About Marc

Mobile developer for over 15 years, I support startups and companies in the design and development of mobile applications, from scratch creation to the evolution of existing applications.

Over my experiences (lead, CTO, production), I have maintained a pragmatic approach: understanding business challenges and transforming an idea into a concrete, reliable, maintainable, and performant product.

Today, I also specialize in the design and integration of artificial intelligence functionalities within mobile applications and digital products.

I work on complete application creations as well as on existing products to evolve, particularly through the addition of AI components.

Examples of interventions:

• creation of mobile applications (Flutter, Android)
• redesign or evolution of existing applications
• addition of an AI assistant (chat, business copilot)
• document analysis and structuring (OCR + LLM)
• image recognition and analysis (vision)
• content generation or process automation
• MVP design (mobile and/or AI)
• technical scoping, architecture, and technology choices
• performance and cost optimization (especially AI)

My approach:

• simple, robust, and scalable solutions
• product vision + technical excellence
• rapid and iterative deliveries
• team support if necessary

Main Stack:

• Mobile: Flutter, Android and native iOS
• AI: LLM, OCR, vision, automation
• Backend / API / architecture

I intervene:

• upstream: scoping, architecture, technical choices
• during: development, integration, support
• long-term: maintenance, evolutions, optimization

👉 Objective: transform an idea (mobile and/or AI) into a concrete, performant, and usable product.
