As an IT and networking enthusiast, I am intrigued about all aspects of computer networking and network engineering and work full time as a network engineer.

Currently, in my role as a System & Network Engineer at cldin, I am responsible for managing and maintaining the network infrastructure and implementing new technologies to support business operations.

I am also grateful to have had the opportunity to share some of my knowledge and insights through my writing via the APNIC blog for which I was included in their Top 3 ‘How to’ posts in 2021 with my article “Edge router and BNG optimization”. Also found it pretty cool to have had my IPv6/NDP article covered by Packet Pushers in this podcast.

In addition to my full-time job, I also selectively offer consultancy services to ISPs around the world, helping them implement best practices and optimise their configurations.

In my spare time, I enjoy sharing my knowledge and insights with others, and I publish a variety of networking-related content on this site for Telcos and ISPs. I also enjoy photography and music, and I am the proud owner of my own network (AS149794).

I am always open to new opportunities and connections with those who share my passion for computer networking.

I have worked with the following:
