Transaction systems
We build systems where payments, subscriptions, balances, market data, and product decisions need explicit state, reconciliation, and auditability.
Payments, ledgers, state, reconciliation
Commerce is financial software
Payments, subscriptions, credits, refunds, balances, and reconciliation demand the same explicit state and auditability as financial products.
Built in the category
Commodities · AI-Powered
Live commodities trading app - real-time gold, silver, oil, and agricultural prices, market dashboards, and portfolio tracking. Powered by Memox AI for commodity analysis and market commentary built directly into the app.
Crypto · Signal Delivery
End-to-end signal delivery system - trigger logic on price and volume, alert routing, user notifications, and multi-channel delivery at scale via push, Telegram, and SMS.
Mobile · Financial Data
Full-featured fintech mobile application - market data feeds, user portfolio management, financial analytics dashboards, and biometric authentication. Built for production, not prototype.
Applied intelligence
Most shops either skip AI entirely or bolt on ChatGPT and call it a feature. We’ve shipped our own agentic products - and we know exactly where AI helps and where you need proper quantitative engineering.
Market commentary & analysis, data ingestion agents, anomaly detection on price feeds, portfolio Q&A assistants.
Signal backtesting, risk models, order execution logic, P&L calculations & reporting. Deterministic math where hallucinations aren’t acceptable.
The transaction stack
Custom signal platforms - trigger conditions on price, volume, or custom indicators. Deliver alerts via push, SMS, email, or Telegram. Real-time feeds, not polling.
We architect the data layer underneath your app - routing, normalization, caching, delivery. FMP, Yahoo Finance, Alpaca, Binance wired together correctly the first time.
Real-time price dashboards for commodities, crypto, forex, equities. TradingView charts wired to your data feeds. Watchlists, portfolio tracking, P&L views.
Multi-asset portfolio management, performance analytics, allocation views, and AI-powered commentary on positions using our agentic stack.
iOS and Android apps for financial services - market access, account management, payment flows, biometric auth, and AI assistant integration.
How We Work
Integrity by design
We design the state model, failure paths, operator controls, and audit trail together. The interface is only trustworthy when the system behind it can explain what happened.

These are not separate agency departments. They are the technical disciplines required to own the path from customer action to operational outcome.
Questions
Yes - but here’s what most devs miss: TradingView is a charting UI layer, not a data provider. You bring the data (we architect that via FMP, Yahoo Finance, Alpaca), TradingView renders it. Most dev shops promise “TradingView integration” without understanding this, and it costs you 6 weeks. We’ve done this before. We come with the data architecture planned.
We move faster because we’ve already solved the hardest problems - the data architecture, API integration, real-time infrastructure. A focused signal app or dashboard MVP can be live in 6 - 12 weeks. Complex multi-asset trading platforms take longer. You’ll get a clear scope on your first call.
Depends on your asset class and budget. For equities and fundamentals, FMP is excellent and cost-effective. Yahoo Finance works for basic price data. Alpaca if you need brokerage plus data in one. For crypto, CoinGecko or Binance. Commodities is more nuanced - we’ve navigated this and will recommend the right stack, not the most expensive one.
Memox is our agentic AI product - we run it inside Bullionaire as a commodities analysis tool. Users can ask natural-language questions about their positions, get AI-generated market commentary from live price data, and receive proactive insights. If your fintech app needs an AI layer, we can integrate Memox or build a custom agentic system using the same architecture. We know exactly where AI helps and where you need deterministic math instead.
That’s where we do our best work. Most great projects started with “I want to build something like X for Y market.” We’ll pressure-test your idea, help you scope the MVP, choose the right data providers, and design the architecture - before any development contract is signed. First call is free and honest.
Transaction integrity
Bring the payment, subscription, ledger, or real-time data problem. We will make the state and failure modes explicit before we build.
