Hey, I'm Afzal 👋

I build AI-native products that ship — from LLM integrations and voice AI systems to scalable full-stack platforms. With 6+ years of experience across production AI systems and cloud architectures, I've worked with teams across the UK, Europe, and Pakistan to deliver software that actually moves the needle.

This blog is where I share what I pick up along the way — deep dives into AI engineering, full-stack patterns, and the tools I rely on day-to-day. If you're building with LLMs, voice AI, or modern web tech, you're in the right place.

What I write about

  • LLM integration, RAG pipelines, and prompt engineering
  • Voice AI with LiveKit, Deepgram, and real-time audio
  • Next.js, React, and full-stack TypeScript patterns
  • Python backends with FastAPI and async architectures
  • Cloud infrastructure on AWS & GCP
