At Salomon, I was brought in to architect and implement AWS-based serverless microservices that handle secure, high-volume data exchanges with external business vendors. I engineered resilient workflows using Lambda and EventBridge, implementing dead-letter queues to ensure fault tolerance. Working end-to-end, I also led the design of OpenAPI contracts, built CI/CD pipelines with GitLab, and enforced complete test coverage using Jest to guarantee deployment stability. This role has strengthened my ability to deliver robust systems in mission-critical production environments.

My time at Betclic was marked by fast-paced, high-impact work on real-time systems operating at scale. I migrated critical Angular components, designed a serverless promotional code API with AWS Lambda, and orchestrated EC2 scaling to handle over 20 million daily requests during high-traffic events. As part of both the Data and Analytics teams, I contributed to streaming pipelines, fraud detection tools, and real-time dashboards using tools like Kinesis and Snowflake. I also mentored new hires and improved onboarding documentation to streamline knowledge sharing across teams.

Creating the tourism app under MightySloth was my first venture into full product ownership—from backend design to frontend UX and cloud infrastructure. I developed the app using NestJS, Firebase, and Google Cloud, integrating real-time notifications, event-based geolocation, and a secure OAuth login system. Winning the Total Énergie innovation prize in 2021 validated not just the technical solution but the user-centered vision I brought to life. This project honed my ability to merge engineering with entrepreneurial thinking.

I led development on a privacy-first crowd counting tool using Rust and Rocket, designed for public demonstrations. The system relied on real-time Bluetooth interaction and geospatial analysis via Turf.js, ensuring anonymity while validating crowd authenticity. The app ran on Azure and featured a mobile UI built in Ionic, combining performance, usability, and ethical data handling in a politically sensitive context.

For this project, I created a real-time restaurant management app integrating Stripe payments, dynamic content updates, and native notifications. I used Loopback with PostgreSQL and MongoDB on the backend and Angular/Ionic for the UI. The live order system leveraged WebSockets, allowing restaurants to manage customer interactions with instant feedback. I optimized the platform for performance and stability through Jest-based testing and Lighthouse audits.
