Contribute to the design and development of backend APIs to support frontend functionality, ensuring efficient data flow and integration with application features. Gain deep insights into the product, customer needs, and competitors to enhance user experience and align features with creator and learner expectations. Partner with designers, product managers, and backend engineers to deliver high-quality, cohesive user experiences across web and mobile platforms. Keep up with the latest frontend technologies (e.g., WebAssembly, modern JavaScript frameworks) and advocate for tech stack improvements to enhance performance and developer productivity. Utilize AI-driven tools and frameworks to enhance frontend experiences, such as personalizing user interfaces, optimizing content delivery, or automating UI testing and performance analysis.
