I don't just wrap APIs. I build the algorithms underneath them.
I'm an AI engineer with 8+ years across quantum-simulation ML, fintech, EdTech, and clinical research โ and an MS in Theoretical Chemistry. I train transformers from scratch, invent production retrieval algorithms, and ship AI inside a $660M global Clinical Research Organization where "almost right" doesn't pass.
If your last contractor handed you a LangChain demo and called it a product, we should talk.
๐น What Sets Me Apart
โ Inventor of the Fox-Search Algorithm โ a hybrid vector + graph retrieval method I built for asymmetric query/target search (short questions against 200-page clinical protocols). Pairs a trainable ~0.3B-parameter BERT-tier model with FAISS where pure embedding search collapses.
โ I train my own models โ fine-tuning a 0.3B encoder is normal work for me, not outsourced to a Hugging Face checkpoint.
โ Scientific rigor โ career started predicting atomistic energies and forces for ab-initio-quality molecular simulations. Same measurable-accuracy discipline now applied to LLM systems.
โ Founder of edup.ai โ autonomous grading of handwritten STEM work: computer vision + handwriting recognition + math reasoning + rubric generation, end-to-end.
โ Production AI in a regulated industry โ currently building document intelligence at Worldwide Clinical Trials (2,900+ employees, 52 countries).
๐น Core Capabilities
โช RAG done right โ hybrid vector+graph retrieval, FAISS at scale, embedding fine-tuning, evaluation harnesses that actually measure quality. If your RAG hallucinates, I can usually tell you why within an hour.
โช LLM engineering โ self-optimizing prompt primitives that improve over time, constrained generation, tool calling, structured outputs. GPT-4o, Claude, Llama, Mistral.
โช Document intelligence โ production parsers for PDF, DOCX, XLSX with section-aware XML processing; semantic search that finds alternative phrasings of previously-approved language.
โช Custom model training โ BERT-tier encoders, LoRA/QLoRA fine-tuning, domain-adaptive pretraining.
โช Computer vision โ handwriting recognition, OCR, ViT/CLIP, math symbol understanding.
โช High-performance engineering โ C++ on the hot path, FastAPI services, real async Python.
๐น Tech Stack
โข Languages: Python, C++, JavaScript / TypeScript
โข ML / DL: PyTorch, TensorFlow, Hugging Face Transformers, scikit-learn, NumPy, Pandas
โข LLM: OpenAI GPT-4o / o-series, Claude, Llama, Mistral, LangChain, LangGraph, LlamaIndex, LoRA / QLoRA, RAG, function calling
โข Retrieval: FAISS, Pinecone, Weaviate, Chroma, Qdrant, custom hybrid vector+graph search
โข Vision: OpenCV, PyTorch Vision, ViT, CLIP, OCR, handwriting recognition
โข Backend: FastAPI, Flask, Docker, REST, WebSockets, async Python
โข Frontend: Svelte 4, React
โข Enterprise: Microsoft Entra ID, SharePoint, Azure, AWS, GCP
๐น Shipped Projects
โช Fox-Search RAG โ hybrid vector+graph retrieval running in production for clinical document Q&A, outperforming pure embedding baselines on long-form documents.
โช Self-optimizing prompt infrastructure โ reusable LLM primitives that improve over time without manual prompt-tuning.
โช Document intelligence backend โ parses Excel/DOCX/PDF with section-level XML comprehension; powers cross-document semantic search.
โช RFI automation for clinical trials โ ingests Excel-based Requests for Information and routes them through automated answer pipelines.
โช edup.ai โ 7-stage autonomous grading pipeline for handwritten math, from photo capture to gradebook. Live at edup.ai.
โช Neural network potentials โ ML approximations of quantum-mechanical energy surfaces for molecular simulation (same problem class as DeepMind's AlphaFold lineage).
๐น How I Work
โ I scope honestly โ if your problem doesn't need AI, I'll tell you.
โ I write the evaluation code before the model code. Anyone can demo; I deliver something you can measure.
โ I ship in weekly increments โ no six-week silence followed by a "big reveal."
โ I write maintainable code your team can own after I'm gone.
๐น Best Fit For
Teams stuck on "our RAG kinda works but hallucinates" โข Document-heavy domains (clinical, legal, scientific, financial, EdTech) โข Startups needing a senior engineer who can architect, train, deploy, and operate โข Anyone whose roadmap requires training models, not just prompting them.
Send me your problem โ not your solution. I'll reply within 24 hours with an honest read on whether I'm the right engineer for it.

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 โ 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 โ from whiteboard to AWS deployment.
Recent work:
Built a multi-agent legal AI system โ 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 โ 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 โ 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 โ useful if your project involves multilingual content, MENA markets, or non-English document corpora.
I work autonomously and communicate proactively โ 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 โ let's talk.
