Project details
Financial services is the #1 industry by AI adoption market share and a top-funded vertical SaaS category globally. Banks, fintech startups, lending companies, and investment platforms are racing to build cloud-native platforms that automate payments, detect fraud, and enable embedded finance.
I develop production-grade FinTech SaaS platforms payment gateways, lending management systems, invoicing & billing SaaS, trading dashboards, and financial analytics tools with bank-level security (PCI-DSS compliance), real-time data processing, and AI-powered fraud detection.
My platforms integrate with Stripe, Plaid, Open Banking APIs, and popular accounting tools.
