📋 Description

• Design and implement backend services and APIs using Node.js and TypeScript. • Develop scalable architectures to support integrations with third-party APIs (e.g., payment gateways, third-party delivery systems, CRMs). • Own the end-to-end development of backend components — from design to deployment. • Collaborate directly with frontend engineers, product managers, and DevOps. • Guide the technical strategy around API design, versioning, and documentation. • Ensure reliability, observability, and performance of all backend systems. • Manage authentication/authorization, security, and data validation across integrations. • Interface with U.S.-based clients to understand technical needs and deliver quality solutions. • Contribute to internal best practices around code quality, testing, and CI/CD.
