About Tévy

👩🏻‍💻 Freelance Fullstack Developerwith 10 years of experience, specializing inRuby on Rails(back-end) andVue.js(front-end).

I help startups, SMEs, and web agencies **develop robust, scalable, and well-structured applications and APIs**, where quality, maintainability, and stability are key concerns.

I also bring **real strategic value**: autonomous and rigorous, I can **quickly understand very different business contexts**, **challenge requests**, and **propose sustainable technical solutions**, always aligned with client needs.

Imaster the entire modern stack(Rails 7, PostgreSQL, RSpec, Vue 3, Vite, Cypress...) and I stay updated daily on technological advancements to offer the best solutions.

I can adapt to therapid evolution of technologiesand fully leverage **artificial intelligence tools**: whether as development assistants (time savings, technical support, automation) or by directly integrating new AI libraries into client products (chatbots, business process automation...).
