I build two things that rarely come from the same person: embedded hardware that ships, and AI systems that run real businesses. On the hardware side, I design end to end. Custom PCB in EasyEDA through JLCPCB manufacturing (BOM, Gerber, CPL), then the firmware that runs on it: ESP32 S3, C3 and C6, FreeRTOS dual core architecture, BLE, WiFi, MQTT, OTA updates, ultra low power design. Seven custom boards manufactured with full SMT assembly, 10K+ lines of production firmware, one patent filed with 226 claims on adaptive battery management with Edge AI, and a published research paper on wireless power infrastructure. On the AI side, I build agents that do real work, not demos. I currently run an autonomous business agent in production for a service business: it handles customer conversations on WhatsApp, books appointments through calendar integration, reads payment receipts with vision AI, and reconciles the money at the end of the day, with a human takeover bridge through Telegram. Multi tenant architecture, ready to onboard new businesses. I also build algorithmic trading systems with full ML data pipelines, where every strategy is validated against out of sample data before it touches a live account. What clients get from me: someone who understands the whole chain. The sensor, the board, the firmware, the radio, the backend, the AI layer, and the business result it has to produce. I flag risks early, I document everything, and I deliver with receipts, build footage and handover docs the client can actually use. Recent work: BLE triggered hardware prototype delivered ahead of schedule with same day milestone approval, and a LoRa ski tracking device on Heltec hardware

As a Senior Embedded Systems Engineer, I specialize in designing reliable, production-ready embedded solutions that integrate hardware and firmware seamlessly. My expertise covers embedded firmware development, PCB design, FPGA development, and electronic system validation, allowing me to deliver complete solutions from concept through manufacturing. I have experience developing battery-powered embedded devices, BLE-enabled products, custom PCB designs, FPGA-based digital systems, and power management circuits. I also help clients troubleshoot complex hardware issues, optimize circuit performance, and improve system reliability through careful debugging and validation. My technical expertise includes: • Embedded Firmware Development • Embedded Systems Design • PCB Design & Schematic Capture • FPGA Development (VHDL/Verilog RTL) • BLE & Wireless Embedded Devices • Battery-Powered Electronics • Power Management & Voltage Regulation • Circuit Simulation & Hardware Debugging • Prototype Development & Product Validation I believe successful embedded products require both strong hardware engineering and reliable firmware. By combining these disciplines, I build efficient, maintainable, and scalable systems that are ready for real-world deployment. Whether you need a new embedded product designed from scratch, firmware for existing hardware, PCB development, or assistance debugging complex electronic systems, I am committed to delivering high-quality engineering solutions with clear communication and dependable results.
