About me
Research-minded engineering, grounded in real products.
Software Engineer with experience turning research questions into practical systems. My work spans energy-aware machine learning for semantic web infrastructure, explainable AI applications, knowledge graphs, and modern full-stack products.
I enjoy moving between disciplines: understanding a problem, exploring the data, designing a maintainable architecture, and shaping an interface that makes the result approachable. Outside engineering, I am a self-taught artist, coffee enthusiast, and active learner.
Professional experience
From research questions to operational systems.
Experience across applied research, machine learning, semantic infrastructure, and enterprise IT.

Research internship
Research Software Engineer Intern
LIAS Laboratory
Jan 2025 - Jul 2025
Poitiers, France
Investigated the energy efficiency of RDF triple stores and built predictive machine-learning models to estimate the energy consumption of SPARQL queries.
- Designed empirical experiments around query processing and energy usage.
- Worked across semantic web infrastructure, data analysis, and predictive modelling.
- Documented reproducible workflows for research evaluation and comparison.
