Prince Emmanuel

Prince Emmanuel Software engineer -- Lagos, Nigeria LinkedIn Github Summary I’m a full-stack developer who believes that building a product—especially a fintech solution—goes beyond just shipping code to production. I focus on enhancing security at every level, ensuring systems are not only functional but also resilient against threats. I specialize in React Node.js and Go on the backend, with experience in frontend technologies to deliver seamless user experiences. I continuously work to scale system security across the stack, ensuring both backend and frontend components are robust and secure. With experience in building and scaling fintech products—from wallets and payment gateways to banking systems—I bring a deep understanding of both architecture and security. While fintech is my core expertise, I’m open to working across any sector where robust, scalable full-stack solutions are needed.
