👋 About

I’m Kevin Josué Marville, also known as Kvnbbg in the open-source world, and Techandstream for commercial and freelance work. I design, build, and ship end-to-end digital products: reliable architectures, elegant UI/UX, and smooth cloud delivery — always with a DRY, SMART, ready-to-ship mindset.

Why teams work with me

• Product clarity: from idea to actionable roadmap and execution.
• Engineering depth: frontend, backend, mobile, DevOps, and cloud.
• Design sensibility: UX-first workflows, clean UI, and fast feedback loops.
• Delivery focus: scalable systems with production-grade polish.

🚀 What I build

• Web & Mobile Apps (React, Vue, Flutter, Kotlin, Node.js)
• Product Platforms (Dashboards, SaaS, marketplaces, content systems)
• 3D/Interactive Experiences (Three.js, motion design, immersive UI)
• Cloud Delivery (Docker, Kubernetes, AWS, CI/CD)

✨ Usability & Rendering Improvements

To avoid blank sections or broken visuals on GitHub/mobile, the README now:

• Uses lightweight, responsive cards with fallbacks.
• Groups core info at the top for instant visibility.
• Includes a self-hosted animated contact card (below) so key info always renders.
