Three apps, one engineer

Three products, one engineer

All three ship on iOS and Android from one React Native codebase, published under Greenbull's technology entities — TechX on the App Store, Greenbull Technology DMCC on Google Play.

ARYA App is an investing assistant: a voice and text AI that answers questions about markets, price alerts that arrive with the reason attached, scheduled research reports, a community forum and a course library, sold as a subscription through in-app purchase in English and French.

ARYA Wealth Management holds a whole balance sheet: cash and equities, real estate with the mortgages attached to it, private equity, and asset classes the owner invents. It projects net worth years ahead, stress-tests those projections, prices in two currencies at once, and answers questions about the portfolio in plain language — on iPhone, on Mac, and on Vision Pro.

Greenbull Club is the private side: a members' feed, a searchable directory, bookings for masterclasses and property viewings, a QR membership card that opens the door at events, and partner benefits. It went from first release to a member directory with city and country filters in about six weeks.

What shipping alone actually requires

One engineer on three products cannot afford three architectures. The apps share component systems, state management, navigation and release pipelines across iOS, Android and web, so a fix lands once. Real-time price data arrives over sockets, purchases run through Apple and Google billing, releases are hardened with SSL pinning and secure storage, and App Store and Play submissions are mine end to end.

ARYA Crypto is the fourth surface: a web platform for managing crypto across exchanges, with a unified portfolio, target-weight allocation, dollar-cost-averaging rebalance rules, profit-protection exits and advanced order types. I built its entire front end in Next.js.
