Eliakim ("Eli") Willner is a high-tech professional specializing in electronic publishing and general outsourcing. He is also an avid student of Jewish philosophy, ethics and law, and his writings reflect both aspects of his persona.

Eli is currently presenting a series of seminars on the Maharal's "Nesiv HaAvodah" and the Jewish philosophy of prayer; he is also working on an annotated translation of that work, of "Shev Shmaitso" by Rabbi Aryeh Leib HaKohen Heller, which focuses on principles of Jewish legal exegesis, and of "Pachad Yitzchok", a work of Jewish philosophy centered around Jewish holidays by Rabbi Yitzchok Hutner.

He frequently publishes articles on topics of Jewish and/or technical interest in a variety of publications.
