ShariahEase
An Islamic-finance assistant that answers on WhatsApp, voice in and voice out. Explainable RAG under the hood: vetted sources, cited answers, fast inference. Accuracy first, always.
Available for new projects
I build AI systems that actually ship.
I'm Hasnain Zainulabdin. I build RAG pipelines, LLM apps, and FastAPI backends that make it out of the notebook and into production. Don't take my word for it, every project below is live. Click one and poke around.

Who I am
I turn scattered documents into assistants that answer with sources.
I put LLMs on WhatsApp, on the web, and behind APIs that don't fall over.
And I ship. Demos you can click, not decks you have to believe.
01 · Live work
Don't read about it. Try it.
Everything here is deployed and public. Open one, ask it something hard, judge me on the answer.
Legal AI
QanoonDaan
Ask about Pakistani law in plain language. A legal assistant grounded in statutes and precedent, built for quick, reliable references through a conversational interface.
Recruiting AI
ResuFit
Ranks a stack of resumes against any job description with semantic matching. Skill relevance, not keyword bingo. Built for recruiters who screen at volume.
02 · What I do
Three things, done properly.
No forty-item agency menu. This is what I actually build, because I've built it before.
01
RAG & knowledge assistants
Turn your documents into an assistant that answers with sources. Semantic retrieval, grounded responses, and an honest "I don't know" instead of confident nonsense.

LLM apps & chatbots
Conversational products on WhatsApp, web, and voice. Everything from prompt design and guardrails to speech-to-text and text-to-speech pipelines.

Backend APIs & deployment
FastAPI services with auth, validation, and Docker deploys. The unglamorous plumbing of shipping AI, done right so your product stays up.

03 · About
Backend-first, proof-driven.
I'm a Software Engineering graduate from the University of Sindh, specialized in AI and data science. I got into this field to solve real problems with language models, retrieval systems, and automation. Not to make demos that die in a notebook.
That's why everything I build is production-shaped from day one: proper APIs, proper error handling, deployed where you can actually use it.
- Advanced RAG and vector search optimization with FAISS and semantic retrieval.
- High-performance APIs with FastAPI, Pydantic, and Python.
- Hands-on with Llama 3, Groq inference, Hugging Face, spaCy, and scikit-learn.
- Multi-model conversational AI for practical, real-world workflows.
How I work
1
Scope
A short call, a clear written plan, and an honest estimate. No vague "AI magic" promises.
2
Build
Weekly demos you can click, not status reports. You see the thing working, not slides about it.
3
Ship
Deployed, documented, and handed over. You own the code and know how to run it.
