Hire the Best Internet of Things Specialists
in the United States

13 years of experience in all aspects of RF design and high-speed PCB development, including antennas, RF front-end circuits, RFID systems, BLE/Wi-Fi/LoRa products, RF components, impedance matching, filters, amplifiers, RF switches, baluns, and antenna tuning. Much of my work has involved RF PCB design, wireless product development, and high-speed digital hardware. This background also extends to RFID readers, transponder-based systems, and FPGA-related hardware projects. I have strong experience in RF and antenna simulation using tools such as HFSS, CST Studio Suite, and Ansys tools for antenna design, RF matching, radiation pattern analysis, impedance optimization, RF front-end validation, and wireless performance improvement. I have strong experience in high-speed PCB design, including multilayer board layout, controlled impedance routing, differential pairs, signal integrity, power integrity, EMI/ESD protection, RF grounding, shielding, and manufacturability. I have worked on FPGA-related projects involving Xilinx, Zynq, Artix-7 FPGA platforms, including data acquisition, signal processing, timing-sensitive interfaces, and high-speed digital board design. My embedded hardware experience includes the setup, integration, and debugging of microcontrollers and embedded platforms such as STM32, ESP32, ESP32-S3, Nordic nRF52832/nRF52840, Raspberry Pi, Arduino, and embedded Linux-based systems. I am familiar with RF and wireless ICs/modules including Semtech SX12 series LoRa devices, Nordic BLE chips, ESP32 wireless modules, Quectel LTE/GPS modules, u-blox GPS modules, RFID reader modules, RF filters, LNAs, PAs, RF switches, baluns, and matching networks. For PCB design, I use Altium Designer, KiCad, EasyEDA, Eagle, and OrCAD I also have experience with enclosure design for RF and embedded products, including plastic and metal enclosures, antenna placement, RF keepout areas, mechanical fit checks, connector positioning, thermal considerations, waterproofing concepts, mounting features, and PCB-to-enclosure integration. I understand that enclosure design can directly affect RF performance, antenna efficiency, heat dissipation, usability, and manufacturability, so I always consider the mechanical structure together with the electronics. I have worked for years on IoT devices, wireless sensors, RFID products, antenna-integrated PCB designs, FPGA boards, digital electronics, embedded controllers, data acquisition systems, and prototype-to-production hardware. System engineering and integration have been important parts of many of my projects, especially where RF, firmware, FPGA, PCB design, and enclosure design must work together reliably. My main strength is not only designing a schematic or PCB, but building complete hardware that works reliably in the real world. I always consider RF performance, signal integrity, grounding, shielding, power stability, EMI/ESD protection, enclosure integration, manufacturability, testing, and long-term reliability from the beginning of the design.

I am a Materials Science Ph.D. and AI/ML consultant specializing in machine learning, industrial AI, materials informatics, chemistry-driven process optimization, and decision-support systems. I help technical teams turn messy experimental, operator, sensor, process, and production data into predictive models, dashboards, and AI workflows that support faster decisions, lower chemical usage, better process control, and measurable operational savings. I have worked directly with CTOs, process engineers, plant operators, project managers, and technical leadership to translate operational problems into deployable AI solutions. My focus is accelerating decision making. What I deliver: • Real-time prediction models for industrial and chemistry-driven processes • Decision-support AI tools for operators, engineers, and managers • Machine learning models for process optimization, quality control, and performance prediction • Transformation of operator logs and process records into clean, model-ready datasets • Exploratory data analysis to identify process drivers, anomalies, and failure patterns • Anomaly detection for sensor, production, experimental, and operator-recorded data • Time-series modeling for process monitoring, forecasting, and live decision support • Tree-based regression and classification models for interpretable industrial prediction • Hierarchical classification workflows for complex scientific and materials datasets • Deployment-ready dashboards and applications for technical users Relevant industrial AI experience: • Built predictive models for real-time process variables, including treatment performance, effluent quality, chemical response, and operational stability. • Developed decision-support workflows that helped operators evaluate process conditions and accelerate treatment decisions. • Converted inconsistent operator logs and process records into structured datasets for machine learning, dashboarding, and deployment. • Created models to support chemical dosing optimization, reducing unnecessary chemical use while maintaining target process outcomes. • Built classification and prediction workflows for complex materials, chemistry, and industrial datasets. • Developed exploratory analytics and anomaly-detection workflows to identify abnormal process behavior and data-quality issues. • Designed model-development pipelines covering data cleaning, feature engineering, model training, evaluation, interpretation, and deployment. • Delivered working applications and dashboards for stakeholders including engineers, managers, operators, and executive leadership. Core expertise: • Industrial AI and machine learning model development • Materials informatics and chemistry-driven process modeling • Exploratory data analysis and process-data diagnostics • Anomaly detection and outlier analysis • Time-series modeling and real-time prediction • Regression, classification, and hierarchical classification • Tree-based modeling, feature importance, and model interpretation • Decision-support dashboard and application development • Scientific data cleaning, visualization, and reporting • End-to-end project execution from raw data to deployed tool Selected project areas: Industrial Process Prediction and Decision-Support AI Developed industrial AI work includes developing machine learning models and operator-facing decision-support tools for real-time process prediction, chemical dosing support, treatment performance monitoring, and process optimization. I converted operator-recorded and real-time process data into structured datasets, predictive models, and user-facing applications that helped operators and engineers make faster treatment, dosing, and process-control decisions. These tools reduced decision time, supported live process monitoring, and identified potential operational savings of $100K–$200K per year through improved chemical use and process control. Materials Informatics and Scientific ML Built predictive models for materials-property estimation, chemistry-performance relationships, and scientific feature engineering. Work includes modeling alloy properties, chemistry-driven performance, and complex experimental datasets. Anomaly Detection and Process Diagnostics Created workflows to identify abnormal sensor behavior, inconsistent operator records, outlier samples, and unusual process conditions.
