Alva Solomon started his career as a proof reader for the privately owned Stabroek News daily newspaper in Guyana. Since then he has covered a number of beats including environmental issues, parliamentary matters, crime, tourism, travel writing, cultural issues, the oil and gas sector daily beats in the city and agriculture. He worked for the state newspaper , the Guyana Chronicle, between 2015-2020 and during that time he was promoted to the post of online editor. Currently, he is a freelance journalist and he has written stories as a freelancer for the non-profit Mongabay as well as the Caribbean Investigative Journalism Network. Locally, he writes feature articles for the Guyana Times daily newspaper. In 2020 he received a National Geographic Grant to write COVID-19 related articles.

Alva specialises in investigative journalism and he has a passion for writing about environmental issues, particularly those relative to indigenous communities and remote villages in his homeland. His article "In Guyana, saving an indigenous language from dying out with its last known speakers" which was published by Mongabay in December 2021, explored the revival efforts by villagers to save the Carib language at a village. He is most proud of that article since he garnered a lot of intricate knowledge from the villagers, including the elders on their culture and traditional beliefs. 

In 2015, he won a prize in the Godfrey Chin Prize for Literature offered by the Guyana Cultural Association of New York as well as health journalism awards offered by the Pan American Health Organisation (PAHO). He was selected to participate in a number of overseas forums including the inaugural Planetary Health Alliance forum at Harvard Medical School in 2017 where he managed to gain much experience and knowledge as part of his knowledge of science, environmental and health issues.
