constraints or interrupt latency at the same time. At EdgeForge Labs, I close that gap. I'm Jhordan, an Electronics & Automation Engineer specializing in end-to-end intelligent hardware systems. My work spans the full stack: schematic capture and PCB layout in KiCad (DFM-optimized for JLCPCB/PCBWay production), embedded firmware in C/C++ on STM32 (HAL/LL/FreeRTOS) and ESP32 (ESP-IDF), IoT connectivity (BLE, MQTT, LoRaWAN, OPC UA), and — where performance demands it — TinyML models deployed directly on the microcontroller. What I build: → IoT Product Prototypes: From concept to a manufacturable, firmware-complete hardware prototype. I handle component selection, schematic, PCB layout, BOM management, and bring-up firmware — all designed for the day your product scales beyond the prototype. → TinyML & Edge AI Systems: I deploy optimized ML inference directly on STM32 and ESP32 — no cloud dependency, millisecond latency. Projects include predictive maintenance (RUL estimation from vibration data), neural network control systems, and real-time anomaly detection. I handle the full pipeline: dataset preparation, model training in Python, quantization (int8), and deployment in efficient C++ firmware. → Industrial IIoT & SCADA Modernization: I connect legacy PLC infrastructure (Siemens, Rockwell, Schneider) to modern IT systems via OPC UA, Modbus TCP, and PROFINET. I design high-availability SCADA architectures, implement redundant PLC control schemes, and build real-time monitoring dashboards that follow ASM (Abnormal Situation Management) standards. My engineering standard: Every deliverable is production-oriented. That means copper pullback specs that don't get Gerbers rejected, firmware architectures that survive field resets, and SCADA systems designed with redundancy before the client asks for it. I work in English and Spanish. My communication style is direct: I flag risks early, document clearly, and propose solutions before you have to ask. If your project sits at the intersection of hardware, firmware, and intelligence — let's talk.
