Description

Software Architect & Senior Mobile Developer

Flutter • Android • iOS

Building an application is one thing. Designing a product that can evolve over several years while controlling costs is another.

For over 25 years, I have been designing applications and software architectures built to last. I support companies in creating mobile applications, modernizing existing products, technical audits, and architectural choices.

I primarily work on Flutter, Android, iOS, and Go projects, whether for developing a new application, taking over an existing one, redesigning, functional evolution, or team reinforcement.

As a publisher of my own applications, I design, develop, and operate products used by tens of thousands of users. This experience confronts me daily with the challenges of maintenance, scaling, performance, software quality, and operating costs.

Beyond development, I pay particular attention to the product's technical trajectory. Every architectural decision is designed to support the application's growth, anticipate future needs, and sustainably limit technical debt.

I get involved in all or part of a project:

🔸 Flutter, Android, and iOS Development

🔸 Go Backend and APIs

🔸 Software Architecture

🔸 Technical Audit and Architecture Review

🔸 Performance Optimization

🔸 Embedded AI (on-device) and AI Integration

Depending on the needs, I work on a fixed-price basis for a defined scope or on a time-and-materials basis to sustainably strengthen a team.

Going live is just one step. My goal is to design robust, scalable, and sustainable applications that can support your business growth long-term.

In 2019**, I co-founded **Kavacodewith the goal of designing sustainable, high-performance, and economically viable mobile applications. This entrepreneurial venture led me to develop my own products while supporting companies in their digital projects.

This dual experience as a publisher and service provider now enriches each of my assignments.

**Since 2026**, I have been practicing this activity as a **freelance developer**, on a fixed-price or time-and-materials basis, to directly support companies in their projects.

Building an application is one thing. Designing a product that can evolve over several years while controlling costs is another.

What I do

I am involved in creating new products, modernizing existing applications, technical audits, architecture reviews, and supporting development teams.

My areas of expertise coverFlutter**, **Android**, **iOS**, **Gobackends, API design, software architecture, performance optimization, and embedded AI integration.

My experience

As a publisher of my own applications, I design, develop, and operate products used daily. **Wano Collector**, for example, currently has **over 40,000 users**.

This experience allows me to approach each project with a long-term vision, considering the challenges of maintenance, performance, scaling, and operating costs.

Each technical decision is guided by the same objective: to build an architecture capable of supporting the product's growth, sustainably limiting technical debt, and controlling evolution costs.

October 2012 - August 2016 (3 years and 11 months)
Lyon, France
As a consultant from 2012 to 2016 at Sopra Steria, I supported several major clients such as EDF, SNCF, bioMérieux, and the Rhône-Alpes Regional Council on projects involving software development, information system architecture, and mobility.

These assignments allowed me to work on a wide variety of issues: C/C++ development, Android, iOS, and web technologies, software architecture, technical audits, industrialization, technical lead, and team support.

I worked in demanding environments where software quality, performance, security, and application longevity were major concerns.

This diversity of projects has significantly contributed to shaping my current approach to software architecture: designing solutions that can evolve sustainably while managing their complexity.
