Arpan D.

Hi, I’m Arpan a AI Fintech expert. I help FinTech startups and financial platforms build secure, scalable, and integration-heavy products across banking, payments, lending, onboarding, and financial automation. I bring 15+ years of experience in FinTech product development and consulting, with hands-on work across Open Banking APIs, ACH flows, KYC/AML integrations, lending systems, and financial infrastructure. Clients usually work with me for three reasons: 1. Deep FinTech specialization I focus specifically on FinTech, which means I understand the product, compliance, integration, and operational complexity involved in building financial applications. 2. Strong integration experience I have worked with leading FinTech APIs and platforms such as Plaid, Dwolla, Finicity, Marqeta, Alloy, Onfido, Persona, Equifax, TaxJar, ADP, and others to build reliable and compliant user experiences. 3. Practical delivery mindset I help clients move faster by combining product thinking, technical execution, and real-world experience in security, privacy, and compliance-sensitive environments.
