I’m Manish, a payments professional passionate about simplifying the world of card processing, EMV technology, ISO standards, and financial systems. I’ve worked hands-on across card issuing, tokenization, PCI-DSS compliance, mobile wallet systems, and payment gateway integrations—helping teams understand and implement real-world transaction flows from both issuer and processor perspectives.

Over the years, I realized that card payments are one of the most misunderstood areas in FinTech. Many professionals use these systems daily but never get to see what happens behind the scenes: EMV commands, APDU structures, ISO 8583 messaging, authorization logic, clearing/settlement, and risk controls. My goal is to make these complex topics simple, visual, and practical for anyone entering or growing in this industry.

I teach using real examples, processor-level insights, and step-by-step breakdowns drawn directly from my experience in banking and FinTech environments. Whether you’re a developer, QA engineer, product manager, or a payments enthusiast, my courses are designed to help you build strong technical foundations and accelerate your career in the payments domain.
