Digital Twin Career Odyssey
Built & hosted 100% on my personal Zo Computer (danmugh.zo.space (http://danmugh.zo.space))
A fully immersive 3D galaxy where each planet is a chapter from my 6+ years as a Senior Frontend Engineer. Fly through my career, click planets for interactive case studies, all running live on Zo’s always-on cloud computer.
This is the wildest personal site I could build in the time, next level frontend + real Zo integration.

I architected and built a multi-service REST API in Rust using Actix Web. Implemented JWT auth with refresh token rotation, scoped API key generation, Argon2 password hashing, RBAC, and Redis-backed per-key rate limiting. Structured as a Cargo workspace with isolated crates (auth, orders, wallet, data). Load tested with wrk — sub-5ms p95 at 10k concurrent connections. Wrote integration tests covering all endpoints, 90%+ coverage.

Designed the UI from scratch and built the full site in Next.js with TypeScript. Implemented bilingual routing (French/English), a dynamic article system with image-rich content, photo gallery with album views, and external integrations (GoFundMe, Google Forms). Optimized for SEO and mobile performance. Handle all deployments, updates, and ongoing maintenance. The team publishes content independently using the system I built.

Built the entire platform solo using Next.js and TypeScript. Implemented real-time GPS tracking, a matching algorithm connecting riders to nearest drivers, and mobile money payment integration (M-Pesa, Airtel Money). Designed the UI in Figma and developed a driver registration and verification flow with document upload. Built a waitlist system that captured 1,400+ signups. Set up CI/CD, SEO optimization, and handle all deployment and maintenance.
