Founder and Engineering Lead at Silicon Witchery, where we develop AI-powered wireless modules and provide expert consulting services for IoT product development. Our flagship products include the S1 Module, a compact BLE solution for wearables, and the S2 Module - a complete LTE-M solution with global connectivity, remote programming, and AI-powered data analysis. I lead our engineering team and company operations, specializing in system architecture, hardware design, and RF engineering (BLE, LTE-M, NB-IoT). Our consulting services help businesses accelerate their IoT product development, from concept to production, with expertise in low-power embedded systems and AI integration.

Co-founder and Hardware Lead at Brilliant Labs, where we developed smart glasses that redefined industry standards for wearable computing. Our product featured unprecedented integration of display, camera, and microphone systems, powered by an ARM microcontroller and custom FPGA architecture. The innovation earned coverage in Forbes, The Verge, and TechCrunch, establishing new benchmarks for consumer wearable technology. I led the hardware design and firmware development team, creating a complete embedded solution that included custom imaging pipelines, codecs, and graphics IP running on the FPGA. This achievement demonstrated how highly integrated consumer electronics could deliver sophisticated functionality while maintaining a sleek, wearable design.

Hardware and Firmware Lead at Turnpike Group. We created smartwatches for football fans, featuring live game metrics and interactive features for fan engagement. I led the hardware design, firmware development, and smartwatch user experience. The role gave me extensive experience with Asia based manufacturing and supply chain.

Application Engineer at SiLabs. I supported customer projects using our Zigbee products, working closely with the Zigbee specifications team. My role focused on both engineering, as well as compliance for smart home and smart energy applications. Notable customers included Bosch, IKEA, Siemens, and British Gas, helping them integrate wireless connectivity into their products.

Research Engineer at Bristol Robotics Lab. As part of my master's studies, I developed control systems hardware for automotive and space applications, focusing on practical implementation of robotic systems.

Student Researcher at University of Bristol. I helped develop a remote control car platform for the Computer Science and Engineering lab, featuring four independent motors for torque vectoring algorithms. The system included gyroscopes for steering correction and traction control, with a fuzzy logic control system I developed. The 1kW vehicle achieved 70kph with precise control, while streaming real-time telemetry to a MATLAB interface for performance analysis and simulation comparison.
