👋 Howdy, I'm Damien.
Portfolio gathering all you need to know about me, my work experiences, and tech principles learned over time.
Introduction
Graduated from a Master of Science in Information Systems from ESEO (2015). My career has taken me across France 🇫🇷, Germany 🇩🇪, and the United States 🇺🇸, enriching me with diverse cultural insights and expertise in various business domains and advanced technical stacks.
Foundations in Mobile development 🥚
I began my journey specializing in frontend development, focusing on creating intuitive mobile applications. This phase honed my skills in designing user-centric interfaces and optimizing API constructions to build seamless mobile solutions.
Expanding into Backend and Infrastructure 🐣
Eager to grasp the full stack, I sharpened my ability to build scalable and resilient systems—tightening app security, baking in reliable error handling, and thorough testing. Concurrently, I delved into infrastructure, implementing CI/CD pipelines for seamless deployments and leveraging infrastructure as code to maintain drift-free, reliable environments, including observability.
Leading Teams and Enhancing Delivery Processes 🐥
Transitioning into leadership roles, I focused on fostering team growth and facilitating constructive dialogues within a fun and inviting environment while maintaining rigorous standards. This balance, coupled with a mindful approach to reusability and broader organizational needs, stimulated engagement and innovation, streamlining processes and accelerating project delivery at both the project and company level.
Business-Minded Engineering 🐓
Today, I view productivity as accelerating cycle times and time to market, favoring pragmatic, high-impact solutions over perfection. Pragmatism doesn’t mean forfeiting quality; rather, it means making well-reasoned trade-offs while upholding robust engineering standards. I combine strong engineering with a business-driven mindset, optimizing delivery for value while managing technical debt to keep risks low. By doing so, I drive projects that not only address technical challenges but push the organization forward with real, timely, measurable wins.

Recommendations
« I supported Damien as his manager for almost 2 years. In that time Damien showed a tremendous work ethic and dedication to quality. He loved to discuss how to write and improve code, but unlike many who can talk in depth about the craft, he also followed through with quality, timely implementation. He served as a mentor for the more junior engineers on the team, and was open to coaching from more experienced team members. He also was a keen observer, with valuable insights which helped improve the team’s skills and dynamics. I would happily have Damien on my team again! »
« Damien is one of those software engineers that just made my life super easy. He is very well versed in not just software but infrastructure, and it is a trait that is hard to find these days. I could hand Damien any major task, and it would just be done well the first time. When it came to mentoring and coaching other engineers, Damien set the bar. His passion ensured they were well supported using a variety of techniques. This helped promote several engineers to the next level. I would have no hesitation recommending Damien for any future software project or team, and I always wish I could have Damien on my teams. »
