FinTech web applications need to handle money, which means every architectural decision has financial consequences. TechSaaS builds fintech platforms with transaction integrity, real-time updates, and security as foundational requirements, not afterthoughts.

BizStreet/InstaFunding is a Turborepo monorepo we built for WhatsApp-first startup funding. The web dashboard provides investors with deal flow management, pitch deck viewing, due diligence tracking, and portfolio analytics — all synced with the WhatsApp conversational interface.

We integrated HyperSwitch, an open-source payment orchestration system, into our platform stack. This gives our fintech clients intelligent payment routing across multiple processors, automatic failover, and unified reporting across payment methods.

Our fintech applications use real-time WebSocket connections for live price updates, transaction notifications, and collaborative deal rooms. We build with optimistic UI patterns so interfaces feel instant even when backend confirmations take time.
