Embedded Systems & Robotics I design and build embedded and robotic systems with a strong emphasis on control, sensing, and real-world reliability. My experience includes analog and digital electronics such as op-amp–based square wave generators and voltage stabilizer circuits, as well as advanced robotic platforms. I have developed a self-balancing robot using MPU6050 sensor fusion, a PID control algorithm, and H-bridge motor drivers, and worked on mobile robotics projects including autonomous mobile robots involving chassis design, SLAM, and mapping, as well as Arduino- and Python-based automated guided vehicles. I have also built a weight-based automatic IV bag level detection and shut-off system using load cells and servo actuation, contributed to internal R&D such as the Melody AI Robot (a “mother” AI framework at Kadosh coordinating other AI modules), and designed wearable electronics including the Ensee smartband PCB. Mechanical Design, CAD/CAM & Digital Manufacturing I specialize in parametric mechanical design and design-for-manufacturing workflows using FreeCAD and SolidWorks, producing clean, editable models and fabrication-ready outputs. My work spans functional and conceptual designs such as heliostats, enclosures for activity monitors and IV bag gauges, micropump concepts, and a complex airship hull. I have delivered highly parametric projects including an articulated box system and an ergonomic mouse, as well as product-oriented designs like fishing tackle box systems, AR-15 handguards with integrated sling-lock concepts, bathroom fixtures, jewelry, figurines, and extensive STL modification work (e.g., Raspberry Pi and enclosure adaptations). I also have hands-on experience with cabinet manufacturing and assembly, CNC machining across a range of materials, and edgebanding processes, bridging digital design with physical production. Manufacturing Software & CNC Tooling I work with Mozaik for cabinet design and manufacturing workflows, Aspire and VCarve for CNC toolpath creation, and LightBurn for laser cutting and engraving operations. These tools are used to translate CAD designs into accurate, production-ready machining and cutting processes. Programming, Software & Robotics Frameworks My programming experience supports both low-level firmware and higher-level system development. I work with Arduino for embedded firmware, Python for robotics control and mapping tasks, ROS for robotic workflows, C for low-level software development, and Bash scripting for system tasks. I also have experience with Django for backend engineering and WordPress for delivering supporting web interfaces or project sites when required. Technical Documentation & Communication I produce clear, structured technical documentation to support engineering, manufacturing, and validation workflows. This includes academic-style technical reports, manufacturing documents, and DFM-oriented deliverables. I also create supporting visual and brand assets using tools such as Photoshop, Illustrator, Canva, and related design platforms to ensure designs and systems are communicated effectively to technical and non-technical stakeholders.
