# Junaid Afzal (Muhammad Junaid Afzal)

> Junaid Afzal is a Lahore, Pakistan-based software engineer building cross-platform mobile apps (Flutter, React Native) and scalable backends (NestJS microservices), with experience in AI integrations (GPT-4o, Whisper, RAG), real-time systems (LiveKit, WebSockets) and Solana dApps.

## Summary
I’m a software engineer with 1.5+ years of professional experience building cross-platform mobile apps and backend systems. I work across the stack — Flutter and React Native on the client; NestJS microservices, REST APIs and CI/CD on the server.

I lead mobile and backend workstreams of 5–8 member teams, coordinate with web developers and mentor junior engineers. Alongside work I’m completing my BS in Software Engineering at the University of Central Punjab (CGPA 3.92), teaching Programming Fundamentals as a teaching assistant, and going deeper into DevOps and distributed systems.
