Freelancer profile translated to English.

Description

Senior software engineer & technical architect with over 15 years of experience, I support my clients in the design, development, and optimization of robust, scalable, and high-performance web and mobile applications.

Specialist in the .NET ecosystem and microservices architectures, I also work on modern front-end stacks (Vue.js, Angular, React) and cross-platform mobile (Flutter, React Native).

Accustomed to complex environments and strong constraints, I know how to solve critical problems, modernize existing systems, and implement scalable solutions. Since 2022, I have been exploring and integrating the contributions of artificial intelligence to enrich the solutions offered to my clients.

I rely on best practices (Clean Code, TDD, DDD, CI/CD) to guarantee quality deliverables. Autonomous and rigorous, I enjoy working in a team, sharing my knowledge, and accelerating the skills development of more junior profiles.

**Problem**: frequent order blockages linked to disorder in the processing of Shopify flows, heterogeneous and not very resilient inter-service communication.

**Constraints**: complex redesign project already underway, strong pressure on the deadline, backend team of 4 people including the CTO.

**Solutions**:
Development of specific business services for the microservices architecture (ORDER, DELIVERY_ORDER, etc.)
Implementation of a unified abstraction for inter-service communication
Migration of synchronous GraphQL calls to an asynchronous model (NestJS + Kafka)
Integration of centralized monitoring on Google Cloud
Creation of Docker scripts to quickly start more than 30 microservices locally, with targeted configurations for feature tests

**Results**: standardized communication between services, better resilience to flow errors, increased observability, and significant time savings for local testing.
