About Me

Hello! I am Md. Anisur Rahman, an Electronics Engineering professional with a strong passion for circuit design, simulation, and practical electronics education. My journey in this field is rooted in a deep interest in understanding how electronic components behave and how complete systems function through precise circuit design and analysis.

I have completed my Professional Diploma in Electronics Engineering from Online University of UK in 2018, which provided me with Electronics foundation in practical electronics. Over the years, I have focused on applying this knowledge through real-world circuit testing and virtual simulation environments.

I am actively involved with the DCACLab Circuit Simulator as a Circuit Analyst (Teacher), Technical Content Writer, and Forum Moderator, where I contribute by designing circuits, analyzing component performance, suggesting new component ideas, and helping to improve simulation accuracy for educational use.

My goal is to enhance electronics learning through realistic simulations that bridge the gap between theory and real hardware. I strive to make complex electronic concepts simple, practical, and engaging for students, teachers, and electronics enthusiasts.
