I worked as a freelance software engineer for Competition Electronics, a company that manufactures precision timers and other products for the shooting sports industry. I worked on a variety of projects for them, including several mobile apps for iOS and Android, a desktop app for Windows and macOS, and their website.
Digital Link
Competition Electronics engaged my expertise to develop a sophisticated mobile app for their Digital Link and ProChrono DLX projects. The ProChrono DLX, a Bluetooth-enabled device, is designed to accurately measure projectile velocities, offering users the ability to monitor and track this data in real-time via the companion app.
Currently, the app is undergoing a comprehensive overhaul using TypeScript and React Native, incorporating numerous custom native modules and leveraging the Expo toolset to ensure a seamless and high-performance experience for users across platforms.
Digital Link Highlights ⚡
- Wrote native iOS (Objective C / Swift) and Android apps (Java / Kotlin) for communicating with the Digital Link device.
- Wrote TypeScript based desktop app (Windows / Mac) using Nw.js for communicating with the Digital Link device via serial port.
- Continuing to support Digital Link app with software updates and hardware support.
ProTimer
Competition Electronics engaged my expertise to develop the custom firmware for their ProTimer BT and ProTimer devices. Tasked with optimizing efficiency and size, the firmware was designed to operate on a low-power microcontroller while maintaining the ability to communicate seamlessly with the mobile app via Bluetooth Low Energy.
In addition to the firmware, a complementary mobile app was created to enable users to interact with the device effortlessly. The app was developed using React Native, incorporating a custom native module to implement the Bluetooth connection, resulting in a streamlined and user-friendly experience.
ProTimer Highlights ⚡
- Took over and rewrote firmware for ProTimer device with Competition Electronics’ first bootloader allowing for OTA firmware updates.
- Wrote the PT Link app for iOS and Android using React Native and TypeScript for communicating with the ProTimer device.
- Continuing to support PT Link app with software updates and hardware support.
