I am an AI Full Stack Engineer with 4+ years of hands-on experience building production-grade SaaS platforms and AI systems used by real users not just demos.
I work end-to-end: architecture → development → AI integration → deployment, with a strong focus on scalability, clean code, and long-term maintainability. I’ve delivered modern SaaS products, AI-powered tools, admin dashboards, and cross-platform apps for startups and growing businesses.
My core strength is building real AI systems, not just API integrations. I design and deploy LLM pipelines (RAG, vector search, evaluation, tracing) and AI agents that operate reliably in production.

Hi, my name is Androux, but I usually go by Roux. I am an AI-enhanced developer, and I have been building software for 12 years.
These days, my workflow is heavily focused on AI. I use tools like Lovable, Codex, and Claude to build smarter and faster.
I also run PixelSpace, an agency where we bring next-generation AI products to life.
I absolutely love product development. For me, it is not just about writing code. It is about making sure the things I build actually work and feel great for the people who use them.
When I am not building for clients, I am usually building my own apps or teaching. I run a YouTube channel and a free Skool community dedicated to vvibe coding, where I help people learn how to leverage Lovable and other tools for their own projects.
How I can help you:
- Solo or Lead Developer: I can jump in at any stage to help turn your idea into a reality.
- Team Player: I am happy to integrate with your existing crew to help push your project forward.
- Agency Support: If your project grows and you need more hands, I have a trusted roster of developers at PixelSpace ready to step in.
I am always on the lookout for new and interesting projects. If you have an idea you want to build, please get in touch. Let's see if we can work together!
