Freelancer profile translated to English.

Description

Freelance since 2014 — 12 years of experience, including high-traffic consumer applications (Carrefour 5M+, Michelin 10M+).

Leading teams and projects: I frame the architecture, anticipate edge cases, and ensure consistency between the product vision, design, and tech.

I work across the entire stack — Mobile (Kotlin · Swift· Clean Archi), Java Spring Boot backend (REST API BFF), observability (Kibana · Gatling), CI/CD (GitLab) — with an AI-driven approach via Gemini / Claude CLI and MCP

Currently passionate about AI: training LLM models from scratch (karpathy/autoresearch), fine-tuning (Mistral 7B), and data parsing for building business datasets.
