About

I’m Stéphane Blondel, a fullstack developer with 10+ years of experience building production-grade applications with TypeScript, React, Node.js and NestJS, with strong expertise in microservices and event-driven architectures. I enjoy turning product ideas into reliable features—designing APIs, shaping technical architecture decisions, and collaborating closely with teams through code reviews and engineering standards.

Over the years, I’ve delivered connected and offline experiences, healthcare and logistics platforms, and retail solutions used by international organizations. Most recently, I build and operate customer-facing and boutique operations apps (appointments, customer data and merchandising) on Azure, handling CI/CD, monitoring, and incident resolution to keep services running smoothly for real users.
