Aurélien Courreges-Clercq

Freelance data streaming & AI architect, for real-time systems that work in production. 15 years of field experience, École des Mines d’Alès, French engineer. Extensive experience in trading floors, banking, telecom, e-gaming, and tech startups. I do this job, at the intersection of data and AI, to automate tedious and repetitive tasks for teams.

I design, stabilize, and modernize real-time backends and data pipelines that must handle load, typically on Kafka, in Java, Scala, or Python, deployed in your cloud (AWS) or on-premise environments. I help you launch or improve event streams, analytics APIs, live dashboards, and AI automations without exploding latency, costs, or technical debt.

When relevant, I add an AI layer to your existing data, for example via RAG for internal document search or operational assistance, with a measured cost per query before scaling.

My core business is not optimizing heavy models, but the architecture of backends and data pipelines that hold under load. When your backend is too legacy, I help you prepare it through a few steps of rapid modernization, Strangler Pattern, and targeted microservice decomposition.

I leave you with systems that run, with runbooks, tests, and documented architecture decisions, so your teams can continue to evolve the platform without depending on me.

I work in short iterations, with a prototype close to production conditions from the start. We test latency and costs, then optimize before scaling on your Kubernetes clusters and cloud.

If you have a real-time data pipeline, a Kafka/cloud platform, a legacy migration, or an AI project to secure, I offer a short discussion to qualify your needs.
