At Ceynetics Systems (Pvt) Ltd, I delivered two Flutter mobile applications: a fitness tracker backed by 22,000+ exercises and an AI expense tracker integrated with the Gemini API. I also migrated Firebase collections to PostgreSQL and introduced Valkey caching.

On Project Echo, I implemented an authenticated WhatsApp bridge and developed the Flutter client. In EventNet Microservices, I developed JWT-protected payment and refund endpoints and integrated RabbitMQ event flows. My project work also includes database security, secure file transfer, and computer vision.
