Background

About Arun Tyagi

I’m an experienced technology leader with deep expertise in developing and delivering payment applications on Android POS terminals, along with legacy Linux-based POS devices. I lead cross-functional teams of developers and QA engineers, managing the full software lifecycle — from sprint planning and development to certification, production rollout, and support. My background includes strong focus on PCI compliance, including PCI P2PE, PCI PIN, and PCI PTS standards. I also have extensive experience in cryptographic key management, specifically with MK/SK, DUKPT-2009, and DUKPT-2017 methodologies using TDES and AES encryption. I’ve successfully delivered certified payment solutions across India and APAC markets, including multiple certifications for Visa, Mastercard, RuPay, Amex, and Diners. This includes complex integration projects, production deployments, and partner enablement across regional fintech ecosystems. In addition to technical leadership, I bring strong project and people management capabilities, including resource planning, agile delivery under SAFe, and coordination with product, business, and security stakeholders. I actively contribute to product strategy, technical solutioning, and roadmap alignment to ensure timely and business-aligned outcomes. I value clarity, accountability, and continuous improvement. My focus is on building empowered teams, delivering secure and scalable products, and driving impactful results in both local and global markets.
