Marc Barbier

Freelance developer specializing in the **creation and development of mobile applications**. I support companies, startups, and project leaders at every stage of their digital product, from the initial idea to **deployment on the stores (App Store and Google Play)**, including technical design, development, and performance optimization.

My goal is to offer **robust, scalable, and user-oriented mobile applications**, while ensuring smooth production deployment compliant with distribution platform requirements. Through a structured, results-oriented approach, I transform business needs into concrete, reliable, and market-ready mobile solutions.

My expertise covers the entire mobile application lifecycle:

• Needs analysis and functional scoping,

• Selection of appropriate technologies,

• Development of architecture and features,

• Integration of APIs and third-party services,

• Management of performance, security, and stability,

• Preparation, publication, and monitoring on the stores.

Deployment on the App Store and Google Playis an integral part of my support. I am proficient in the validation rules, technical constraints, and best practices imposed by Apple and Google: certificate configuration, developer account management, build preparation, app store listing optimization (metadata, versions, updates), as well as post-publication monitoring. This expertise helps avoid validation rejections and reduces time-to-market.

As a freelance professional on Malt, I make it a point of honor to offer **clear, transparent, and efficient collaboration**. Each mission begins with a discussion phase to precisely understand your business challenges, technical constraints, and short- and long-term objectives.
