I'm Renaud Denis, an Agentic Engineer based in Belgium.

I build software from vision to production.

For more than 20 years, I have worked as a developer, architect, team leader, and CTO.

Today, my work has two essential dimensions. I take freelance missions for companies, and I build my own long-term products as solo founder.

In freelance missions, I work at two scopes depending on what is needed: C-level scope to define vision, roadmap, architecture, and delivery direction; architect scope to turn an existing direction into robust execution.

At EMAsphere, I recently delivered a full AI platform cycle from zero to production readiness, including Agent Service, MCP server, OIDC/OAuth2 + JWT security, a Front Reference Implementation, and an engineering instruction framework.

As Solo Founder & Principal Engineer at Tylium, I build a Rust and web ecosystem for audio software. Cutoff is both my product journey and my daily engineering lab.

Outside work, music has always been part of my life. I play keyboards (piano, Hammond organ, and synths), and nature is where I reset.

I dream big on vision and architecture, and I stay realistic on roadmap and delivery. Dream hard, deliver hard.
