About

I am Sathish Mariappan, the Founder and Director of Promon. My career has been deeply rooted in the telecommunications sector, spanning over two decades of experience in BSS and OSS systems. From my early days as an engineer at TCS to my time as a Solution Architect at Openet and a consultant for Tele Post, I have focused on the complexities of billing, mediation, and charging systems. Today, I lead a managed services firm dedicated to helping European telecom operators modernize their stacks through microservices and DevOps practices. I am passionate about bridging the gap between traditional telecom infrastructure and modern software engineering. I am always open to connecting with others in the industry to discuss technical challenges, architecture, and potential collaborations.
