About

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.

  In my short time at Healthera I coordinated multiple releases across 3 different platforms for their major product as well as a further release on an internal product. Working with UX, Engineering and QA to ensure a successful delivery. I combatted issues with conversion and delivery methods and reworked the Jira to focus on a more feature first sprint method and integrated these quickly into our release plan within just a few weeks of work.

• Technical Product Lead · electronRx2022-10-01 – 2024-02-01

  - Took responsibility of efficiently organising the full design specification of our vitals metric application. This came with coordinating a complete software architecture redesign and a UX overhaul following the completion of the architecture solution. - Became a core member of the senior management team and the initial source of answers with regards to the continued development of our primary product, an API for using smartphone and other widely accessible camera technology to capture our core vitals (Heart Rate, Respiratory Rate, etc) - Oversee the direction of multiple projects under our products label. Planning our product roadmap taking us into both the clinically validated medical device market and the wellness space. - Worked under strict ISO13485 standards when developing a Class 1a with Measuring UKCA device with steps towards a class 2a medical device to be used globally. - Taken on both the technical lead scrum master and product owner role in our agile methodology. Coordinating with my team and training them on best practices whilst determining time scales for feature development and how this can impact our priorities with regards to what our stakeholders require. - Becoming a point of contact for external stakeholders to explain and discuss our product to a higher standard of technical level that is still understandable from someone outside the technical space. - Most importantly, I have been a key innovator during the lifecycle of our product. Constantly listening and assessing what we can provide and how that can fit into the market, all the while considering the regulatory impact that could have on the business and whether some ideas are better than others.

• Graduate Software Engineer · Cambridge Logic Ltd2019-09-01 – 2022-03-01

  Progressing 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.

• Software Engineer Intern · Cambridge Logic Ltd2018-07-01 – 2018-08-01

  A 6-week internship introducing me to programming on ARM processors and a Raspberry Pi. My primary project was to create a poker chip counter using image processing techniques in C. This project included TCP communications, taking stills from a video feed and working with ADC readings.
