Founder partnership
When you work with me, you work directly with the engineer building your product. No junior developers in the middle—just clear technical leadership and shipped software.
Technical Founder & Execution Partner
Rayen Kamta builds systems that ship.
Hands-on software engineer and CTO-for-hire for startup founders. I architect platforms, marketplaces, and AI workflow systems—then write the code and deploy to production. No layers, no handoffs.
About Rayen
I work directly with founders as a technical execution partner—combining CTO-level architecture with hands-on engineering. The focus is depth, discipline, and production readiness from day one.
Execution discipline
Clean architecture, secure authentication, role-based access, and deployments that hold up under real users and real revenue.
Scale from day one
Platforms and marketplaces designed to perform from launch—using proven cloud patterns on AWS serverless, MySQL, and Cloudflare edge infrastructure.
What I build
End-to-end technical ownership for founders who need a CTO who still writes code and owns production outcomes.
Platforms & marketplaces
Multi-sided products, transaction flows, admin tooling, and APIs engineered for growth and operational clarity.
AI workflow systems
Practical AI automation embedded in real business processes—not demos—integrated with your data and permissions model.
Cloud & edge infrastructure
Serverless backends, relational data modeling, and Cloudflare Workers for fast, secure global delivery.
