Available to hire
Hi, I’m Grant Marthinus, a Senior Software Developer with a strong foundation in mechanical engineering and automation engineering. I enjoy building scalable web applications and intelligent automation solutions, using React, Next.js, Node.js, and Python, while leveraging cloud services and scalable databases. I’m comfortable designing both front-end and back-end architectures, as well as working with hardware integration and manufacturing environments. I’m passionate about mentoring teammates, refining requirements into clear user stories, and exploring new technologies to drive value.
I’m committed to collaborating with clients and teams to achieve ambitious outcomes, while keeping quality, reliability, and performance at the forefront. When I’m not coding, I’m learning new tools, sharing knowledge, and contributing to innovative projects in manufacturing, cloud, and IT services.
