At MMS IT, I engineered full-stack features for commercial restaurant POS software, working in an Agile workflow with Laravel 12 and a Next.js client.
I built atomic checkout transactions to handle order items, dynamic taxes, cash change, and voucher generation. I also developed a real-time checkout cart with live quantity and price calculations.
For the Agent Banking & Remittance POS API project, I built a serverless REST API and an ACID-compliant double-entry ledger with atomic debit and credit mutations.
I also developed a cross-platform media discovery app with React Native and Expo, integrating Appwrite for authentication and cloud data. I optimized rendering with virtualized lists, cached images, and debounced search.
