Background

About Nikolas Andreou

Goal-oriented IT professional with 15+ years of experience in payments, acquiring systems, and fintech integrations, combining strong technical expertise with proven leadership. I specialize in PSP integrations, payment flows (authorization, capture, settlement, refunds, chargebacks), and ISO 8583 systems, with hands-on experience in API/SDK integrations (Stripe, Apple Pay, Google Pay, Google APIs). My work includes driving PCI DSS compliance initiatives and implementing fraud prevention systems (FICO Falcon, FRMC/CCS, Strategy Director) to ensure secure, scalable solutions. As a Scrum Master and Technical Lead, I’ve managed cross-functional and distributed teams, overseeing the full lifecycle of integrations — from requirements and solution design to UAT, configuration, and operational readiness. I thrive in fast-paced, high-volume transaction environments where stakeholder alignment, vendor collaboration, and risk management are critical to success. Passionate about building payment solutions that are secure, seamless, and scalable, I bring both the strategic mindset of a product leader and the technical depth of a payments SME.
