Ajape Rasaq

Backend engineer focused on financial systems, high-concurrency transaction processing, and API reliability. Designs and builds production-grade systems with deliberate attention to transaction integrity, idempotency, double-entry ledger design, and system observability. Approaches backend engineering with a senior-level design-first methodology — mapping failure modes, fallback strategies, and compliance constraints before writing code.

Currently building FinCore, a CBN-aware payment infrastructure platform modelled on Paystack/Stripe architecture.
