As a Software Engineer at PowerUs — a fast‑growing Y Combinator–backed startup building the leading career platform for skilled trade professionals — I help develop and scale our full‑stack application. Partnering closely with product and design, I deliver user‑focused features that drive engagement and performance.

Beyond building for end users, I also focus on the developer experience by contributing to our internal guilds across frontend, backend, and our shared design system. There, I lead initiatives that improve code quality, maintainability, and team productivity.

In our lean, fast‑moving environment, I play an active role in shaping technical decisions, evolving best practices, and fostering a collaborative engineering culture as we scale our platform and impact.

Working as a full‑stack developer, building a Figma-like editor to allow users, primarily factories, to create screens to monitor their production.
The tech stack we're using :

• Frontend using Vue
• Express main API
• Multiple APIs in golang to handle auth / administration
• Workers in golang to fetch and process data from multiple sources
• Docker and helm for deployment

Transitioned from working independently to a two-person team, mentoring and collaborating with a junior developer.

Working as a full‑stack developer for Auchan, one of the largest France e-commerce website, my team was responsible for building, deploying, and maintaining features for the e-commerce website auchan.fr. The website was built using a hexagonal architecture. My team managed the following microservices :

• Customer Contextualization: Guiding customer journey choices from drive to home delivery.
• Store Data: Managing and updating information related to different stores.
• Tracking: Ensuring the proper functioning and continuous evolution of the website.
• Customer Feedback (CRM): Managing customer feedback to improve satisfaction.
• Digital Catalogs and Administration: Managing product catalogs via a carousel and creating an administration tool to facilitate catalog creation.
• Geolocation: Optimizing the customer journey based on the user's location.
• Content Management: Implementing and maintaining a Headless CMS for efficient content management.
• Product Pages / Slots: Ensuring an ideal presentation of products for an optimal user experience.

We were from two to five people in the team, using agile and scrum methods to keep organized.
