Multi-Agent R&D Pipeline (3 Custom Agents)
Independent Project
Claude Code subagents, MCP, Pydantic V2, pytest, bandit
Designed and shipped 3 specialized agents that hand work down a line: a research agent writes a cited implementation spec, a coding agent builds the modular code and its tests, a review agent ranks findings by severity and applies the fixes. Each handoff is a structured document, so no stage depends on another agent's context window.
Connected the research agent to an academic-research MCP server (Semantic Scholar, ArXiv, Hugging Face Hub, citation snowballing) so every reference traces to a tool result rather than the model. Gated commits behind ruff, mypy, pytest and bandit, required human sign-off before installs and commits, and persisted session state on disk so long runs survive a context reset.
Agentic ERP Supply-Chain Copilot
Independent Project
LangGraph, MCP, OR-Tools, CVXPY, CRAG, DSPy, AKS
Split the work between the language model and code: a LangGraph orchestrator sorts each question into 1 of 10 types, the model handles the language, and 7 OR/CVXPY/SciPy solvers run the math behind typed Pydantic contracts. Code with provable guarantees executes the plan the model writes.
Built the safety net: a live 100-question test on the real classifier (90% accuracy gate), a retrieval pipeline (BGE-large, pyvector and BM25) that rewrites its own query when the documents returned are off-target (Recall@5 above 0.80), and a human sign-off on decisions above $10,000.
LLM Alignment Pipeline
Independent Project
PyTorch, Hugging Face, LoRA, QLoRA, DPO, MLflow
Fine-tuned Llama 3 8B on 6,000 FinQA examples via LoRA, raising token accuracy from 49.9% to 74.8%. Labeled 1,800 preference pairs with Zephyr 7B-β (RLAIF), then applied DPO to push reward accuracy to 98.1%. Graded with Prometheus 2, kept separate from Zephyr so no model marked its own work, tracked every run in MLflow, and published the adapter to Hugging Face (G-Maxime-N/llama3-8b-finqa-dpo).
Production RAG Chatbot
Independent Project
FastAPI, Chainlit, FAISS, LangChain, Docker, GitHub Actions
Built an async FastAPI service that streams answers token by token, remembers the last 12 turns of a conversation, and reports its own health. Fixed a thread-safety fault in an asyncio generator and removed a 230 MB cold-start delay behind Docker health checks.
Automated releases through GitHub Actions to GHCR so every deployed image traces back to the commit that produced it, and reached 0.8373 citation precision (ALCE) on questions spanning multiple scientific documents.
AI Research Consultant: LLM Reasoning and Agentic AI Evaluation
Outlier AI and Mercor
- Identify where a language model's step-by-step reasoning goes wrong on hard STEM problems and write the correction, which becomes the training signal (RLHF) that makes the next version of the model more accurate.
- Evaluate AI agents on whether they pick the right tool and stay on track across long tasks (ReAct-style reasoning, function calling, long-context management), and settle the ambiguous cases against a written rubric.
- Design the scoring rubrics and lead peer review to keep prompt engineering consistent across a distributed group, turning hard mathematical content into training data the team can trust.
Doctoral Research and Teaching Assistant
Ludwig Maximilian University of Munich
- Established the conditions under which stochastic gradient descent (SGD), the method behind almost all model training, is guaranteed to converge, showing engineers how aggressively they can train before a run falls apart.
- Delivered an explainable-AI (XAI) project that flags failures early in industrial power plants and gives the reason behind each alert. Reached F1 0.99 with 6 ensemble learners and SHAP, and held fairness across sites (Disparate Impact Ratio 0.95).
- Taught postgraduate optimization, machine learning and data science, and defended a disputed proof step before the Springer Nature editorial board through to acceptance.
Doctoral Research and Teaching Assistant
RWTH Aachen University
- Derived practical learning-rate conditions for gradient descent on deep networks that do not shrink exponentially as the network gets deeper, removing a limit that kept the earlier theory out of practical use.
- Backed the theory with large-scale PyTorch training runs on high-performance computing infrastructure, spreading the workload across nodes to cut the runtime of each experiment.
- Taught continuous optimization and mathematics of data science, and built course materials that made advanced theory concrete for engineering students, within a research group of 9 nationalities.
Machine Learning Intern
Group One Holding Company
- Analyzed telecom fuel-consumption data to pinpoint the root cause of fuel loss and compared 4 machine learning models (Gradient Boosting led at 98% Nash efficiency). Deployed the winning model as a Flask web application with a monitoring dashboard, securing 84,617 liters of fuel.
- Automated log ingestion, cutting reporting time from days to seconds, then presented the findings and the case for rollout to company managers and the operations director.

Summary
AI research scientist and machine learning engineer. Builds AI systems that reach real users, then proves they work with measured numbers. The current project is an AI assistant that takes a business question, splits it into steps, and picks the right tool for each step. It checks its own answer before a person sees it. An earlier project turned a fuel study into software that field technicians ran themselves, securing 84,617 liters of fuel and cutting reporting time from days to seconds. Springer Nature published the research side: how to train deep learning models faster and more reliably. Owns the problem from the first data pull through to the running service. Nothing goes live until it clears a test suite built for it.
