Freelancer profile translated to English.
Back to original languageAbout Damien
I spent the last 7 years in very early-stage startups likeComet(where I was employee #10) andFigures(employee #4). I was able to hone my pragmatism and focus in highly uncertain contexts and with limited resources.
I am primarily experienced in theNode.jsstack, particularlyTypescript + Reactand its entire ecosystem (Next,Prisma,GraphQL, etc...).
Through my experiences, I have also developed my skills inPython, whether for application development or basic data engineering.
More recently, I had the opportunity to dive into LLM stacks (LangChain,LlamaIndex,Literal AI). In an environment still dominated by the hard-science aspect, I was able to bring my softer, product- and user-experience-oriented perspective.
If you are looking for a freelancer who is not afraid to talk to users, challenge product decisions, and negotiate cross-team results -let's discuss!
By the way, I've been full-remote since 2012 🏝️✌️
