Tobi Arogunmati
I manage strategic projects and lead cross functional teams through enterprise transformation, from strategy and product thinking to clean delivery. With a strong grasp of the startup and technology landscape, I thrive at the intersection of innovation, strategy, and execution.
Consulting discipline,
banking-floor grounding.
I'm a technology advisory consultant with 9 years' professional experience, including 5 years driving digital transformation across financial institutions at KPMG Nigeria, where I've progressed from Experienced Analyst to Assistant Manager.
I've delivered core banking (Oracle FLEXCUBE, Temenos Transact), treasury (Calypso), lending, and trade platforms across 5 Nigerian and Central African financial institutions — from requirements and vendor selection through go-live and stabilisation. Along the way I've led the integration of 200+ enterprise applications and directed system integrators and OEM selection on programmes totalling $10M+, advising stakeholders from project teams to board level.
What sets my work apart is the combination of consulting delivery discipline with hands-on banking domain grounding from my years in corporate banking at GTBank — I've sat on both sides of the table, so I speak both languages fluently.
