Crafting secure, scalable, and intelligent backend systems with Django and Python

About Me

I'm a Backend Engineer with 2+ years of professional experience building 30+ production-grade Django systems across healthcare, fintech, logistics, and education sectors.

Proven track record of leading backend teams, reducing API latency by up to 30%, and integrating real-time and AI-driven features into scalable architectures — from WebSockets and Celery to VAPI AI and OpenAI integrations.

Currently working as Jr. Backend Developer at JVAI, building platforms like QuranApp, OrbitalFitness, EduTutor, and a multi-vendor eCommerce system (Hilliye) with 30+ endpoints.
