Featured Projects
ShareTrip ā Accounting Platform with Real-Time Consolidation
I developed the accounting platform for ShareTrip, an audit-ready double-entry system built for high-volume transactions. It supports real-time consolidation across products, automated journal entries, and accurate ledger posting with 95ā100% success. The platform improved reporting performance by ~40% through optimized queries, indexing, and scalable data pipelines.
Business POS with Integrated Double-Entry Accounting System
I designed and developed a Point of Sale (POS) and finance system that automatically handles accounting in the background while users focus on sales and purchases. Whenever a sale, purchase, or return is made in the POS, the system generates the correct double-entry journal records automatically, keeping the accounts always up to date and audit-ready.
HuhuLive ā Streaming Backend for a TikTok-Like Real-Time Live Platform
I developed the backend and admin panel for HuhuLive, a real-time live streaming platform similar to TikTok Live. The app lets hosts go live with video or audio rooms, receive gifts from viewers, and earn coins that can be converted to real money. The backend handles live video streaming, real-time chat, gift transactions, and user management.
