01 - About

Engineering at
fintech scale.

I'm Andrew, a Full Stack Product Engineer who has spent 6+ years building fintech infrastructure that millions of Nigerians depend on daily. Currently at Interswitch Group, Nigeria's largest payment network.

I've architected high-availability systems across Interswitch Group, Access Bank (50M+ customers), and Africa Prudential — solving hard problems in real-time payment processing, distributed state management, and performance under load. I own entire frontend architectures, design systems, and engineering standards — not just features.

I practice AI-native product development: I've built production LLM pipelines with Claude, designed AI-assisted financial workflows, and integrate generative AI into product UX decisions — not just API calls. I hold certifications from Anthropic, OpenAI, and Oracle, and founded Steward, a React Native finance app with Claude-powered AI reporting.
