Technical Feasibility
SkillSwap leverages mature technologies and existing APIs, making it highly feasible for a small team to build. The mobile-first PWA approach reduces complexity compared to native apps, while AI-powered matching and location-based services are well-supported by platforms like OpenAI and Google Maps. The primary challenges include implementing a robust trust & safety system and optimizing the AI matching algorithm for hyperlocal contexts. With a focus on leveraging low-code tools and managed services, a functional MVP can be delivered within 8-10 weeks.
