# Hugo Sequier — Data Scientist & AI Engineer

Canonical URL: https://hugosequier.com/

I turn complex operational inputs into production-ready AI systems, from agents and computer vision to document intelligence and workflow interfaces. My systems work with technical documents, video, floorplans, APIs, and the people who use them.

I am available for long-term collaborations in AI engineering, computer vision, data science, and workflow automation.

My focused offer is the Controlled AI Workflow Diagnostic for technical teams that need evidence, controls, and a go/no-go recommendation before investing in an AI pilot.

## [Controlled AI Workflow Diagnostic](https://hugosequier.com/services/ai-workflow-diagnostic/)

For €4,000 excluding VAT, assess one AI-assisted document or plan workflow across 10 business days before considering production integration. The diagnostic maps the operating boundary, baseline, representative cases, model failure modes, permissions, deterministic controls, human approval, logs, fallback, and recovery.

The fixed input boundary is up to three stakeholder interviews, up to three data or document categories, and approximately 5–10 sanitized examples supplied or validated by the client team. Five core artifacts are delivered: a bounded workflow map, evaluation summary, permission matrix, observable failure register, and go/no-go recommendation. A controlled pilot specification is added only when the evidence supports moving forward. Production deployment and professional compliance sign-off are outside the diagnostic.

Share one workflow through the [non-confidential detailed assessment](https://hugosequier.com/services/ai-workflow-diagnostic/#assessment).

## Selected work

### [AnalyzTech](https://hugosequier.com/projects/automate-v3/)

AI-powered verification workspace for floorplans and large construction documents. It replaces manual document reading and hand-run plan checks with document AI, computer vision, and compliance workflows. Reported impact: 80% time saved, 50% productivity improvement, 99% classification precision, and 96% room-mask precision.

### [Floorplan Computer Vision](https://hugosequier.com/projects/btp-computer-vision/)

Reusable data collection, training, evaluation, and inference workflows for floorplan polygon detection. Reported results: 88 mAP@50 for furniture and 60 mAP@75 for rooms.

### [Video to Report](https://hugosequier.com/projects/btp-v2r/)

Pipeline that analyzes construction-site videos and produces draft compliance reports. More than 300 hours of video analyzed; approximately three hours saved per project on report drafting.

### [Floorplan Automation Pipeline](https://hugosequier.com/projects/btp-automation/)

Production pipeline that transforms floorplan PDFs into verification workflows for technical controllers. Reported impact: 30% productivity gain, 90,000 hours saved, and approximately EUR 2 million in economic impact.

## Expertise

- AI agents, RAG, LLM applications, and workflow automation
- Computer vision, model training, segmentation, and evaluation
- Floorplans, construction documents, compliance, and standards automation
- Python, FastAPI, TypeScript, React, PostgreSQL, Docker, and AWS

## How I work

I frame the operational goal, map features and dependencies, validate priorities with the team, ship a functional MVP, iterate using real usage, and then stabilize and transfer the system to operations.

## Background

I hold an engineering degree specializing in Data and Artificial Intelligence. I have seven years of software-development experience and three years in data science. At BTP Consultants, I built end-to-end computer-vision pipelines, RAG architectures for large documents, APIs for floorplan interaction, and AI agents that helped reduce verification time by 80%.
