Creation and development of Chromie, an iOS and Android mobile game designed, developed, and released from start to finish.

I act as the founder and lead developer, responsible for the product vision, technical architecture, fullstack development, and mobile publishing.

I designed the complete project architecture around an Nx monorepo, encompassing a React Native mobile application, web and back-office interfaces, NestJS backend services, a shared SDK, and several common technical components.

Development covers all product features: authentication, session management, user progression, game history, leaderboards, game mechanics, API integrations, cross-functional services, and mobile monetization via AdMob.

The mission also includes managing aspects specific to the mobile product lifecycle: performance, debugging, reliability, incident tracking, ad consent management, build configuration, iOS/Android signing, and publishing on the App Store and Google Play Store.

This experience demonstrates the ability to design, develop, structure, and operate a complete digital product, from the initial idea to its user availability.

From-scratch design of the architecture and development of a multi-tenant SaaS platform dedicated to growing social media profiles.

I had complete responsibility for the structuring technical choices, the design of the application foundation, and the implementation of the platform's initial architecture.

The solution was based on a microservices backend in Node.js/NestJS, several front-end interfaces in Next.js and Nuxt.js, an Angular back-office, PostgreSQL and MongoDB for data persistence, and RabbitMQ for asynchronous processing.

My involvement also covered the integration of several payment processors, the design of CI/CD pipelines, the management of development and production environments, and the consideration of cybersecurity issues from the architectural phase.

The objective was to build a robust, maintainable, and scalable technical foundation capable of supporting product evolution, multi-tenant isolation, critical external integrations, and platform scaling.

Acting as Angular Tech Lead within a team of 6 fullstack developers, on a complex Angular SaaS application involving a large volume of business rules undergoing significant technical refactoring.

The main challenge was to strengthen the front-end foundation and reduce the complexity associated with integrating with hypermedia/HATEOAS APIs. I designed abstractions, internal tools, and conventions enabling developers to consume these APIs more simply, reliably, and homogeneously, without having to directly manage the full complexity of hypermedia exchanges.

This intervention helped to better structure Angular development, secure API integration patterns, and provide a common technical framework to accelerate the development of business features.
