Kevin Hartmann

Senior Software Developer @ Centre for Digital Therapeutics

About

With multiple years of professional programming experience, I bring a strong focus on backend development, microservices, and healthcare IT. At Centre for Digital Therapeutics, I contributed to server back-end enhancements using Java and Spring Boot, while collaborating with cross-functional teams to resolve critical issues and implement solutions. Previous roles at Smile Digital Health and Ontario Institute for Cancer Research expanded my expertise in health record management systems, HL7 FHIR standards, and cloud-based microservice deployments. Passionate about creating impactful solutions, I aim to leverage my technical skills to drive innovation and efficiency in software systems.

Designed and implemented all the software for a dedicated hardware device. Evaluated Java, Python, Haskell, Forth, Lua (Luajit), Ada(Gnat), Squirrel, Julia, and Nim as potential implementation languages Wrote TCP clients to connect to remote servers (in Java) Re-wrote code from Java to Python, cutting the total source code size in half Implemented Bluetooth libraries for Java and Python When asked to make our code work like Android Bluetooth library function, downloaded the Android operating system's code, examined the Java and C code, and discovered that it was the Android documentation that was at fault. Wrote a framebuffer graphics library to ensure maximum compatibility across display hardware Wrote C. libraries for Java and Mysql Reduced ARM Linux installation size from 2GB to 20 MB. Remote update times and cellular bandwidth usage were thus 100 times smaller. Customized u-Boot boot loader (using C) to enable “watchdog timer” hardware feature. Made Linux Device Tree (a description of the circuit board hardware) work when even the circuit board manufacturer couldn't Designed robust software for automatic remote updates. Even if a bad update erased every file or killed every process on the system, the system recovered automatically.
