01 // company
A registered Indian company with a long record.
ABCOM was incorporated with the Registrar of Companies, Mumbai, on 18 August 1997, and has been led by its founder ever since. That continuity is something we're proud of: the same people who started the company still answer for its work.
Company details are a matter of public record and can be verified on the Ministry of Corporate Affairs (MCA) portal using the CIN.

Prof. (Dr.) Poornachandra Sarang
Founder & Director, ABCOM Information Systems
Dr. Sarang founded ABCOM in 1997 and has led it as Director since its incorporation. He is an internationally known IT consultant and author whose professional career spans more than three decades, and whose books on emerging technologies have been published by Springer, Apress, McGraw-Hill (Oracle Press), Packt, Wrox and PHI Learning.
Alongside industry work he has stayed close to teaching. He has been a Visiting Professor of Computer Engineering at the University of Notre Dame, USA, and is adjunct faculty in the Department of Computer Science, University of Mumbai, where he teaches postgraduate courses, guides project work and supervises Ph.D. students. His research interests include distributed systems, mobile computing and algorithm development.
His writing has followed the industry's arc — from Java, XML, Apache and .NET in the early 2000s, through service-oriented architecture and BPEL, to neural networks, data science and blockchain interoperability today. Through ABCOM Press he has also published English and Hindi commentaries on the Gyaneshwari.
