CRYPTO

About this project

CRYPTO is a custom product designed, developed, tested and deployed by our team, with the source code and accounts handed over to the client.

A cryptocurrency mobile application: market data, portfolio tracking and price movement. Finance apps are read-heavy and latency-sensitive: users refresh constantly, and a stale number is worse than a slow one.

What a build like this covers

• Live market data with a caching layer, so the app is not hammering an upstream API on every screen focus
• Portfolio and watchlist with holdings, cost basis and profit/loss
• Price charts across multiple ranges, rendered from downsampled series rather than raw ticks
• Price alerts delivered by push
• Secure session handling with biometric unlock

What we watch for in finance work

We build market and portfolio tooling. We do not build custody, and we do not build anything that gives financial advice: those carry licensing obligations that belong with the client and their regulator, not with a development contract.

Stack

We build finance products in Flutter and native Android and iOS on the client, with Node.js and NestJS services behind them, TypeORM over PostgreSQL or MySQL where the data is relational, MongoDB where it is not, and Firebase for authentication, push and analytics. Web panels are React. The choice follows the product. We do not start from a template and bend the requirements to fit it.

How we work

Every project starts with a written scope and screen list, moves through design and iterative development with regular demos, and ends with testing on real low-end devices before release. Clients own their code, repositories and store accounts. Where it adds genuine value, we integrate AI features (assistants, document extraction, recommendations) rather than bolting them on for show.
