Gautier Vanneste

I help finance and operations teams automate complex workflows with AI and custom software.

I combine workflow automation with custom software, APIs, LLM/agentic AI, testing, observability and financial-domain understanding to deliver reliable production systems.

Before software engineering, I spent four years as a Senior Auditor at KPMG, after earlier experience at Société Générale CIB across derivatives, risk advisory, M&A and private equity. This background helps me understand financial and operational workflows quickly, identify what must remain traceable, and test the parts that cannot quietly be wrong.

Selected work:

• Designed and built an accounting engine that generated 500+ French tax filings after four months of development, delivered by the regulatory deadline, then reached approximately 2,000 filings the following year

• Built fraud-detection tooling and real-time market monitoring for a crypto trading platform

• Currently building RideLvL’s agentic video-analysis pipeline, including evaluation, observability and testing infrastructure

I can help with:

• AI workflow automation using n8n, APIs and custom TypeScript or Python

• AI agents and LLM integrations

• Evaluation, observability and cost control for AI workflows

• Financial and operational software requiring correctness, traceability and reliable production delivery
