Software Engineer at Obotan PLC building BNPL checkout and commerce experiences.

Ghana

Message

At Obotan PLC, I'm engineering a multi-vendor BNPL cart and checkout flow that preserves cart state across varying network conditions. I also redesigned Obotan Shop and Product Details to improve product discovery and the purchase journey.

At Syka, I architected a fintech escrow API with sub-200ms response times and led engineering across cross-border escrow and payments workflows. At VerifiBuy (formerly KudiGo), I led development of a social commerce escrow interface that cut development time by 40%.

I also built qVouch, a multi-tenant customer review platform with AI-assisted reply drafting, and LearnSor AI, which turns uploaded documents into source-grounded study notes. I’m a Software Engineering Career Mentor and have mentored peers pursuing software engineering careers.
