Design and implement POS solutions with React Native for cross-platform mobile interfaces and Node.js (or similar) for backend services. Create and manage RESTful APIs, GraphQL endpoints, and ensure secure, efficient data flow between client and server.
Architect and optimize React Native applications with state management using Redux or MobX, hooks, and context API for data flow. Build native modules and maintain performance across iOS and Android platforms.
Develop and manage backend services that support the POS platform, using Node.js, Express, and integrating with databases like MongoDB or PostgreSQL. Ensure data synchronisation, transactional consistency, and support for real-time updates in POS operations.
Serve as a technical authority in client interactions, collaborating with stakeholders to understand requirements, gather feature requests, and translate them into full-stack solutions that support business goals.
Collaborate with sales teams to provide technical guidance during the sales process, highlighting scalability, reliability, and integration strengths of our POS solutions. Support product development by relaying client feedback and translating it into actionable engineering features.
Lead client support efforts to resolve frontend and backend issues, ensuring high performance and client satisfaction. Provide technical recommendations for system optimization and best practices.
Connect client needs with internal product teams, prioritise feature enhancements, and contribute insights on POS industry standards to inform engineering efforts.
