About Jozwiak

Need to modernize your Data architecture or automate your complex processes with Generative AI?

Future ESEO engineer and currently specializing in Data Legacy Modernization within Aubay's Lab'Innov, I support companies in their transition to cutting-edge technological solutions. My approach combines solid software expertise (Java/Spring Boot, Angular) and advanced mastery of Artificial Intelligence tools (LLM, RAG, Python).


My Areas of Intervention:

Generative AI & LLM: Design and prototyping of LLM-based solutions (Codestral, Claude Code) for code generation, automated analysis, or intelligent document search (RAG).

Data Modernization (Modern Stack): Migration and optimization of legacy systems to modern environments using dbt, SQL, and Power BI.

Fullstack & DevOps Development: Creation of robust applications with Spring Boot and Angular, and setting up containerized environments with Docker.

Observability: Process reliability and traceability via OpenTelemetry.

Why work with me?

Dual Expertise: Capable of managing both data infrastructure and the user interface, as well as software intelligence.

Concrete Innovation: I have carried out complex projects such as a 3D imaging prediction system and a RAG tool for the medical sector.

Rigor & Adaptability: With experience in the banking sector (LCL) and a consulting firm (Aubay), I quickly adapt to your business challenges.

Available for one-off assignments or long-term remote projects. Let's discuss your project to transform your technical challenges into opportunities.
