Having grown beyond junior responsibilities, this role is expected to deliver production-ready features independently, contribute to technical decisions, handle deployments through our CI\/CD pipeline, and integrate the platform with third-party services such as PayFast and transactional email providers. DUTIES: • Translate product specifications and designs into working, production-ready features across the full stack. • Build and maintain frontend interfaces using React 18, Vite, TailwindCSS, and shadcn\/ui (Radix UI), ensuring accessibility and responsive behaviour. • Develop backend REST API endpoints using Node.js and Express, following established conventions for authentication, validation, and error handling. • Implement client-side state management using TanStack Query and form handling with React Hook Form and Zod validation. • Design and maintain PostgreSQL 16 schemas, write efficient SQL queries using the pg. (node-postgres) driver, and manage database migrations. • Implement data models that balance performance, integrity, and future extensibility. • Ensure backend security through proper use of Helmet, express-rate-limit, and Better Auth session-based authentication ( Only cookies). • Convert UI\/UX designs into pixel-accurate, accessible interfaces using TailwindCSS and Radix UI component primitives. • Implement client-side routing with React Router v6 and add polish through Framer Motion animations where appropriate. • Integrate map functionality using Leaflet and maintain a consistent visual language through the Lucide React icon library. • Build and maintain integrations with PayFast for payment processing, including handling of ITN (Instant Transaction Notification) callbacks and reconciliation. • Implement transactional email flows using NodeMailer (e.g. password reset, account notifications). • Integrate additional third-party APIs as required, ensuring secure credential management and graceful error handling. • Handle file and image uploads via Multer, including validation, storage management, and persistence through named Docker volumes. • Manage container orchestration using Docker Compose and ensure local and staging environments mirror production. • Configure and maintain Caddy as a reverse proxy, including automatic provisioning. • Maintain and improve the CI\/CD pipeline using self-hosted GitHub Actions, including staging deploys triggered on push to main. • Monitor Better Auth cloud dashboard (dash and sentinel plugins) and respond to authentication-related signals. • Diagnose and resolve bugs reported by users, internal stakeholders, or surfaced through monitoring. • Refactor and improve existing code to reduce technical debt and improve maintainability. • Write clear commit messages, meaningful pull request descriptions, and inline documentation where logic is non-obvious. • Ensure security best practices are applied across the stack (input validation, secure cookies, rate limiting, dependency updates). REQUIREMENTS: • Minimum 2 years of professional software development experience. • Demonstrated experience building and maintaining production web applications across the full stack. • Proven track record of shipping features from specification through to deployment. • Experience working in a Git-based collaborative development environment. • Self-motivated learner who keeps up with developments in the JavaScript \/ React \/ Node.js ecosystem. • Reliable, accountable, and proactive in flagging blockers or risks early. • React 18 with hooks and modern functional component patterns. • Vite as a build tool, including environment configuration. • React Router v6 for client-side routing. • TanStack Query for server-state management and caching strategies. • React Hook Form with Zod schemas for type-safe form validation. • Framer Motion for UI animations. • Leaflet for map-based interfaces. • Node.js with Express framework — routing, middleware, and REST API design. • PostgreSQL 16 and SQL fluency, including the pg.
