I was attracted to NetCraftsmen by the reputation of excellence shared by the company. I remained because of the supportive and co-operative culture that I found there. Being a part of NetCraftsmen puts you in conference with some of the best brains in the networking industry and offers you a chance to develop your own skills in a dynamic and wide-ranging environment.


I like working on challenging engineering solutions and developing strong technical teams which customers rely on to support and guide them in crafting business solutions.I especially like to nurture ambitious engineers and provide them the tools and opportunities to meet their goals.


I like to fix things and feel like there is not an appliance, motor or machine that is beyond repair (sometimes to the despair of those who would rather buy new). I love the outdoors, large bodies of warm water, and love to eat and cook exotic foods; the spicier the better.
