Colin Blokkeel

Powerus is a Y Combinator backed startup building Germany's leading career platform for skilled trade professionals, think electricians, plumbers, mechanics, carpenters, and more. With over 200,000 registered workers, the platform matches candidates with permanent jobs based on their skills, location, and preferences, letting them apply with a single click.

I work in the Worker Squad, the team responsible for the entire B2C experience. The web and mobile platform that workers use to discover jobs, build their profiles, and manage applications. My day to day involves shipping features across the full stack. Angular on the frontend and NestJS on the backend, backed by MongoDB. Partnering closely with product and design to drive engagement and performance.

Beyond product work, I'm part of the Platform Guild, where I contribute to infrastructure and developer experience. Managing deployments with Kubernetes and Helm, working with AWS services, and keeping our systems reliable as we scale. I also take an active role in our internal guilds, leading initiatives that improve code quality, maintainability, and team productivity.

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.
