Integrate and test Firebase backend solutions (Firestore for client databases, Authentication, or hosting environment). Implement responsive layouts using BEM methodology for absolute pixel-perfect viewports. Configure reliable automated notifications or contact forms (e.g., via EmailJS or internal triggers). Requirements: Strong portfolio featuring clean, high-performance SPAs. Deep understanding of Vanilla JS and modern CSS tricks. Ability to deliver fully responsive, production-ready code.
