Seeman began his career in the Tamil film industry during the mid-1990s, directing movies such as Panchalankurichi (1996) and Veeranadai (2000). His films often carried themes of Tamil identity and social justice, which later shaped his political ideology. By the late 2000s, he transitioned fully into politics, founding the Naam Tamilar Iyakkam before establishing the Naam Tamilar Katchi in 2010.
As a politician, Seeman has been a vocal supporter of Tamil nationalism, often making controversial statements regarding Indian social and political issues. He has campaigned extensively across Tamil Nadu, positioning NTK as a party focused on Tamil rights, environmental protection, and regional autonomy. Despite criticism, he remains a popular figure among sections of Tamil youth and activists.
