Hi — I'm Hassan, an AI and full-stack engineer based in Islamabad. I'm Principal Engineer at Coblack, and I work mostly with Next.js, FastAPI, and LLM/RAG systems.
What I'll write about
Mostly things I wish I'd had when I was figuring them out:
- Building RAG pipelines with FastAPI, LlamaIndex, and Elasticsearch
- Real-world Next.js 14 patterns (App Router, RSC, MDX)
- Async ingestion with Celery + Redis
- Solidity smart contracts and the off-chain plumbing around them
- Notes from shipping AI features that actually get used
Code blocks work
export function greet(name: string) {
return `hello, ${name}`;
}
Lists work
- Frontmatter drives metadata + JSON-LD.
- Each post gets its own dynamic OG image.
- RSS lives at /feed.xml.
If any of this is useful to you, reach out — I'm available for freelance and contract work.
