About Josué

With 11 years of experience as a front-end developer in software publishers, ESNs, and for end clients, I have acquired solid expertise in designing and integrating performant, accessible, and user-centered web interfaces. My approach combines technical rigor with design sensibility, from POC to production, including optimization and responsive design.

My key skills

✅ Versatility:
Angular (in-depth professional experience): development of complex applications, maintenance, optimization.
React (personal projects and rapid upskilling): ability to quickly adapt to new stacks or advise on best practices.
Mastery of fundamentals: JavaScript (ES6+), HTML5, CSS3, and modern tools (Webpack, Babel, Git).

✅ Dual Dev/UX Skillset:
Close collaboration with designers, product owners, QA service, and project managers (tools: Figma, Adobe XD) and other developers (Git, Docker, Jira & Redmine) for pixel-perfect integration and optimal user experience.
Sensitivity to accessibility (WCAG) and ergonomics challenges.

✅ Autonomy and Flexibility:
Accustomed to remote work (3 to 5 days per week) and short-term assignments (2-3 months).
No team management: 100% focused on code quality and added value for your projects.

✅ Diverse Sectors:
Experience in diverse environments: software, e-commerce, fintech, with a particular appetite for projects where quality takes precedence over quantity and where collaboration between design and development is essential.
