Long-Term Tech Partner Wanted — Must Have Shipped an App with 1M+ Downloads

We're building a mobile app (iOS & Android) inspired by Only2U — combining AI virtual try-on with a smooth shopping experience. We're serious about this, and we're looking for a serious partner. What we need: Proven scale experience — you must have personally built or led development on an app that hit 1 million+ downloads. Please share that project in your proposal. Algorithm know-how — comfort designing or implementing personalization/recommendation logic (not just CRUD app development). Long-term partnership, not a one-off job — we're not hiring for a single sprint. We want someone who can grow with us across multiple phases as the product scales. We already have an active customer database ready to onboard once the app is live — this isn't a "maybe someday" idea, it's a real business ready to move. Please apply with: your relevant 1M+ download project, your approach to recommendation/algorithm work, and your availability for a long-term engagement. app link - https://only2u.app/collection/4b9b207d-5606-4f1a-821e-1f502ca0d76c
