Hi r/forhire,

I'm a Master's CS student at Arizona State University (3.87 GPA) with hands-on production experience building AI systems, not tutorials, not toy projects. Real systems, real users.

What I've actually shipped:

\- Enterprise document Q&A assistant used by 170+ employees across 1,800+ documents at \~3s response latency (LangChain, Pinecone, GPT-4o, FastAPI)

\- RAG Hallucination Detection system with semantic entropy scoring, Jensen-Shannon divergence, and DeBERTa NLI, which benchmarked on 198 research papers

\- Real-time AI pipeline synchronizing biosignals, facial capture, and video at frame-accurate precision

\- Speech recognition system: 96.27% accuracy on 35 commands, 11.4ms inference latency

\- ML prediction pipeline for a university research lab at 92% accuracy (TensorFlow, Scikit-learn)

What I can build for you:

✅ RAG pipelines (LangChain, LlamaIndex, Pinecone, ChromaDB)

✅ Document Q&A / internal knowledge assistants

✅ FastAPI AI backends and REST services

✅ LLM integration (OpenAI, Claude, HuggingFace)

✅ Vector database setup and semantic search

✅ Hallucination detection and output reliability layers

✅ ML model development and deployment (TensorFlow, PyTorch)

✅ Real-time data pipelines and WebSocket systems

✅ Code review, debugging, architecture consulting

Rates:

\- Consulting / architecture calls: $50/hr

\- Project work: quoted per scope (most small projects $150–$500)

\- Quick fixes / debugging: $40/hr

\- Payment: PayPal or Venmo, upfront for hourly, 50% deposit for projects

Turnaround: I'm available immediately and can deliver fast, 48-hour prototypes are genuinely on the table.

DM me with what you're building. I'll tell you honestly if I can help and how fast.
