Experience
MotoNode
My primary technical contribution involved engineering a complex double-entry bookkeeping system to track workshop expenses and customer payments with 100% transactional integrity. I also designed and implemented a persistent local caching layer using SQLite to enable workshop owners to manage service bookings in areas with poor connectivity. I managed the entire product lifecycle, from database schema design to the final deployment on Google Play Console.
A Freelance Marketplace Platform
My core technical accountability was the design of a state-machine-based milestone system; this logic governed the end-to-end project lifecycle, from contract initiation to the secure release of payment upon task completion. I architected the front end with React Native for high-performance cross-platform delivery and built a scalable Node.js back end. Additionally, I implemented secure JSON Web Token (JWT) authentication and role-based access controls to protect user data and financial transaction history.
