FAQ
Can you develop a custom AI fintech or payment application?
Yes. We develop tailored mobile and web fintech applications using frameworks like Flutter and React Native, paired with robust backends (Node.js, Python). Scope can range from lightweight MVPs to custom financial management systems based on your specific requirements.
Can you integrate payment gateways, digital wallets, and transaction APIs?
Absolutely. We integrate major payment gateways (Stripe, PayPal, Razorpay) and financial aggregation APIs (Plaid, Yodlee). Please note that active payment processing requires your business to hold valid merchant accounts and compliance credentials.
Can you develop blockchain applications and smart-contract functionality?
Yes, we implement Web3 wallet connectivity (MetaMask, WalletConnect) and integrate smart contracts on EVM-compatible blockchains. Smart contracts and decentralized features are built according to project specifications established during scoping.
Can you integrate AI features into an existing fintech application?
Yes. We can integrate AI capabilities—such as automated transaction categorization, predictive budgeting, and conversational finance bots—into existing applications via RESTful APIs and cloud backend services.
Can you build Android and iOS apps and assist with app store deployment?
Yes, we build cross-platform applications for both iOS and Android. We also provide full guidance for submitting your app to the Apple App Store and Google Play Store under your developer accounts.
