Magick Box

All AI models, one platform — a consumer AI app for iOS & Android, live on the App Store.

Consumer AI, shipped

Multi-model chat · AI personas in group chats · image, video & music generation · community feed

Team of 10 — my lead Role Development Team Lead · backend architect Stack React Native · FastAPI · MongoDB · Celery/Redis · Kubernetes

Led the ten-person team from first commit to a live App Store release — architecture decisions, code review, release management.
Architected and built the backend: async FastAPI + MongoDB, AI/ML API as the primary model gateway with Replicate as fallback, and Celery/Redis queues that keep long-running video and music generation smooth.
Built the monetization stack — Stripe billing with custom product setup on the web, RevenueCat in-app purchases on iOS and Android.
Deployed on Kubernetes with Helm; CI/CD via GitHub Actions.

App-store expertise

Guideline compliance, policy alignment, metadata and review notes, resubmission strategy: the unglamorous work that gets apps actually released, done repeatedly, plus fully scripted submissions via the App Store Connect API.
