About

I'm Erwan Benmansour, an AI/ML engineer who builds production systems at scale. I've led recommendation and bidding work at Huawei, architected anomaly detection and MLOps pipelines at BMW, and built petabyte-scale data infrastructure at Amazon. I work end-to-end — from modelling and training infrastructure to deployment, monitoring and stakeholder communication — and I care about systems that stay maintainable after the demo.

Experience

Roles across advertising, logistics, automotive and research.

  1. ML EngineerHuawei — Ireland Research Center

    Remote (contract)

    Jan 2026 — present

    Cross-team ML engineering for ads recommendation and bidding systems: data and ML pipelines, recommender model refactoring, service deployment and A/B testing.

  2. Research AssistantKuehne Logistics University

    Hamburg, Germany

    Oct 2025 — Dec 2025

    Researched reinforcement learning algorithms (DQN, A2C, PPO) for sequential decision problems in multi-echelon, multi-sourcing supply chain optimisation, and built the engineering around them: automated experiments, CI tests and distributed tuning.

How I work

My background is in computer science engineering and machine learning (UTC — Sorbonne Alliance), applied across advertising, logistics, automotive manufacturing and research. Since graduating I've focused on production ML: taking models from notebook to monitored, cost-controlled services.

At Amazon I built ETLs and evaluation APIs for European delivery operations. At BMW I architected a weakly-supervised anomaly detection system for supply chain irregularities and the full MLOps path around it — training, registry, monitoring, APIs and CI/CD. At Kuehne Logistics University I researched reinforcement learning for multi-echelon supply chain decisions. Today I do cross-team ML engineering for ads recommendation and bidding at Huawei's Ireland Research Center.

Alongside client work, my own projects push into causal auditing, federated learning, human-in-the-loop assistants and LLM serving performance. Whether you need a technical partner for an AI product, an ML lead for a critical system, or an outside opinion on an architecture you're about to commit to, the work looks the same: understand the constraint, measure the baseline, ship something maintainable.

Looking for a partner?

I take on a limited number of projects each quarter. If you have a challenging AI problem, I'd love to hear about it.
