About

Professional summary

I am an AI Engineer with years of hands-on experience building production-ready generative AI, machine learning, and data solutions.

I specialize in RAG systems, LLM agents, prompt engineering, and AI workflow automation. I have built a RAG agent on BigQuery using Vertex AI and integrated it into HubSpot so employees can access internal knowledge directly from their CRM.

I also develop practical AI automation for customer-facing operations. For an e-commerce fashion brand, I deployed an n8n AI agent that handles 50–100 Instagram customer messages daily and automated order-related workflows.

My machine learning experience includes computer vision and anomaly detection for railway safety. I have worked with U-Net segmentation, autoencoders, and YOLOv8 for real-time signal recognition.

I am comfortable across the full delivery lifecycle, from data modeling and data quality to backend development, cloud deployment, and MLOps. My technical stack includes Python, SQL, GCP, AWS, Docker, Kubernetes, BigQuery, PostgreSQL, and Supabase.

I am currently available and open to relocation, seeking opportunities where I can build impactful AI products and intelligent data systems.

Career history

Data & AI Engineer (Freelance) Ghazeline

I designed the PostgreSQL and Supabase data model for a women's fashion e-commerce store, covering products, variants, categories, stock, and orders for a catalog of more than 30 products.

I deployed an n8n AI agent that answers 50–100 daily Instagram customer messages, allowing the team to focus on complex requests. I also built backend data-collection features, automated order summaries and cash-on-delivery confirmations, and maintain the production store based on business feedback.

ML Engineer Infrabel (RideOnTrack project)

I developed an anomaly-detection system for Belgian railway tracks using machine learning and computer vision. The solution combined a U-Net segmentation model and an autoencoder to isolate critical areas and support targeted inspections.

I also integrated YOLOv8 for real-time train signal recognition, achieving 91% accuracy.

Generative AI Engineer Algorhythm

I built a RAG agent using Vertex AI over internal BigQuery data and integrated it into HubSpot for approximately 50 employees. This enabled employees to retrieve answers from company data without leaving their CRM.

I also developed Vertex AI workflows that automated recurring internal writing tasks while maintaining a consistent, specialized tone.

Data Engineering & Data Quality Intern Algorhythm

I built a data observability proof of concept focused on automated and manual data-quality validation.

I automated dbt tests and connected their results with manual data-quality checks in OpenMetadata, providing improved visibility into data quality.
