I come from an electronics background with limited programming knowledge, and despite securing a job in the software industry, I found myself in a support project. Struggling to clear development team interviews due to a lack of programming language expertise, I was fortunate to get guidance from my better half, Heartin.

Heartin took it upon himself to teach me Java from the ground up. His training and mentoring was invaluable as he patiently led me through the intricacies of programming, ensuring I understood each concept thoroughly. His teaching methodology, practical questions, and unwavering support played a pivotal role in shaping my career as a programmer. 

I not only gained the necessary skills but also successfully cracked development team interviews. Today, I find myself leading a technical development team, a feat that seemed unattainable before.

I first met Heartin during my Engineering days, when I struggled in a computer science course due to a lack of foundational knowledge. Recognizing the gap, Heartin offered to teach non-CS students, transforming my performance from just passing to a remarkable 98%. Heartin's teaching style was about filling gaps and instilling a profound comprehension of the subject matter.

Fast forward 17 years. Having dedicated over 16 years to legacy technologies, I needed to transition into the latest industry trends. The technology landscape had evolved significantly during my hiatus, leaving me unsure of where and how to begin my Cloud journey. As a trusted friend, I turned to Heartin for guidance. Heartin not only provided a clear learning path but actively assisted me in navigating the complex world of Cloud computing.

Heartin is more than a teacher; he's a dedicated guide ensuring success in the dynamic tech landscape. His mentorship extends beyond technical insights, embodying a commitment to his students' success. I wholeheartedly recommend Heartin to anyone seeking not just a teacher but a mentor who truly cares about their journey in technology
