By 1995, she had dived deep into the digital world, working as a SysOp for Realm of Mirage BBS in Fair Lawn, NJ. Her love for the field took her to Rensselaer Polytechnic for Computer Science and later to Stevens Institute for Applied Mathematics. Now with over 20 years of experience, Marian remains dedicated to the intricate art of coding and the ever-evolving world of technology.
