Ogunseitan earned his Degree in General Art with Distinction from the School of Art, Design and Printing at Yaba College of Technology in Lagos. He later specialised in digital painting and three-dimensional design at Sporedust Animation Studios — Nigeria’s first formal animation studio, where he was among the early founding team — and worked as a comic colourist with Pedacomic, widely regarded as the country’s leading comic book publisher in 2020.

He played a central role in strengthening creative infrastructure across West Africa, founding Drippcity NG Creative Space, one of the largest independent creative hubs in the region, established to provide training and clear career pathways for young artists. In 2017 he launched the Art Tour Initiative, bringing structured art education and workshops directly into schools and rural communities.

In 2018 he co-founded Kopas Art Jamboree, designed to open professional pathways into the arts sector — linking trainees to gallery placements, exhibition opportunities and studio roles, and tackling youth unemployment by delivering work-ready training and equipping people to take up jobs, freelance work or launch creative enterprises. The initiative gained official recognition from Nigeria’s federal and state governments and was honoured with the Impact Organisation Award in 2022.

From 2018 onwards he worked closely with leading arts institutions and galleries including Iwalewa Gallery, Mydrim Gallery, Alliance Française and Kokopelli Africa Gallery, securing exhibition opportunities and professional placements for graduates and trainees from his programmes.

Shortly after relocating to the UK in 2023 with his wife, he began volunteering with AfricanWelsh News, facilitating workshops and art education sessions at Loudon Square in Cardiff to support new arrivals integrating into local systems and culture. Guided by the belief that art belongs to everyone and should never be confined within buildings, and finding access to formal gallery spaces limited, he created a distinctive method combining hand-painted textiles and clothing design with live public performance — first in Cardiff city centre and later across central London. One such performance was acknowledged by Liara Barusi, founder of Jukebox Collective, leading to his appointment within the core team, where he delivers workshops and contributes to the development of major museum and film projects.

His work has since been shown at key national venues including the National Portrait Gallery in London, Wales Millennium Centre in Cardiff, and the National Library of Wales at Aberystwyth, where examples are held in the permanent collection, as well as Firstsite Museum in Colchester and numerous galleries and public spaces across Cardiff and London. His award-winning contribution to Portrait of Britain 2024–25 formed part of the series Studio CF: Colour Theory, created alongside photographer Michael Tiedke and displayed nationwide on JCDecaux billboards.

His solo exhibition The Art of Fashion (2025) brought together digital work, printed textiles and live performance centred on participatory storytelling, community and collaboration — featuring his past and present projects and explaining the connections between his art and design practices. He worked with creative photographer Taiye Omokore on Dyfodol Du – Portrait & Power, commissioned by the National Library of Wales and now preserved within its permanent holdings, and exhibited alongside artists represented by KEI London Art Agency in a 2024 group show featuring Dangerosa and other established British practitioners. In 2025 he received funding through UA in the UK from the Mayor of London for an exhibition for designers and artists in Westminster, and in 2024 delivered commissioned work and performances for Butetown Carnival at Wales Millennium Centre.

Working with Jukebox Collective and Sustainable Studios Cardiff, he serves as Lead Facilitator, designing and delivering workshops across digital painting, storyboarding, mood-board development, textile methods and illustration, alongside applied skills in industry-standard software such as Procreate and Photoshop.

In 2024 he established Art in the Park UK in partnership with Cathays Youth Community Centre in Cardiff — a charity-led initiative bringing free creative learning to young people and individuals with additional learning needs, transforming public parks into safe spaces for building skills and confidence.

He currently holds the post of Creative Wellbeing Lead with Essex County Council, delivering arts-based interventions in hospitals, care homes and community centres to support mental health and recovery, and serves as Volunteer Curatorial and Gallery Assistant at Firstsite Museum in Colchester, an institution within Arts Council England’s National Portfolio.
