Product Manager specializing in mobile development and UX
I design and build intelligent, user-centric mobile experiences. Over the past year, I’ve developed three Flutter applications integrating Bluetooth to control embedded devices—including one currently in use on high-profile film sets for professional light control. I specialize in product strategy, UX design, and mobile architecture, helping teams turn ideas into market-ready applications. I’ve personally designed every app I’ve built in Figma, ensuring a seamless connection between user experience and technical execution. Recent Work & Experience: Scavenger Hunt Platform – Founder & lead developer of an interactive location-based platform that blends exploration with business engagement. Mobile & Product Consultant – Helping teams refine their product vision, design intuitive experiences, and scale development in Flutter. Industry-Leading Pharmacy Consumer Platform – Managed the product backlog and roadmap, shaping the experience for thousands of users. Software as a Medical Device (SaMD) – Led development at electronRx, defining, architecting, and launching a vitals monitoring app through full SDLC into clinical research. Casino Technology – Built industry-leading hardware & software, now deployed across Las Vegas Strip casinos. Beyond development, I thrive on growing teams and shaping product direction. At electronRx, I scaled our team from 2 to 8 developers while serving as Scrum Master, optimizing sprint efficiency and cross-functional collaboration. I’m always open to conversations about product design, Flutter development, and innovative mobile experiences. Let’s connect.

Graduate Software Engineer

Cambridge Logic LtdSep 2019 - Mar 2022 • 2 yrs 7 mosProgressing from my internship I work exclusively on Arm processors for casino equipment and specialist film lighting. Configuring control boards to perform a wide variety of tasks using communication protocols and other features. I have worked with DMX, RS485, USB, I2C, EEPROM, ADC/DAC, PWM, GPIO, Ethernet and recently a touchscreen display. I have also optimised and improved algorithms for older projects for newer uses. My final project was as the sole developer on a flutter application to act as an interface for a new way to bet on roulette. Constant communication with a server using sockets in two different ways, due to webapp and android differences, it provided live data updates to keep the game running. It used state machines and GetX State Management. Creating reusable, efficient and clean code is a primary goal for every project.
