Aisha Oyegunle

I’m a product engineer with 7+ years of experience building payments, internal platforms, and user-facing products. I work across product and engineering to turn customer needs, commercial goals, and operational constraints into software that is useful, reliable, and built to last.

My experience spans fintech, civic technology, proptech, and service delivery, including work at Flutterwave (opens in new tab) and as Lead Product Engineer at Archivi.ng (opens in new tab). I’ve helped expand checkout products into new markets, currencies, and payment methods, and built shared infrastructure, research tools, and operational systems, with equal attention to the people using the product and the engineers responsible for what comes next.

Working on something worth building well?

I’m available for senior product and software engineering roles, and open to selective consulting on products and systems where thoughtful engineering can make a meaningful difference.
