Welcome to Duplicate Transaction (DT)
Hello, I’m Kourosh Tari, founder of Duplicate Transactions (DT)—a platform dedicated to sharing deep technical insight and practical guidance for building, integrating, and operating payment software in real-world environments.
With more than four decades of experience in software design and over a decade focused specifically on payment processing, I created DT to address a gap I repeatedly encountered: a lack of grounded, production-tested resources for professionals working inside complex payment ecosystems.
Here, you’ll find expert analysis, integration strategies, and developer-focused tools designed to simplify payment gateway connections and reduce operational risk. My work places particular emphasis on semi-integrations, transaction integrity, cybersecurity, and merchant-facing solutions—areas where small oversights often lead to costly failures.
As payment technology evolves, so do the challenges surrounding data security, compliance, and system reliability. My goal is not theory, but clarity—offering practical solutions you can apply with confidence in live environments.
Duplicate Transactions is also a collaborative space. I welcome shared experiences, emerging tools, and thoughtful discussion. Contributions from practitioners strengthen this platform and help elevate the quality of knowledge across the payments community.
Thank you for being part of the journey.
Warm regards,
Kourosh Tari
