TownSync (Dabu): Community Engagement SaaS
TownSync is a civic-tech solution designed to bridge the gap between residents and administrators. I implemented a robust backend using Sequelize ORM with MySQL to handle complex relationships between user reports and admin responses. The system features secure OTP authentication via Aakash SMS API, ensuring verified community interactions. The UI was built with React for a seamless, SPA (Single Page Application) experience.
Solution
Developed a middleware-based API architecture to handle SMS triggers and utilized Sequelize hooks for automated database updates during reporting cycles.
Outcome
Delivered a centralized community hub that streamlines civic engagement and provides administrators with real-time data on local issues.
