As the lead web developer, I embarked on the ambitious endeavor of building WithSponsor, a comprehensive freelancing website catering to the unique niche of social media influencer marketing. From conceptualization to execution, I meticulously designed and developed the platform from scratch, ensuring a seamless and user-friendly experience for sponsors and freelancers alike. By leveraging cutting-edge technologies and intuitive design principles, I created a dynamic marketplace where sponsors could effortlessly post their projects, and freelancers could apply to become social media influencers for promotional campaigns. The platform facilitated a seamless hiring process, allowing sponsors to review and select the most suitable influencers for promoting their products or services. By providing a user-friendly interface, sponsors gained access to a diverse pool of talented freelancers, and influencers had the opportunity to showcase their capabilities and secure exciting marketing opportunities. My role in building this freelancing website has contributed to the success of numerous promotional campaigns, connecting sponsors with the perfect social media influencers to reach wider audiences and achieve marketing objectives.
