Hi, my name is

Mohammad Karim

As a full-stack developer with over 3 years of experience, I bring a core expertise in developing robust web applications and cross-platform mobile solutions, underpinned by exceptional critical thinking skills that allow me to tackle any challenge with a proactive and solution-oriented mindset.

With a Bachelor's degree from UTS, my full-stack development journey continues at Mirk following an internship. I possess a proven ability to solve complex programming challenges, demonstrated through my work on various projects and as a sole trader at Quormotion. There, I independently developed applications like Brain Twist and delivered key client solutions, including a Bulk SMS Sender to streamline customer communication and an Invoice Processor for efficiency.

Bulk SMS Sender App

Built a custom mobile app for a client to send bulk SMS messages efficiently. Collaborated closely with the client to understand their workflow and specific needs, delivering a tailored solution that streamlined communication and improved productivity. Used Kotlin natively to set the app as the default SMS handler on Android devices, ensuring seamless message delivery and control.
