Last project: a multi-agent system that handles end-to-end case evaluation for a legal client, replacing what used to be hours of manual review. That's the kind of problem I like — turning a messy, manual workflow into a reliable automated system.
I'm a Senior AI Engineer (5+ years) specializing in RAG pipelines, multi-agent architectures, and production LLM systems — from whiteboard to AWS deployment.
Recent work:
Built a multi-agent legal AI system — a conversational intake agent that evaluates cases and recommends outcomes in real time
Designed a RAG pipeline over a dense regulatory corpus, cutting document retrieval time by 60%+
Built an e-commerce shopping agent (Amazon/eBay) using LLM-based intent classification — replacing hardcoded category logic with a dynamic query mapper
Shipped scalable AI APIs handling thousands of daily requests at sub-200ms latency
What I bring beyond code:
I scope projects like a product engineer first — defining what "done" actually means (POC vs. production-ready) before writing a line of code. That means clearer expectations, fewer pivots, and timelines that hold.
Stack:
Languages: Python, Node.js
LLM frameworks: LangChain, LlamaIndex, OpenAI, Claude, HuggingFace, Ollama
Vector DBs: Pinecone, Weaviate, ChromaDB, pgvector
Agent frameworks: AutoGen, CrewAI, LangGraph
Cloud & MLOps: AWS (SageMaker, Bedrock, Lambda, S3, EC2), Docker, FastAPI
Databases: PostgreSQL, MongoDB, Redis
Search: Elasticsearch, FAISS
Bonus: I also work fluently across English, French, and Arabic — useful if your project involves multilingual content, MENA markets, or non-English document corpora.
I work autonomously and communicate proactively — you'll know exactly where a project stands at every stage, with no surprises near a deadline.
If you need an AI engineer who can own both technical architecture and product judgment — let's talk.

Senior Full stack AI Engineer specializing in LangGraph agents, enterprise RAG, and FastAPI
backends 3,300+ concurrent users in production across GCP and Azure.
I build the Python infrastructure that makes Large Language Model systems
production-ready. Stateful multi-agent orchestration, Retrieval-Augmented
Generation pipelines, LLM routing, and FastAPI backends deployed, monitored,
and running at scale. Not prototypes. Not demos. Systems with real users.
WHAT I'VE SHIPPED PRODUCTION, NOT DEMOS
↳ Multi-agent HR automation — LangGraph + GPT-4o → Azure → cut recruiter
processing time by 70%, serving 1,500 concurrent users in production
↳ RAG Assistant — Gemini + hybrid retrieval → GCP + Kubernetes → reduced
query resolution time by 60%, handling 1,800 concurrent users at peak
↳ Legal RAG system — 500+ document corpus, custom chunker, LangChain
evaluators → improved retrieval accuracy by 40% over baseline vector search
↳ Agentic travel system — LangGraph Cloud + GCP, full observability via
LangSmith → end-to-end AI App Development with zero manual intervention
↳ Agent Builder platform — Gumloop-style visual builder, LangSmith tracing,
live Generative AI workflows serving production traffic
↳ AI Email Automation — FastAPI + NLP classification + RAG pipeline →
eliminated 80% of manual triage work for the client's support team
Read this section first. Stack choices below are context. Systems above are the proof.
WHAT I BUILD

→ LangChain pipelines with conditional branching and parallel sub-agent execution
→ Human-in-the-loop approval flows for regulated or high-stakes workflows
→ LLM evaluation pipelines — automated scoring, regression testing, drift detection
→ LLM Fine-Tuning via LoRA / QLoRA on domain-specific datasets for
task-optimized models that outperform general-purpose OpenAI API calls
Enterprise RAG — Beyond Basic Retrieval
→ Hybrid retrieval combining Neo4j knowledge graphs and Vector Database
search (Pinecone, FAISS, Weaviate) — the architecture that works on
complex multi-hop queries where standard RAG fails
→ Multi-index pipelines with cross-encoder re-ranking for precision at scale
→ Custom runtime chunkers for domain-specific corpora (legal, HR, CRM, financial)
→ LangChain evaluators with measurable Retrieval-Augmented Generation accuracy
