I’m a passionate Backend Engineer who thrives on architecting reliable, scalable, and AI-integrated systems. With deep hands-on experience in designing complex backend solutions, I build APIs that don't just serve — they scale, secure, and evolve.
🔧 I specialize in backend architecture, API development, and AI-integrated systems using modern JavaScript/TypeScript stacks.
💼 Over the years, I've engineered robust backend systems across diverse domains:
- 🛒 E-Commerce Platform – handled full backend including products, orders, cart, payments, user management, and admin dashboards
- 🏥 Hospital Management System – appointment flow, patient-doctor modules, secure health records, and billing
- 🎟️ Ticket Booking App – built scalable ticketing logic with real-time availability and notifications
- 🔁 Onsfer Platform – implemented push notifications, user messaging, real-time updates, and background workers
- 🎉 Event Management System – multi-role access, ticketing, QR scanning, and event analytics
- 🧾 iDocx: AI-powered OCR System – used DeepSeek-VL2, Gemini Pro, GPT-4 Vision, and Textract for intelligent document parsing
🧠 I’m obsessed with integrating LLMs and OCR engines with backend systems — turning raw documents and images into structured, searchable insights.
