Greetings, I hold a Ph.D. and I am a seasoned patent analyst, 3D modeler, inventor and product designer in New York. I have provided technical writing and illustrations for over 100 patents for 'pro se' inventors who represent themselves to the patent office. I hold a paralegal certificate and I often work under the supervision of attorneys, collaborate with engineers and innovators. I can go from design work to reverse engineering (using scanners), to prototype printing (8k resolution, resin and filament 3D printers), to fabrication drawings. I have also drafted user manuals and technical documentation and perform artificial intelligence prompt engineering. I am also a scientific author and illustrator specializing in technical writing, medical illustrations, statistics, grant writing, CAD drawings, proof-of-concept designs, as well as parametric mechanical designs. I utilize subscriptions for both AutoCADLT and Fusion360 routinely. I only accept a limited number of projects at a time so that I can maintain the quality and quick turnaround my clients have come to expect. Please know that I am NOT an attorney OR a registered patent agent, and I do NOT dispense legal advice or represent ANYONE to the USPTO - I only write technical content for those who chose to file themselves and my work is educational in nature. Thank you.

Delivered 100+ embedded & IoT products across healthcare, smart home, and industrial automation. Expert in STM32, ESP32, NRF, BLE, LoRaWAN, and edge AI. Focused on low-power firmware, secure connectivity, and production-ready hardware. Reliable Embedded Products from Prototype to Production With over 9 years of experience in embedded systems and IoT development, I support businesses building connected devices - from early PoC to cloud-connected, scalable solutions. My clients range from startups to industry leaders in smart agriculture, medtech, energy, and consumer electronics. I’ve led and contributed to 100+ embedded projects, helping clients reduce time-to-market, optimize power consumption, and meet high performance, security, and long-term maintainability standards. Custom Hardware Design & Power-Efficient Embedded Systems I specialize in the design of custom PCBs and low-power electronics using platforms like STM32, ESP32, Nordic, etc. Most of my hardware is built around multi-layer Altium or KiCad layouts with a strong focus on signal integrity, thermal design, and EMI shielding. For mobile and remote applications, I design energy-autonomous systems that combine DC/DC regulation, battery management, solar panels, and wind-based charging. Wireless connectivity is a core part of nearly every device I build using BLE, LoRaWAN, Zigbee, LTE-M, NB-IoT, and Wi-Fi depending on the use case. I also integrate wired protocols such as CAN, RS-485, and Modbus for industrial environments. Sensor integration includes everything from IMUs and PIRs to GPS, air quality, pressure, light, optical, and biomedical-grade sensors with full calibration and noise filtering handled on-device. I’ve developed systems that run reliably in the field for 2+ years on a single battery cycle. Embedded Firmware, RTOS, and OTA Infrastructure My firmware is built on Embedded C/C++ (and sometimes MicroPython), often on FreeRTOS or Zephyr. I’ve built dozens of projects involving custom driver development, power-optimized sensor sampling, OTA update systems, real-time control loops, and secure wireless communication. Projects include: A wearable emergency-detection bracelet with heart rate and GPS An STM32-based mesh-connected lamp post system with solar/wind autonomy A LoRa-enabled smart agriculture node using multiple sensor types with BLE backup OCR-based utility meter reader with edge-based image processing and local AI Where needed, I also implement OTA bootloaders with encryption, failover handling, and remote update diagnostics. Edge AI & Computer Vision for Smart Devices Several of my recent solutions have used embedded computer vision or AI logic on-device. I’ve implemented TensorFlow Lite and custom CNNs on Raspberry Pi and STM32-based platforms to enable real-time inference, including: OCR and character detection for meter reading Gesture detection and occupancy tracking Anomaly detection in air quality and power usage These edge AI systems allow for minimal cloud traffic and faster, more private decision-making directly on the device. Cloud-Connected Systems & IoT Security My clients rely on secure, scalable communication between devices and the cloud. I’ve worked with AWS IoT, Azure IoT Hub, ThingsBoard, and Tuya for remote device control, data storage, and analytics. I implement MQTT, HTTPS, and other lightweight protocols with end-to-end encryption and secure provisioning. I also design systems with Tuya Smart platform integration deployed in over 50 projects in smart home and automation domains to ensure compatibility, remote control, and user-friendly setup. Security isn’t an afterthought it’s part of the architecture. I use encrypted communication, signed OTA packages, and secure firmware boot strategies to reduce exposure to vulnerabilities in the field. From Prototypes to Production-Ready Solutions I support clients through prototyping, iteration, and scale-up including enclosure-ready 3D models, functional testing, and BOM optimization. I work with reliable manufacturing partners in the US, EU, and Asia for pilot runs and small-batch production. Let’s Discuss Your Next Embedded Project Whether you're developing a new wearable, a remote monitoring device, or an industrial automation tool, I bring a full-stack embedded mindset, technical depth, and reliable delivery. Ready to turn ideas into real-world hardware? Let’s talk.
