Top SchoolTosin Afolabi is a product-focused mobile engineer with 11 years of experience building delightful iOS experiences and shipping consumer and developer-facing features at companies like Slack, Stripe, Cash App, Anthropic, and Harvey. He blends pragmatic engineering with product sense—treating code as a means to build useful, polished products rather than an end in itself. At Slack he contributed to notable open-source iOS libraries (PanModal, SlackTextViewController), fixing subtle gesture and presentation bugs and adding package manager support that improved developer ergonomics. His recent roles span payments, consumer finance, and safe AI, reflecting an ability to move between high-trust platforms and experimental teams. Based in New York, he brings deep iOS expertise (gesture/animation, networking, offline sync) plus a habit of shipping small, high-impact fixes that improve UX for both users and integrators.
