Building the
next web.
I'm John Tewolde — a creative developer who ships immersive websites, physics-based 3D games, and intelligent AI-powered applications.
Projects
ChaseUp
SaaS platform automating payment tracking, retainage management, and mechanics lien preparation for construction subcontractors.
Neon Racer 3D
Browser-native 3D racing game built from scratch — custom physics engine, dynamic camera system, and full synthwave neon aesthetic.

Expertise
Design Engineering
Bridging stunning visual craft with robust architecture. I build interfaces that are not just beautiful — they're fast, accessible, and alive.
Performant Web Apps
React, Next.js, and vanilla JS applications that load instantly, scale cleanly, and run on the edge — optimized from the first commit.
Applied AI & Physics
Integrating computer vision, ML models, and rigid-body physics simulations to craft experiences that feel genuinely next-generation.
Let's build something
remarkable.
I'm actively seeking ambitious projects, freelance contracts, and full-time roles. Whether it's a startup idea or an enterprise overhaul — let's talk.
