About
Senior Full-Stack & AI Engineer
I'm Muhammad Ramzan, a software engineer based in Lahore with 4+ years of building production systems end to end. I work across Laravel and FastAPI backends, React, Next.js and Vue frontends, Python AI services, and Flutter mobile apps. More than 12 of the apps I've built are live on the App Store and Play Store.
Focus Areas
What I Focus On
psychology
AI in real products
LLM features with LangChain, LangGraph and RAG, plus speech-to-text and OCR pipelines that run inside live systems.

Real-time systems
Video classes, calling and chat with WebRTC (LiveKit) and WebSockets (Laravel Reverb, Pusher).
health_and_safety
Healthcare software
HIPAA-compliant telehealth, FHIR and EHR integrations, and scheduling built around real clinical workflows.
Approach
How I Work
I like owning a product from the first conversation to production. I start by understanding the business problem, design the data model and APIs before writing features, and ship in small increments. I'm comfortable reading third-party API documentation and integrating systems that weren't built to work together, from EHRs and banking APIs to WhatsApp and payment gateways.
