Lumuli is the founder and current president and CEO of Multivariable Systems Technologies. He was born in a small village in Western Province of Kenya, and grew up on a 15-acre farm where his family raised crops and animals to support themselves and fund their education. Lumuli went on to study at Kenyatta University in Nairobi before volunteering for non-profit organizations at Nairobi University and Lewis in England..

After relocating to the U.S., Lumuli worked for nearly a decade as an electrical engineer and in various capacities in the  locomotive manufacturing plant and power companies in Idaho and Delaware. These experiences informed his need to establish an electrical engineering company that draws its strength from lived experiences and best practices in business by putting people first. He went on to establish Multivariable Systems Technology in 2017, now a leading government contracting company in Idaho performing multi-million dollar electrical and technical projects in various agencies of the United States. Lumuli has not forgotten his humble upbringing and regularly connects with people on similar life journeys.
