Hi, I am an Electronic Engineer with solid experience in designing, developing, and troubleshooting electronic systems. I specialize in embedded systems, PCB design, IoT, and automation. I help clients turn ideas into real, working, and reliable products, from concept and schematic to prototype and testing. I combine engineering precision with practical problem solving, so every solution is efficient, optimized, and ready for real-world use. Core Expertise: Electronic and Hardware Engineering: 1. Circuit design (analog and digital) 2. Schematic capture and PCB layout (KiCad, Altium, EasyEDA, Eagle) 3. Power electronics and DC–DC converters 4. Sensor integration and signal conditioning Embedded Systems: 1. Microcontrollers: ESP32, Arduino, STM32, PIC, AVR 2. Firmware development using C, C++, and Embedded C 3. Real-time and low-power embedded applications 4. Debugging, testing, and optimization of firmware IoT and Automation: 1. Wireless communication: WiFi, Bluetooth Low Energy (BLE), LoRa, Zigbee 2. IoT device prototyping and integration with cloud platforms 3. Home and industrial automation solutions 4. Remote monitoring and data acquisition systems Prototyping and Testing: 1. Breadboard and PCB-based prototyping 2. Hardware validation and troubleshooting 3. Performance, reliability, and cost optimization 4. Clear documentation for assembly and future development Why work with me: 1. Clear and responsive communication 2. Professional and detail-oriented engineering work 3. On-time delivery and reliable support 4. Flexible: from small fixes to full product development 5. Focused on long-term cooperation and client satisfaction Let’s work together: If you need help with PCB design, embedded firmware, IoT devices, or a complete electronic system, I am ready to support your project. Feel free to send me a message with your idea or problem, and I will be happy to discuss the best technical solution for you.
