A fintech startup aimed to simplify digital banking for modern users but needed a secure, scalable platform that could support seamless account management, fast transactions, and strong data security.
Our Solution
We developed a secure fintech platform with modern app and mobile applications, integrating advanced authentication, real-time transaction tracking, and scalable cloud infrastructure.
fintech lending platform needed AI-powered credit risk analysis across hundreds of daily applications, but every borrower check, admin review, and compliance pull was triggering a separate API call. Costs were compounding fast and margins were at risk.
Our Solution
We built a "generate once, retrieve always" architecture. One structured OpenAI API call fires at application submission, the report is stored against the borrower's record, and every subsequent access pulls from the database.
