About Me

I am Hossain Md Sahadat, a connectivity and infotainment test engineer hailing from Bangladesh. From an early age, I was captivated by the wonders of technology and its transformative power. Fuelled by this passion, I embarked on a remarkable journey that has taken me to the forefront of the tech industry, where I strive to push boundaries and unlock the potential of cutting-edge advancements.

My educational voyage began in Bangladesh, where I completed my elementary and high school education. Recognizing my inclination towards computers and programming, I chose to pursue a degree in Computer Science and Engineering at Brac University. During my time there, I delved deep into the intricacies of Java programming, data structures and algorithms, mathematics, databases, and automata theory. As I sharpened my skills in Java, I became fascinated by the world of Android app development. This curiosity led me to participate in a mobile app development trainee program sponsored by the ICT Ministry of Bangladesh, where I gained valuable insights and practical experience in building innovative mobile applications.

Seeking to broaden my horizons and explore new frontiers, I embarked on a remarkable adventure to South Korea as a transfer student at Sejong University. It was here that I truly immersed myself in the realm of advanced technology. From studying computer architecture and mobile programming to web programming, image processing, artificial intelligence, and human-computer interaction, I absorbed a wealth of knowledge that laid a solid foundation for my future endeavors.

While still pursuing my studies, I began my professional journey as a part-time social media marketer at 'joy2korea' in Seoul. This role allowed me to delve into the dynamic world of digital marketing and gain hands-on experience in engaging with diverse audiences. Eager to expand my skill set further, I joined 'Vision ps gmbh' as a measurement engineer, where I had the privilege of collaborating with leading technology companies like Huawei and Umlaut. Immersed in the realm of 5G technology, I focused on mobile network benchmark testing and device performance evaluation, honing my technical expertise and understanding of the latest advancements.

Driven by an insatiable thirst for knowledge, I transitioned to the position of a device test engineer at 'Vision ps gmbh.' During this period, I collaborated with esteemed companies such as Umlaut and Wistron, specializing in 5G wavelength testing. The experience allowed me to gain invaluable insights into cutting-edge technologies and further expand my skill set.

In 2022, I embarked on an exciting opportunity as a telematics test engineer with Umlaut, working on the Ford global connectivity project. This endeavor gave me the privilege of contributing to the future of automotive connectivity. From flashing automotive modules to testing vehicle connectivity and meticulously examining the FordPass app, I played a vital role in enhancing the driving experience for Ford customers worldwide.

Presently, I serve as a connectivity and infotainment test engineer at AnD Convergence, where I work closely with AUDI Korea. In this role, I passionately test and refine the vehicle connectivity and infotainment systems, ensuring that the latest technologies are seamlessly integrated into the driving experience. It is a fulfilling endeavor that allows me to remain at the forefront of automotive innovation.

Beyond my professional pursuits, I am an avid explorer and seeker of new experiences. I find solace in traveling, hiking, and cycling, as they offer me a chance to recharge and gain new perspectives. Additionally, I cherish the opportunity to immerse myself in diverse cultures and meet inspiring individuals along the way.

As an advocate for the future of work and education, I actively share my ideas and observations on platforms such as Medium or LinkedIn . I invite others to connect with me, fostering meaningful discussions and collaborations to shape a brighter tomorrow.
