At Ami Probashi Limited, I engineered an automated issue ticketing system with priority routing and WebSocket notifications, reducing average resolution time by 40%. I also developed a Django/Python data-correction application that improved cross-platform data accuracy by 35%.

I designed and implemented a fingerprint registration and verification backend following ANSI INCITS 378 specifications. I also developed a real-time business analytics dashboard using MySQL and RESTful APIs, improving operational workflow efficiency by 25%.

For Ginza Xiaoma E-commerce, I architected a multi-tenant CRM platform with TypeScript, NestJS, and MySQL, and integrated WhatsApp, SMS, and email messaging into campaign workflows. I’ve also worked with Redis caching, Kafka, Docker, and AWS across backend systems.
